The Visionstar ACP-1800 is a programmable auto chart projector for the refraction lane. It projects 30 chart patterns at 30× magnification, giving a 330 × 270 mm image at 5 metres, and works at any projection distance from 1.5 to 6 metres — which covers both a direct long lane and the shorter mirrored rooms common in UK high-street premises.

Programmability is the feature that changes how a practice works rather than merely what it owns. Two programmes are stored, each holding up to 30 steps, so the entire sequence of a sight test can be defined once and then run identically by whoever is in the room. For practices using locums, running multiple clinicians across a week, or supervising pre-registration trainees, that turns the test order from an individual habit into a practice standard. It also removes the small hesitations of hunting for the next chart on a handset mid-examination.

Chart and mask both switch in 0.03 seconds. The mask plate provides 36 positions in total: one open, five horizontal line masks, eight vertical line masks, 21 single-letter masks and one red/green. Single-letter isolation matters clinically — it removes contour interaction, which is what separates a genuine acuity limit from a crowding effect, and it is essential in amblyopia assessment and paediatric work where crowding phenomena are diagnostically significant.

A 410 × 410 mm metal plate with polarised coating is supplied as standard, along with polarised glasses. This is what makes polarised binocular testing possible — dissociating the two eyes optically so binocular balance, stereopsis and fixation disparity can be assessed — and it pairs directly with the polarising filters carried on the auxiliary dial of most phoropters.

The light source is a 12V 50W halogen lamp on the A, B and C variants, or an LED module on the LA, LB and LC variants. Auto-off engages after 10 minutes idle. Lamp replacement is designed to be straightforward and requires no refocusing. Chart content differs between the A, B and C variants; the appropriate chart set for UK use must be specified at order. Medigear.uk supplies the ACP-1800 with pre-despatch functional inspection and documentation review.

Standardising the sight test across clinicians is the application with the clearest operational value. UK practices routinely run locums alongside permanent staff, and every optometrist arrives with their own habitual test order. Two stored programmes of up to 30 steps let a practice define its sequence once and have it reproduced identically regardless of who is testing, which matters for record consistency, for supervising pre-registration trainees, and for any practice where audit or protocol adherence is a concern.

Amblyopia and paediatric assessment depend on the mask capability. Contour interaction means a letter presented within a line is harder to resolve than the same letter alone, and the difference between crowded and isolated acuity is a recognised diagnostic feature in amblyopia. Twenty-one single-letter masks alongside line masks make that comparison routine rather than improvised, which supports both detection and the monitoring of occlusion or atropine therapy over time.

Binocular vision assessment uses the polarised screen and glasses supplied as standard. Optical dissociation of the two eyes underpins binocular balance, stereopsis and fixation disparity testing, and having the polarised plate included rather than as a chargeable extra means the capability is present from day one. It complements the polarising filters on a phoropter's auxiliary dial directly.

Room geometry drives the practical fit. A projection distance range of 1.5 to 6 metres accommodates the mirrored six-metre lanes standard in UK practice as well as shorter direct rooms where mirroring is impractical. Practices should settle two things before ordering: the chart variant must be confirmed as appropriate for UK acuity notation, since the manufacturer's variants carry different letter sets and character systems, and the halogen or LED light source decision should be made on expected lane volume rather than headline price.

The test order becomes a practice standard

Two programmes of 30 steps mean the sight test sequence is defined once and reproduced by everyone. Locums, trainees and permanent staff all run the same examination, which improves record consistency and makes protocol adherence something the equipment supports rather than something the practice hopes for.

No hunting for the next chart

Programmed sequences advance with a single press. The small hesitations of searching a handset mid-examination disappear, which sounds trivial until you count how many times it happens across a full appointment list.

Instant switching in both directions

Chart and mask each change in 0.03 seconds. Nothing is lost to the mechanical delay of the instrument, so the patient's attention and fixation stay where they should be.

Isolated letters distinguish crowding from acuity

Twenty-one single-letter masks let a clinician remove contour interaction and see whether a patient's limit is genuine acuity or a crowding effect. In amblyopia assessment and paediatric work that distinction is diagnostically significant, not cosmetic.

Polarised testing included as standard

The 410 mm polarised metal plate and polarised glasses ship with the unit, so binocular balance, stereopsis and fixation disparity assessment are available immediately rather than as a chargeable addition.

Fits short rooms and mirrored lanes alike

A 1.5 to 6 metre projection range covers the mirrored six-metre lane standard in UK practice and the shorter direct rooms where mirroring is impractical, so room geometry rarely rules the instrument out.

Straightforward lamp replacement

Bulb changes need no refocusing or repositioning, so a lamp failure costs minutes rather than a service visit. Halogen variants ship with a spare.

LED option removes a recurring cost

The LED variants eliminate lamp replacement and reduce heat output in a small room. For a busy lane the whole-life cost comparison generally favours LED despite the halogen versions' lower entry price.

Auto-off protects the lamp and the room

Powering down after 10 minutes of idle time extends lamp life on halogen units, reduces heat build-up in a confined consulting room, and means a projector left on at the end of a clinic does not run all night.

Two programmable sequences

Two stored programmes each hold up to 30 steps, allowing the full sight test order to be defined and reproduced identically by any clinician using the room.

Thirty chart patterns

The unit projects 30 different chart patterns, covering distance acuity, astigmatic and red-green targets, and the specialist charts used across a routine examination.

Thirty-six mask positions

The multi-function mask plate provides one open position, five horizontal line masks, eight vertical line masks, 21 single-letter masks and one red/green mask.

0.03-second chart switching

Chart conversion completes in three hundredths of a second, fast enough that the change is effectively instantaneous to the patient.

0.03-second mask switching

Mask conversion matches the chart speed, so isolating a letter or a line interrupts nothing in the examination sequence.

Projection distance 1.5–6 m

The projector operates at any distance from 1.5 to 6 metres, accommodating both mirrored six-metre lanes and shorter direct rooms.

30× magnification at 5 m

Magnification is 30× at 5 metres, producing a 330 × 270 mm projected image at that distance.

410 × 410 mm polarised screen

A metal plate with polarising coating is supplied as a standard part, enabling polarised binocular testing with the included glasses.

Polarised glasses supplied

Polarised viewing glasses ship with the unit, completing the optical dissociation needed for binocular balance and stereopsis assessment.

Halogen or LED light source

A 12V 50W halogen lamp on the A, B and C variants, or an LED module on the LA, LB and LC variants, with the choice made on expected lane volume and whole-life cost.

Auto-off after 10 minutes

The unit powers down automatically after 10 minutes of idle time, extending lamp life and reducing heat output in a confined room.

Tool-free lamp replacement without refocusing

Lamp changes require no adjustment to focus or position afterwards, so a failure is resolved in minutes without a service call.

Horizontal axis tilt correction

A tilted mounting position is corrected by adjusting the projector's horizontal axis rather than repositioning the entire unit.

Remote control operation

A handheld remote drives chart selection, mask selection and programme sequences from the clinician's working position.

Complete accessory set

Remote control, polarised metal screen, polarised glasses, two fuses and two batteries are supplied with every variant, plus a spare halogen lamp on halogen versions.

The Visionstar ACP-1800 is a programmable auto chart projector that turns a practice's sight test sequence into something reproducible. Two stored programmes of up to 30 steps, 30 chart patterns, 36 mask positions including 21 single-letter isolations, and 0.03-second switching on both chart and mask give a clinician everything needed for distance acuity, astigmatic, red-green and crowding assessment without touching anything but the remote. A 410 mm polarised screen and glasses ship as standard for binocular balance and stereopsis work, projection distance runs from 1.5 to 6 metres to suit both mirrored and direct lanes, and the light source is specified as halogen or LED according to lane volume. It suits practices standardising across locums and trainees, those doing serious paediatric and amblyopia work, and any lane where consistency matters. Two decisions belong at order rather than after: the chart variant must be confirmed as appropriate for UK acuity notation, since the A, B and C variants carry different letter sets, and the halogen or LED choice should be made on whole-life cost. Medigear.uk supplies the ACP-1800 into the UK with pre-despatch functional inspection, documentation review and chart variant confirmation.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

That needs settling explicitly at order. The A, B and C designations carry different chart content — the manufacturer's own illustrations show different letter sets and character systems across them, and at least one is not Latin script. A UK practice needs Snellen or logMAR letters appropriate to British acuity notation. Confirm the exact chart content in writing before ordering rather than assuming a default.

The A, B and C variants use a 12V 50W halogen lamp; the LA, LB and LC variants use an LED module. LED gives longer service life and lower heat output, and removes the recurring cost and downtime of lamp replacement. Halogen lamps are cheap and easy to source, and the halogen variants ship with a spare. For a practice running a busy lane, the LED variant generally makes more sense over the instrument's life.

A standard sequence that every clinician follows. Two programmes of up to 30 steps each mean the sight test order is defined once — distance acuity, red/green, astigmatic fan, binocular balance, near, whatever the practice agrees — and then reproduced identically by locums, trainees and permanent staff. Beyond consistency, it removes the pause where a clinician searches the handset for the next chart.

Because contour interaction changes what a patient can read. Letters presented in a line are harder to resolve than the same letter presented alone, and the difference is diagnostically meaningful — the crowding phenomenon is a recognised feature of amblyopia, and isolating letters distinguishes a true acuity limit from a crowding effect. Twenty-one single-letter masks give that capability across the chart.

It enables polarised binocular testing. The 410 × 410 mm metal plate carries a polarising coating, and with the supplied polarised glasses each eye sees only part of the projected image. That optical dissociation is what allows binocular balance, stereopsis and fixation disparity to be assessed, and it complements the polarising filters found on the auxiliary lens dial of most phoropters.

Yes. Projection distance runs from 1.5 metres to 6 metres, so both a direct short lane and a full-length room are within range. Most UK practices work at an effective 6 metres achieved with a mirror, which this accommodates, but the short-distance capability suits rooms where mirroring is not practical. Note that image size scales with distance — the quoted 330 × 270 mm applies at 5 metres.

Minimally. The manufacturer states that focus and position adjustment are unnecessary, and that a tilted placement can be corrected by adjusting the projector's horizontal axis rather than by repositioning the whole unit. That said, the geometric relationship between projector, screen and patient still needs setting out properly, and the screen must be square to the patient's line of sight.

It sits on a table, a shelf or an instrument arm. Several phoropter arms are rated to carry a chart projector alongside the refractor head, which consolidates both instruments onto one fixing and sets their alignment together. If you are specifying a mounting arm at the same time, confirm the projector loading rating and bracket compatibility before ordering either.

The unit powers down after 10 minutes of idle time. On halogen variants this meaningfully extends lamp life and reduces heat in a small room; on LED variants the benefit is mostly energy and heat. It also means a projector left on at the end of a clinic does not run overnight.

A chart projector is a non-invasive ophthalmic device, most consistently classified as Class I under the UK Medical Devices Regulations 2002, or higher where configuration dictates. Manufacturer CE marking is noted where it appears in the product literature; Medigear.uk confirms CE marking, the declaration of conformity and current UKCA status against the shipping batch at quotation rather than asserting it in advance.

Remote control, polarised metal screen, polarised glasses, two fuses and two batteries on all variants, with a spare halogen lamp additionally supplied on the halogen versions. Confirm the exact accessory schedule for the variant quoted, since the LED versions omit the lamp for obvious reasons.

Lamp replacement on halogen variants, which the manufacturer states is straightforward and needs no refocusing — keep a spare beyond the one supplied. Keep the projection lens and the polarised screen clean, since dust on either degrades contrast at exactly the acuity limits being measured. Replace remote batteries as needed. Typical warranty is 12 to 24 months against manufacturing defect, confirmed at quotation.
