LINK AL-1200

The instrument works out what it is measuring

The LINK AL-1200 is a touch screen focimeter that identifies lenses for itself. Upgraded Hartmann intelligent measurement handles high refractive index and polarised materials automatically, a green LED source removes Abbe coefficient compensation, and an on-screen electronic rangefinder covers distance and height measurement.

Practices Dispensing Modern Lens Materials

High refractive index lenses have become ordinary rather than exceptional, and polarised lenses arrive routinely with prescription sunwear. Both can trouble measurement, and an instrument that identifies and handles them automatically keeps them inside the normal verification routine. The practical benefit is consistency: the same procedure applies whether the lens in the holder is a standard plastic single vision or a polarised high index progressive, and the operator does not need to know which before starting.

Progressive Lens Verification and Centration

Progressive designs are determined quickly and automatically, and the on-screen electronic rangefinder covers the distance and height measurements that govern where the corridor sits relative to the eye. Having both on one instrument matters because a progressive complaint can originate either in the lens or in how it was centred. Being able to examine both without changing instruments makes that distinction quicker to reach and easier to explain to the patient.

Verification by Staff Without Specialist Training

Because the instrument identifies the lens itself and requires no Abbe setting, the number of decisions asked of the operator is small. Practices that delegate verification to support staff benefit most, since fewer decisions mean fewer opportunities for an inconsistent result. Touch operation on a high definition display keeps the interaction direct, which shortens the time before a new member of staff can be trusted with the task unsupervised.

Everyday Spectacle and Contact Lens Checking

Sphere to plus or minus 25D, cylinder and addition to plus or minus 10D and axis across the full range cover ordinary dispensing comfortably, with soft and hard contact lenses included in the measuring modes. Cylinder in plus, mixed or minus mode and prism in Cartesian or polar form mean output matches whatever convention the practice already records against, without anyone converting figures by hand.

Fewer Decisions, Fewer Inconsistencies

Automatic lens identification and the absence of any Abbe setting together strip most of the judgement out of taking a reading. That matters less for the specialist who would get those decisions right anyway, and a great deal for a practice where verification passes between several people with different levels of experience. An instrument that asks little of its operator produces records that stay comparable regardless of who was at the bench. Consistency across operators is what makes a verification record worth keeping.

Difficult Materials Handled as Routine

High refractive index and polarised lenses are precisely the items that generate awkward exceptions on a bench that cannot manage them. Exceptions consume disproportionate time and tend to end in a judgement call rather than a measurement. Bringing these materials into the normal routine returns that time and replaces the judgement with a figure that can be written down and defended later.

Power and Centration on One Screen

The electronic rangefinder puts distance and height measurement on the same display as the power reading. When a patient reports that a new pair is uncomfortable, the two candidate explanations are the lens itself and how it was positioned. Having both sets of figures from one instrument, in one sitting, is what turns that conversation from speculation into something specific. One sitting also spares the patient a second appointment.

Automatic Lens Identification

The instrument identifies and measures various lens types without being told which is which. Removing that declaration removes a step where an incorrect selection can produce a confidently wrong reading.

High Index and Polarised Materials

High refractive index and polarised lenses are identified and measured automatically. These are the materials that most often produce unstable readings, and handling them as routine avoids setting work aside.

Green LED Source Without Abbe Compensation

A green LED illuminant means Abbe coefficient compensation is not needed. A material dependent correction that has to be configured correctly is simply absent from the workflow.

Upgraded Hartmann Intelligent Measurement

The measurement technology is an upgraded Hartmann arrangement, which the manufacturer describes as faster, more accurate and more stable than the version it supersedes.

Rapid Progressive Determination

Progressive lenses are determined quickly, automatically and with high precision. Progressive designs are the hardest to classify by inspection, so automatic determination is most valuable exactly here.

Electronic Rangefinder on the Display

Distance and height measurement appears as an electronic rangefinder on screen. Centration figures are read from the same display as the power result, without a separate device or a separate step.

Seven-Inch High Definition Touch Display

A 7.0-inch high definition touch colour LCD presents readings and takes input directly. Control sits on the screen itself rather than across a bank of physical keys.

Food Grade ABS Shell

The instrument shell is manufactured from food grade ABS material, a specification the manufacturer states for the housing of this model.

The LINK AL-1200 touch screen focimeter is built to work out what it is measuring. Upgraded Hartmann intelligent measurement identifies and handles high refractive index and polarised lenses automatically, determines progressive designs quickly and precisely, and needs no Abbe coefficient compensation because of its green LED source. Sphere is measured to plus or minus 25D, cylinder and addition to plus or minus 10D in increments down to 0.01D, and axis across the full range in single-degree steps, with soft and hard contact lenses both included and cylinder and prism shown in your preferred notation.

A 7.0-inch high definition touch colour display carries both the readings and an electronic rangefinder for distance and height, so power and centration figures come from one instrument. The housing is food grade ABS material. The manufacturer specification for this model is less complete than for some others: instrument dimensions, weight, lens diameter, measuring speed, mains requirements and the prism measuring range are not clearly stated, and we would rather tell you that than guess. Ask Medigear.uk to confirm those figures along with certification status, condition, available variants and reseller and listing rights for the manufacturer trademark. Speak to Medigear.uk, a verified medical equipment supplier, and we will get you the full specification before you commit.

Frequently Asked Questions

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

The instrument determines what kind of lens has been placed in the holder and measures it accordingly, including high refractive index and polarised materials and progressive designs. The operator is not asked to select a lens type beforehand, which removes a step where an incorrect choice produces a reading that looks perfectly plausible but is wrong.

Sphere covers zero to plus or minus 25D, and cylinder and addition each cover zero to plus or minus 10D, all selectable in 0.01D, 0.06D, 0.12D and 0.25D steps. Axis runs from 0 to 180 degrees in single-degree steps. Cylinder can be displayed in plus, mixed or minus mode, and prism in Cartesian or polar representation. Those spans cover the great majority of prescriptions met in ordinary dispensing work.

Because it makes Abbe coefficient compensation unnecessary. That compensation varies with lens material and has to be set correctly for readings to be dependable, so a wrong value introduces error that is easy to miss. Removing the requirement removes the risk from everyday operation.

It provides distance and height measurement, shown on the display alongside the lens readings. These are the centration figures that determine how a lens sits in front of the eye, and having them on the same screen as the power result means both can be assessed together in one sitting.

Soft and hard contact lenses are both within the measuring modes, so power can be confirmed on the same instrument used for finished spectacles. That keeps the checking routine uniform across the different work a dispensary handles. Both power and the general condition of the lens surface can be considered while it sits in the holder, which is useful when a wearer reports that a lens no longer feels as it did.

Through a 7.0-inch high definition touch colour LCD display. Input is taken on the screen itself, so the operating sequence is followed by touch rather than across a set of physical keys, and readings are presented on the same high definition panel. Fewer physical controls also means fewer parts exposed to daily wear at a busy bench.

The manufacturer specifies food grade ABS material for the instrument housing. That is the material stated for this model, and questions about durability expectations or finish are best directed to Medigear.uk.

The manufacturer specification for this model does not state the prism measuring range clearly, although prism is measured and can be displayed in Cartesian or polar form. Rather than publish a figure we cannot verify, we would ask you to confirm the prism range with Medigear.uk before relying on it.
