Highly Reflective Thin-Film Optimization for Full-Angle Micro-LEDs

WebVarious basic properties characterize a mirror: Figure 1: Reflection of light on a mirror. The reflectivity (or reflectance) is the percentage of the optical power which is reflected. Generally, it depends on the wavelength and the angle of incidence, for non-normal incidence often also on the polarization direction.; The reflection phase is the phase shift of … WebHighly reflective (HR) coatings are used to minimize loss while reflecting lasers and other light sources. Absorption and scatter during reflection lead to decreased throughput and potential laser-induced damage. HR coatings are used in common laser optics applications such as folding a laser’s beam path and laser cavity end mirrors.
