LS108 (Model): Product Features: 1mm test aperture, capable of measuring transmittance and blocking rate of 395nm purple light, 430nm blue light, full-band visible light, and UV400, suitable for anti-blue light material testing.
LS108 Blue-Purple Light Tester is professionally used to detect transmittance, blue light blocking rate/transmittance, and ultraviolet blocking rate/transmittance. It is applicable to various organic materials, coated materials, anti-blue light materials, such as spectacle lenses, mobile phone films, tempered glass, etc. Aligning the aperture once can test three data and calculate UV400, with powerful functions and easy operation.
Core Advantages:

Can detect UV400 (maximum blocking ultraviolet wavelength) to determine whether spectacle lenses meet the UV400 standard.
Three-in-one optical path design, aligning the aperture once can measure transmittance, blue light blocking rate/transmittance, ultraviolet blocking rate/transmittance, and UV400.
With power-on self-calibration and real-time dynamic calibration functions, no manual calibration is needed, and measurement is fast and accurate.
Can switch between Chinese and English language display, and has four measurement interfaces that can be switched.
