WebEmissivity is a measure of a material’s ability to emit infrared energy. Emissivity is typically measured on a scale from 0.00 to 1.00. Reflectivity on the other hand, is how much light is reflected from the materials surface. Emissivity is defined by a ratio of infrared energy emitted by an object, compared to that emitted by an ideal ... WebThis is Section 11.4 of the Laser Optics Resource Guide. Highly 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 ...
