Not only the usual refractometry and keratometry, but also corneal diameter and base curve of contact lens can be measured with this one instrument. Thus, measurements of eye and prescriptions for glasses and contact lenses can be made more efficiently.
Refraction & Keratometry Measurement
VRK-2400 provides an extensive range of dioptric measurement range. It covers -25D to +22D, and the radius of curvature for keratometry is 5.0mm to 10.2mm. Owing to its easy alignment and friendly operation you can measure the refraction and keratometry in a sequency, the results can be checked all at once.
Using the VRK-2400's Freeze Function, you can measure the diameter of the cornea, pupil or hard contact lenses worn by process is both easier and more precise.
Colored picture notice table
A wide visual field angled color picture notice table makes easy to fix patients' eye through making patients confortable. An auto cloud and mist function is helpful t ochildren or damaged eyes because it affects to machinery near vision and patients control.
Auto PD Measurement / Automatic power saving
It can measure and indicate pupils' distance can be measured automatically by using measurement of reflection eyes.
If VRK-2400 not used over 5 minutes, it shut off from electric power saving function eliminates current to the TV monitor and lighting circuitry. It conserves energy and prevents any build-up of heat from electronic circuitry, increasing its useful life.
VRK-2400's friendly convinient fuctions
CLBS (Contact Lens Base Curve)
CLBS supports easy to measure posterior curve of hard contact lens.
VRK-2400 provides intuitive user interface and it contains a fixed gripe of stage and a power sign light.
Easy handling joystick
It can be measured by only one hand. Even novices can use it with precise results.
Direct results indication
Through monitor, you can see the results(maximum of 10 data for each eye) of measurements stored in memory.
Built-in printer provides fast and perfect clear paper that is placed VRK-2400's front-right side.
Transmission of data
measured data an be delivered to the external instrument (PC, phoropter) through RS-232.
