Test UV400 / VLT / blue and violet light transmittance Special for anti-blue and UV proof materials 1mm test aperture
LS108 spectrum transmission meter is a professional optical transmittance tester for measuring the spectacle lenses, coating
materials, organic materials, anti-blue light materials and other materials. The meter combines three measuring light paths into
one. Users can select to measure the transmission rate or rejection rate. Four display interfaces can be switched. The 999D
spectrum transmission meter uses a 395nm purple light source, a 430nm blue light source and a visible light source to illuminate
the transparent material during test. The sensor detects incident light intensity of the three light sources and the light
intensity after passing through the transparent material. The ratio of transmitted light intensity to incident light intensity is
transmittance, displayed as a percentage.
The meter is widely applicable
The spectrum transmission meter has a wide range of applications, suitable for the transmission and rejection rate test of glasses, glass, anti-blue light materials, mobile phone lenses, etc
