LS183 Spectrum Transmission Meter

LS183 Spectrum Transmission Meter


I. LS183 Spectrum Transmission Meter Introduction

Linshang LS183 spectrum transmission meter is mainly used for the optical performance test of thermal insulation coatings, single-layer glass, laminated glass (insulating glass), stick-film glass, PMMA, PC and other materials. It can simultaneously test the transmittance of ultraviolet, infrared and visible light. The width of the test slot is 47mm. The IR transmission meter use the parallel light path source. When testing large thickness materials, the data is also very accurate. The light transmission meter manufacturers offer preferential prices.

The LS183 spectrum transmission meter use ultraviolet light source, infrared light source and visible light source to illuminate the tested transparent material. The sensor detects the light intensity of the three light sources and the light intensity after transmitting the tested transparent material. The ratio of the intensity to the incident light intensity is the transmittance, expressed as a percentage.
