White Ls108 Spectrum Transmission Meter For The Transmittance Or Barrier Rate

LS108 spectrum transmission meter is a professional optical transmittance tester for measuring the spectacle lenses, coating materials, organic materials, anti-blue light materials and other materials. The meter combines three measuring light paths into one. Users can select to measure the transmission rate or rejection rate. Four display interfaces can be switched. The LS108 spectrum transmission meter uses a 395nm purple light source, a 430nm blue light source and a visible light source to illuminate the transparent material during test. The sensor detects incident light intensity of the three light sources and the light intensity after passing through the transparent material. The ratio of transmitted light intensity to incident light intensity is transmittance, displayed as a percentage.
Rejection rate=100%- transmission rate

1.The meter is widely applicable
The spectrum transmission meter has a wide range of applications, suitable for the transmission and rejection rate test of glasses, glass, anti-blue light materials, mobile phone lenses, etc

2.Measure multiple sets of data at once
The light transmission meter can simultaneously measure the transmission value and rejection rate of 430nm blue light /395nm purple light /380nm-760nm visible light and UV400 (the maximum ultraviolet rejection wavelength)

3.Three-in-one light source path
The meter uses one light path. Three transmission values can be obtained by measuring one time

4.Testing of UV400 is available
The UV400 is an important parameter used to judge the UV protection ability of sunglasses. If the average transmittance of the ultraviolet rays below 400 nm is not more than 2%, and the wavelength transmittance of more than 400 nm is less than 5%, the lens meets the requirements of UV400. The instrument can measure the UV400 and detect the UV protection of the lens

5.Real-time dynamic self-calibration
The meter has a real-time dynamic self-calibration function, the transmission meter will be automatically calibrated to 100% transmission or 0% rejection after powering off or when starting a new measurement

6.Small test aperature
The test aperture of the instrument is 1mm, and the distance between the light source and the detector is 20mm which can measure large thickness materials

7.LCD screen, fashionable and easy for reading
Large LCD screen display, exquisite and stylish appearance, can be used in exhibitions and so on

8.Providing various display interfaces to choose
The spectrum transmission meter has two display interfaces in Chinese and English. Four interfaces can be selected:blue light/purple rejection+UV400

Using large LCD screen for easy reading
Real-time dynamic self-calibration function, which automatically calibrates to 100% transmittance after turning on
5V mobile power, easy to connect
