No Paint High Reflective Film No Bevel Hot Mirror Filter Borofloat Substrate

A hot mirror used on medical instruments to prevent infrared hot radial penetrate

Reflective fims can generally be divided into two major categories, one is a metal reflective fim, and the other is an all-dielectric reflective

film. In addition, there is a metal dielectric reflective film that combines the two. These three high-refiection fims are available.

Generally, metals have a large extinction coefficient. When a light beam is incident on a metal surface by air, the amplitude of light enteringthe metal is rapidly attenuated, so that the light energy entering the metal interior is correspondingly reduced, and the refiected light energyis increased. The larger the extinction coefficient, the faster the attenuation of the light amplitude, and the less the lignt energy entering themetal interior, the higher the reflectivity. People always choose those metals with large optical coefficients and stable optical properties asmetal fim materials. The thin metal material commonly used in the ultraviolet region is aluminum. Aluminum and silver are commonly usedin the visible region, and gold, silver and copper are commonly used in the infrared region. In addition, chromium and platinum are alsocommonly used as fim matenials for special fims. Since materials such as aluminum, silver, and copper are easily oxidized in the air tolower the performance, they must be protected by a dielectric film. Commonly used protective fim materials are silicon oxide, magnesiumfluoride, silicon dioxide, aluminum oxide, and the like.
