Measuring device for measuring the refraction properties of optical lenses

An spectacle lens (07) refraction property measurement unit (01) has a measurement light array (06) generating several light beams refracted by the lens through a screen (10) with several apertures to a detector (11) connected to a processor. Independent claims are included for the addition of a sys...

Summary:An spectacle lens (07) refraction property measurement unit (01) has a measurement light array (06) generating several light beams refracted by the lens through a screen (10) with several apertures to a detector (11) connected to a processor. Independent claims are included for the addition of a system using reflected light to measure the front surface of the lens.
