LS108H Spectrum Transmission Meter

LS108H Spectrum Transmission Meter


I. LS108H Spectrum Transmission Meter Introduction

Linshang LS108H spectrum transmission meter is a desktop optical transmittance meter, mainly used to measure the transmittance of various uniform and transparent materials. The test aperture of the instrument is 3mm, which is suitable for the transmittance, infrared and ultraviolet transmittance measurement of small size materials. The flat bench-type design is convenient for placing various test samples. The accurate data will be immediately displayed on the interface. With parallel light path design, the LS108H visible light transmission meter can measure thicker materials. 

The LS108H spectrum transmission meter use ultraviolet light source, infrared light source and visible light source to illuminate the tested transparent material. The sensor detects the intensity of the incident light of the three light sources and the light intensity after transmitting the tested transparent material. The ratio of the transmitted light intensity to the incident light intensity is the transmittance, expressed as a percentage.
