LS108H spectrum transmission meter is a desktop instrument, which is exclusively designed for optical transmittance test of various materials such as lens, glass, coating material, organic material and paint, etc. The test aperture of the meter is 1mm, which is suitable for the measurement of light transmittance, infrared and ultraviolet transmittance of small size materials. The flat bench-top meter is available for placing various test samples. The test is fast and accurate. Once the test material is placed on the meter, the test results will be displayed immediately. The meter use parallel light path design that can measure thick materials.
The LS108H optical transmittance tester use ultraviolet light source, infrared light source and visible light source to illuminate the transparent material. The sensor detects the incident light intensity of the three light sources and light intensity after passing through the transparent material under test. The ratio of the over light intensity to the incident light intensity is the transmittance shown in percentage.
It is suitable for measuring the transmittance of various uniform transparent materials, such as glass, PC, coated glass, IR hole on the remote control window, plastic, paint, lens, organic glass (acrylic), etc.

1. The difference between LS108H and LS183 spectrum transmission meter
Both LS183 and LS108H spectrum transmission meters can measure the transmittance of infrared, ultraviolet and visible light.
1) LS183 use a card slot design with a detector hole diameter of 10mm and width between the light source and the receiver is 47mm.
2) LS108H use a desktop design, the detector hole diameter is only 1mm and the height between the light source and the receiver is 20mm.
LS108H is suitable for measuring small-sized materials and more widely used, so the price of LS183 is slightly higher. LS183 is suitable for measuring large-sized materials.
