DESCRIPTION

LEMA ULT is a photometer that provides the following information on the measured lens (in percentage):
1) Transmittance at 400nm (UV400)
2) Transmittance in the visible range. This is detected on 3 points of the spectrum and an average transmittance value is obtained through an algorithm (tolerance 2%)
3) Transmittance at 950 nm (Infrared light) 

Basing on the three points detected for the visible, the values RGB (red, green, blue) are provided as well. These values determine the chromatic coordinates X and Y in CIE 1931 color space.
This information is displayed on PC, thanks to the software that is supplied with the device.
