LS108 Spectrum Transmission Meter

LS108 Spectrum Transmission Meter


I. LS108 Spectrum Transmission Meter Introduction

Linshang LS108 spectrum transmission meter is a blue-violet tester for testing eyeglass lenses. It can test the transmittance of blue light 430nm, visible light 380nm-760nm full wavelength, in line with CIE photopic luminosity function and purple light 395nm. It is suitable for eyeglass lenses, blue light-proof materials, coating materials, organic materials, PC materials, etc. Anti-blue light test, light transmittance test and UV test for substances.

The testing principle of the LS108 blue-violet light tester is to use a purple light source, a blue light source and a visible light source to illuminate the tested transparent material. The sensor detects the incident light intensity of the three light sources and the light intensity after passing through the tested transparent material. The ratio to the incident light intensity is the transmittance, expressed as a percentage. The instrument has simple operation . The data can be displayed on the interface immediately with high accuracy.
