LS163 (Model): Product Features: 6mm slot, 940nm infrared/ultraviolet rejection rate, transmittance, 3 interfaces, rotatable screen, suitable for testing solar film and side window glass
LS163A (Model): Product Features: 6mm slot, 1400nm infrared/ultraviolet rejection rate, transmittance, 3 interfaces, rotatable screen, suitable for testing solar film and side window glass
LS163/LS163A is a compact, portable and feature-rich solar film tester with built-in light sources for three different wavelength bands: visible light, infrared, and ultraviolet. Three display modes are optional to meet different testing needs. It is mainly used to detect the light transmittance performance of solar film, filmed glass and automobile side window glass.
Visible Light Transmittance VLT:
Also known as transmittance. The higher the transmittance, the better the light transmission performance of the solar film.
Ultraviolet Transmittance UVT/Rejection Rate UVR:
The higher the ultraviolet rejection rate (the lower the transmittance), the better the ultraviolet blocking performance of the solar film.
Infrared Transmittance IRT/Rejection Rate IRR:
The higher the infrared rejection rate (the lower the transmittance), the better the heat insulation performance of the solar film.
Core Advantages:

Built-in three light sources: visible light, ultraviolet, and infrared, multi-functional in one machine
Three display interfaces (rejection rate, transmittance, and light transmittance) can be switched
Adopts parallel optical path design, which can accurately measure solar film and side window glass
Rotatable screen design, can rotate in 4 directions, easy to read measurements at any angle
