J457 CLR Contact Lens Refractometer

The J457CLR contact lens refractometers are designed for measurement of contact lenses both hard and soft as well as accurately checking saline solutions and are an ideal replacement for the Index Instruments CLR 12-70 contact lens refractometer.
The instrument is available in two versions:

The FC model comes with a Rudolph supplied display, nothing needs to be added, the user simply removes it from the box and connects to power. If the user wants transfer results to a PC they can but they do not have to

The CB model comes with a USB connection cable and software. Thus, ready to be connected to a user supplied PC. All results automatically save on that PC

Easy Loading
Soft contact lenses are easy to tear and hard to position correctly. The J457 positions the loading low and directly in front of the operator making it easy to position the lens with the hands in a supported position.

Soft Positioning
The J457 has a soft positioning device that gently lowers the contact lens into the measuring position and minimizes changes due to compression.

Variable Pressure
An adjustable weight system allows a user to choose the amount of pressure to put on the contact lens and then put that same amount of pressure on every time.

Small Measuring Spot (MIO)
A conventional J457 measures along a strip a few mm long. An application like a contact lens in saline where there are different refractive indices requires a much smaller measuring spot, The MIO optics uses a different focusing system to create that smaller spot.
