Abstract:
A glass substrate has excellent optical transmittance for the visible spectrum (400–700 nm). This study used
three type glass (D263TTM, EAGLE XG○,R, and BK7) for laser micro-structuring in the light compensation
technique applied to a multi-wavelength mixed light module. An ultraviolet laser system combined with a
high-speed galvanometric scanner was used to fabricate microstructures on the specimen surface. The light
compensation chromaticity properties of the microstructures on glass substrates depended on the laser
machining conditions. The characteristics of the machined glass were systematically analyzed using a
spectrophotometer and charge-coupled device camera. The experimental results demonstrate that the
microstructures affected chromaticity under different laser micro-structuring pitches.
