LINK ARK-1800

General optometry practices use the ARK-1800 as a routine screening instrument for sphere, cylinder, and axis measurements before full refraction, where auto-focus and the icon-based menu reduce the time and training required compared with older manual instruments. Equipment reliability is a recurring concern for busy practices with tight booking gaps, and a well-documented, function-tested unit reduces the risk of unplanned downtime that could disrupt a fully booked clinic schedule running back-to-back appointments.

Ophthalmology and cataract screening clinics rely on the ARK-1800's keratometry function to assess corneal curvature and astigmatism ahead of contact lens fitting or surgical planning discussions, where accurate corneal power data supports informed clinical decisions made jointly with the patient. The device's combination of refraction and keratometry in a single instrument reduces the required equipment footprint compared with separate standalone devices for each measurement.

Multi-practitioner clinics and teaching environments favour the ARK-1800's 85-degree tilting touchscreen, which supports comfortable use across different practitioner heights and working styles without requiring the unit to be physically moved between sitting and standing operators. This flexibility matters most in shared consulting rooms where staff rotate through the same station across a busy shift.

Distributors and multi-site optical group buyers use the ARK-1800 as a standardised diagnostic instrument for outfitting multiple locations consistently, since its wide 100V-240V power range operates reliably across different regional power standards without requiring modification or a separate transformer. Medigear.uk supports these buyers with bulk configuration advice, staggered delivery scheduling, and consistent documentation across multi-unit orders.

Combined Refraction and Keratometry in One Instrument

The ARK-1800 measures sphere, cylinder, axis, and corneal parameters from a single device, reducing the equipment footprint and cost compared with separate standalone refractometer and keratometer instruments. This consolidation is one of the unit's most practical everyday advantages for space-constrained practices.

Hexagon Prism and CCD Precision

A high-quality hexagon prism paired with a highly sensitive CCD sensor is what the manufacturer credits for the unit's accuracy and reliability, supporting confident clinical readings across repeated use.

Auto Focus Reduces Operator Variability

The device auto-focuses as soon as it is moved into position, reducing the dependence on operator skill for consistent results and supporting more repeatable measurements across different staff members using the same unit.

85-Degree Tilting Touch Screen

The touchscreen's 85-degree tilt range provides the operator a comfortable viewing angle whether sitting or standing, supporting comfortable use across different practitioner heights without repositioning the whole unit.

Wide Voltage Range Simplifies Multi-Region Deployment

Running on 100V to 240V at 50 or 60Hz means the same unit specification works across a very wide range of regional power standards without a separate transformer, a genuine advantage for distributors supplying multiple markets from a single configuration.

CE-Marked, Procurement-Ready Documentation

Units come with available service history and documentation appropriate for procurement review at the point of purchase. That documentation is usually the deciding factor in how quickly a capital equipment purchase clears sign-off. Medigear.uk can confirm the additional paperwork required by a specific trust or clinic 

Fast Thermal Printer With Auto Cutter

The built-in fast thermal printer, with easy loading and an auto-cutter function, provides immediate results at the point of examination without a separate connected printer.

Distributor and Multi-Site Configuration Support

Distributors and optical groups sourcing for multiple locations get consistent unit specification and staggered delivery scheduling through Medigear.uk, simplifying procurement across several sites at once. Bulk pricing and lead-time coordination are handled directly with the Medigear.uk sales team.

Single-Supplier After-Sales Support

Buyers deal directly with Medigear.uk for warranty terms, service queries, and any follow-up support rather than coordinating between separate equipment vendors. That single point of contact simplifies ongoing equipment management for busy practices.

Sphere Range: -20D to +20D

Spherical measurement across this range, in steps as fine as 0.12D, covers the great majority of adult refractive error encountered in routine screening.

Cylinder Range: -8D to +8D

Cylinder measurement across this range, in steps as fine as 0.12D, supports precise astigmatism power determination.

Axis Measurement: 0° to 180°, 1° Steps

Full-axis-range measurement in single-degree increments supports precise astigmatism axis determination.

Pupil Distance Range: 45–88mm

Pupil distance measurement in 1mm steps covers the great majority of adult patients encountered in routine screening.

Corneal Power Range: 33.75D to 67.50D

Keratometry measurement across this range, based on a corneal equivalent refractive index of 1.337, supports routine corneal curvature assessment.

Corneal Astigmatism Range: 0.0D to 8.0D

Astigmatism measurements in increments as fine as 0.12D support contact lens fitting and pre-surgical screening.

Corneal Diameter Range: 2.0–14.0mm

Corneal diameter measurement in 0.1mm increments supports contact lens fitting and general corneal assessment.

Minimum Measurable Pupil Size: 2.0mm

A minimum measurable pupil size of 2.0mm supports reliable measurement even in patients with smaller pupils.

7-Inch TFT LCD Touch Screen

The touch screen display provides a clear, icon-based interface for reviewing and confirming measurement results.

85-Degree Screen Tilt

The screen tilts through 85 degrees, supporting a comfortable viewing angle for operators whether sitting or standing.

Follow-Up Colourful Fogging Chart System

The fogging chart system supports standard refraction technique, helping relax patient accommodation during measurement.

Built-In Fast Thermal Printer With Auto Cutter

Easy-loading thermal printing with an auto-cutter function provides immediate results at the point of examination.

Data Storage: 10 Readings Per Eye

The device stores 10 measured values for each of the left and right eyes, supporting comparison across repeated measurements.

Wide Power Supply: 100V–240V, 50/60Hz

The unit accepts a wide input voltage range, making it adaptable across most regional power standards without a separate transformer.

The LINK ARK-1800 auto refractometer keratometer gives opticians, hospitals, and distributor networks a combined refraction and keratometry instrument for routine sphere, cylinder, axis, and corneal curvature measurement, whether that's a busy general optometry practice, an ophthalmology screening clinic, or a multi-site optical group standardising diagnostic equipment across locations. Its hexagonal prism precision, autofocus operation, and 85-degree tilting touchscreen keep both measurement consistency and day-to-day comfort practical for busy clinics. At the same time, its wide-voltage compatibility simplifies deployment for distributors supplying multiple regions. Documentation and service history should be confirmed on the specific unit being purchased before procurement sign-off.
