LINK ARK-980

General optometry practices use the ARK-980 as a routine screening instrument for sphere, cylinder, and axis measurements before full refraction, where autofocus and one-touch operation 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.

Ophthalmology and cataract screening clinics rely on the ARK-980'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.

Optical retail settings, including independent opticians and busier high-street practices, favour the ARK-980's built-in thermal printer and touchscreen interface, which give staff and patients immediate, shareable results without a separate connected printer or a manual data-entry step slowing things down. The freely rotating screen also supports flexible instrument placement across different room layouts and workflow arrangements.

Distributors and multi-site optical group buyers use the ARK-980 as a standardised diagnostic instrument for outfitting multiple locations consistently, since its wide AC 100-250V, 50/60Hz voltage range operates reliably across different regional power standards without requiring modification. 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-980 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.

Auto Focus Reduces Operator Variability

Hartman imaging analysis, combined with autofocus and auto-measurement, reduces dependence on operator skill for consistent results, supporting more repeatable measurements across different staff members using the same unit.

Wide Voltage Range Simplifies Multi-Region Deployment

Running on AC 100-250V at 50/60Hz 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.

Built-In Thermal Printer for Immediate Results

Immediate, on-the-spot printed output removes the need for a separate connected printer, giving practitioners and patients shareable results at the point of examination.

Freely Rotating Touch Screen for Flexible Placement

The screen's ability to rotate up, down, left, and right supports comfortable operator positioning and flexible instrument placement across different room layouts and workflows.

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.

Electric Forehead Rest Adjustment

The electric lifting forehead rest automatically adjusts to maintain consistent patient positioning, reducing manual repositioning effort for staff throughout a busy day of appointments.

Distributor and Multi-Site Configuration Support

Distributors and optical groups sourcing for multiple locations can achieve consistent unit specifications and staggered delivery schedules 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: -20.00D to +20.00D

Spherical measurement across this range, in steps as fine as 0.01D, covers the great majority of adult refractive error encountered in routine screening.

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

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

Vertex Distance Settings: 0.0, 12.0, 13.75, 15.0mm

Multiple vertex distance settings allow measurement to be adjusted for different lens and frame configurations.

Pupil Distance Range: 10–86mm

Wide pupil distance measurement range covers the great majority of patients, from children through to adults.

Corneal Power Range: 33.00D to 67.00D

Keratometry measurement across this range, based on a corneal equivalent refractive power of 1.3375, supports routine corneal curvature assessment.

Corneal Astigmatism Range: 0.00D to 15.00D

Astigmatism measurements in increments as fine as 0.06D support contact lens fitting and pre-surgical screening.

Minimum Measurable Pupil Diameter: 2.0mm

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

Measuring Light Energy: Under 30 Microwatts

Light energy is kept below 30 microwatts to ensure measurement safety across repeated examinations.

10.4-Inch SHARP TFT LCD Touch Screen

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

Freely Rotating Screen Positioning

The screen rotates up, down, left, and right, supporting flexible instrument placement and comfortable viewing angles for the operator.

Built-In 57mm Thermal Printer

Automatic paper-cutting thermal printing provides immediate result output at the point of examination without a separate printer.

Electric Lifting Forehead Rest

The forehead rest adjusts automatically, supporting consistent patient positioning between examinations without manual effort from staff.

Data Storage: 10 Readings Per Eye

The device stores the last 10 measured values for both the left and right eyes, enabling comparison across repeated measurements.

Wide Voltage Range: AC 100-250V, 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-980 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 Hartman imaging-based autofocus, wide-voltage compatibility, and built-in thermal printer keep both measurement consistency and day-to-day workflow practical for busy clinics. At the same time, its freely rotating touch screen supports flexible placement across different consulting room layouts. Documentation and service history should be confirmed on the specific unit being purchased before procurement sign-off.
