LS108 blue-violet light Tester is a professional optical transmittance Tester for spectacle lenses, coating materials, organic materials, anti-blue light materials and other substances. It can test the transmittance of blue light 430nm, white light 380nm-760nm and purple light 395nm. This instrument combines these three measured light paths into one, and can measure three data at one time. Display items include visible light/blue light/purple light transmittance+UV400, visible light/blue light transmittance+UV400, visible light/blue light/purple light transmittance three interfaces for users to choose.
The testing principle of LS108 is to use purple light source, blue light source and visible light source to irradiate the tested transparent material, and the sensor respectively detects the incident light intensity of the three light sources and the light intensity after passing through the tested transparent material, the transmitted light intensity and the incident light intensity The ratio of is the transmittance, expressed as a percentage. The instrument is exquisite, compact and beautiful, and it can be measured immediately after release, and the data is accurate.


1. The scope of use of the instrument is very wide, and it is suitable for the transmittance test of glasses, glass, anti-blue light materials, mobile phone lenses, etc.
2. The instrument can simultaneously measure the transmittance of blue light with a peak wavelength of 430nm, the transmittance of violet light with a peak wavelength of 395nm, the transmittance of visible light with a peak wavelength of 380nm-760nm, and the maximum ultraviolet blocking wavelength.
3. The instrument uses a three-in-one optical path design, that is, the transmittance of blue light, purple light, and visible light can be measured in the same optical hole. Easy operation saves measurement time.
4. The instrument has real-time dynamic self-calibration function, and the instrument will automatically calibrate to 100% transmittance after starting up or starting a new measurement.
5. The test aperture of the instrument is Φ1mm, which can measure materials with large thickness.
6. Compared with the old instrument, the new instrument is small in size and easy to carry. Large LCD display, exquisite and fashionable appearance, can be used to participate in exhibitions and so on.
7. The instrument has two display interfaces in Chinese and English. The display items include visible light/blue light/purple light transmittance+UV400, visible light/blue light transmittance+UV400, and visible light/blue light/purple light transmittance. Users can choose by themselves .
