Professional High Reflective Film 1064 Bandpass Interference Filter

Professional High Transmission Laser Receiving Instruments 1064 Bandpass Filter

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

fim. 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.

Founded in 2001, Beijing jinji'aomeng Technology Co., Ltd. is the first professional coating company in China, which was reformed from Beijing Jingnan Applied Technology Research Institute, which was founded in 1993. The company is the earliest private optical coating manufacturer.
