Dual Spectrometer

«

»

The dual stand alone Spectrometer has been designed for the light wavelength spectrum measurement by reflection from, and transmission through a lens positioned between the measurement heads.

The device is not ambient light sensitive. In so doing, that system is well suited for the identification of the anti-reflective coating as well as the identification or the control of the lens colour. The software includes some advanced comparisons algorithms for checking or finding the match between the measured colour and a set of reference colours.

Similar algorithms are used for the identification check of the anti-reflective coating. In the same way, there is the possibility to make a pairing check test (matching of colour between left and right lens), to calculate colour spaces coordinates and distances acording to ISO and CIE standards and to measure the thickness of the varnish (assuming its index is not equal to the substrate index).
