Product Description

Optical Glass Flat Mirror is ideal for a variety of applications including interferometry, imaging systems, laser applications, optical path folding, and auto collimation. These Optical Mirrors are available in a variety of coating and substrate options. 

China star optics designs and manufactures a great choice of various high reflecting mirrors for the spectral range:UV,visible,near infrared,and infrared regions. Besides optical glass Flat mirror, Optical Glass Concave Mirror,and Optical Glass Plano Concave Mirror, hot mirror,laser mirror,dielectric mirror,hyperbolical mirrors can be customized upon request. 

Silicon features a Knoop Hardness of 1150 and low density, making it tougher than germanium substrates and suitable for weight-sensitive applications, respectively.Our common Silicon Lens and Silicon Mirror can be coated on the surface (Antireflection Coating), which can reduce the reflectivity to less than 1.5% between 3 to 5 um.
Some silicon lens and silicon mirror are exposed to dust, acid, salt and so on in the harsh environment. The conventional multilayer antireflection coating will be damaged and affect the normal work of the equipment. At this time, we need to make Diamond-Like Carbon DLC coating on the surface of the silicon lens.
Diamond-Like Carbon (DLC) Coated Silicon optics lens and Silicon mirror are engineered for 3 to 5µm, making them ideal for infrared defense applications such as thermal imaging.
