Photometer “Kolir” is designed to measure the spectral coefficients of diffuse reflection in laboratory conditions and calculate the whiteness, transparency, opacity and color characteristics of reflective materials according to different standards and measurement systems on their basis.
This device is equipped with a color wheelbarrow. the display, on which the main control buttons are located, allows you to receive detailed information on the measurements taken.
Measurement conditions – illumination/observation d/0, measurement aperture (diameter) – 30 mm.
Illumination source – white LED, ultraviolet LED.
The photodetector is a spectrometer with a diffraction grating and a 256 element CMOS receiver. The spectral measurement interval is 400 – 740 nm with a resolution of 10 nm. Results in tabular and graphical forms.
