Product Description

Product Description

Visible Light Transmitter Reflectivity Haze Tester VLT VIST
1. Equipment introduction
This instrument uses tungsten halogen lamps, parallel light tubes, integral spheres, photocells, etc. to test the ratio of luminous flux before and after passing through the glass. Through a special filter, the spectrum of the tungsten halogen lamp is filtered out from ultraviolet and infrared components, and the spectrum is corrected to the relative radiation spectrum of the D65 light source, and the total transmittance of visible light in glass that meets the requirements of national standard GB2680-1994. If no spectral correction is made, it is an A light source, meeting the technical requirements of the GB5137.2-2002 "Automatic Safety Glass Optical Performance Test Method" standard. By adjusting the position of the light barrier plate inside the integral sphere and the position of the sample, the transmittance, reflectance and haze of the glass can be tested separately. If you only need to test the transmittance of the sample, you can choose our company's BTG-3S visible light transmittance tester. Except for the different test purposes, other parameters are consistent with BTR-1S.
