| Display | 4.0" 480X320 LCD screen |
| Minimum test lens size | Diameter: 1mm |
This multi-function UV & Blue light Tester BU-300 testing principle uses four different wavelength light sources in the table below to irradiate the transparent substance under test. The sensor detects the intensity of the same light source passing through the transparent substance under test and the incident intensity. The ratio of the two is used as the transmittance, which is displayed as a percentage.
Mainly used for testing the optical performance of transparent materials for eyeglass lenses, anti-blue light coating materials and organic materials, etc.
