FOCOVISION SR-2

«

»

The Focovision by Reflection SR-2 is used in the production of semifinished lenses, glass and metal molds,but also in prescription laboratories to control the incoming semi-finished
lenses. It measures the surface optical power by reflection on one point with a high degree of accuracy. The measured value can be expressed in curvature or in diopter. The
Focovision by Reflection has become a worldwide reference instrument throughout the ophthalmic industry.

Benefits

High accuracy (0.01D for the base power, less than 0.01D for the residual astigmatism of the instrument)
Very high reproducibility
Precise and reproducible positioning of the lens according to reference points marked over the lens surface
Simple and rapid autocalibration procedure
No moving parts (behaviour stability, simple lighting system, ...)
Linear instrument response (no mechanical adjustments are necessary)
Reliability : Image quality control & automatic correction of dust effect
Measurement time : in practice, instantaneous for the operator (including tolerance checks)
Long life and easily replaceable lamp

Technical information

Range :

Optical Power in the main axes : -12D to +12D (assuming 1.5 index - the range expressed in diopters is larger for higher index values)
Addition : any value if measurements are inside the above limits
