1.1 Optical reflective film

Features：The function of reflective film is to increase the reflectance of optical surface. It can be divided into three categories, namely, metal reflective film, all dielectric reflective film and metal-dielectric reflective film. Among them, all dielectric reflective films can have characteristics of high reflection and low absorption in different spectral band.

Application: It can be used in the manufacture of light reflection, refraction and cavity devices, and has a wide range of application fields in laser, LED, optical instrument, and laser display, etc.

Products：We can provide narrow bandwidth (spectral range 6-20 nm), medium bandwidth (100-200 nm) and large bandwidth (300-500 nm) optical high reflective (HR) coatings.
