WebReflectivity of Light Light is reflected differently from various surfaces and colors. An understanding of these differences is useful in choosing colors and materials for clothing, in choosing colors for cars, and in city planning. Astronomers use reflectivity differences to help determine characteristics of planets. WebThe reflectivity or absorption of a material is an important parameter in LBC. The reflectivity of any metal is affected by several factors as follows: As the wavelength of the laser becomes shorter the reflectivity decreases and the absorptivity of the surface increases.

WebSome materials can be used for either IR or visible applications, most notably fused silica, BK7 and sapphire; however, the performance of an optical system can be optimized by using materials better suited to the task at hand.
