Overview
The DR82B blue-violet light transmittance tester is a small Benchtop Optical inspection transmittance tester, which specializes in the detection of various myopia Glasses lenses, reading glasses lenses, display lenses and anti-blue light materials. Optical inspection transmittance detection. The instrument adopts a three-in-one optical path design, and can measure visible light, blue light, purple light transmittance and UV400 four sets of data at one time. It can also measure visible light transmittance, blue light blocking rate, purple light blocking rate + UV400 four sets of data.
This instrument mainly uses visible light Illuminant, 430nm blue light Illuminant and 395nm purple light Illuminant to illuminate the transparent substance to be measured. The sensor detects the incident ray intensity of the three Illuminants and the light intensity after passing through the transparent substance to be measured. The ratio of light intensity to incident ray intensity is the transmittance, expressed as a percentage, 1-transmittance = barrier rate. The instrument is exquisite, small and beautiful, ready to be measured immediately, with accurate data, suitable for field testing or laboratory use.
Features
1. Test visible light, blue light, purple light transmittance or blocking rate + UV400
2. Three-in-one optical path design, one hole can be measured four sets of data, easy to operate, time-saving measurement
3. Parallel light design, the measurement results of large thickness materials are stable and accurate
4. The test aperture is 1.3mm, which can test the transmittance of small-sized materials
5. With real-time automatic measurement, Dynamic Automatic calibration function, Automatic calibration to 100% transmittance after startup
6. The instrument comes with a Type-C interface, which can be connected to a computer PC to realize the function of transmitting data
7. Test methods: CONTINUE and SINGLE Measurement mode
8. The operation process is marked with a beep sound (Single Measurement mode)
9. Mass storage, capable of storing 10 sets of data, 200 in each group, for a total of 2,000
10.5-Inch LCD color display
11. Chinese and English bilingual versions
12. It is powered by 5V power supply, which is convenient to connect to a mobile power supply (power bank) for use
Principle
This instrument mainly uses visible light Illuminant, 430nm blue light Illuminant and 395nm purple light Illuminant to illuminate the transparent substance to be measured. The sensor detects the incident ray intensity of the three Illuminants and the light intensity after passing through the transparent substance to be measured. Light intensity and incident ray intensity The ratio is the transmittance, expressed as a percentage, 1-transmittance = barrier rate.
