IR LONG PASS FILRER COATING
Procuct of IR Long Pass Filter
The use of infrared optical systems often requires the protection of the exposed front surface for the impact to the extreme environment. To this end, we provide a carbon (DLC) coating such as diamond, each of the optical elements. In addition to the anti-reflection effect, the coating is also characterized by external stress, a very high mechanical strength and high elasticity.
Optical components are coated with the silicon and germanium of 3-5㎛ to 8-12㎛ wavelength range.
In addition to the standard coating, we also provide a customized design.

IR ANTI-REFLECTION COATING
AR (Anti-Reflective) coating technology is specifically designed for the far-infrared range (8-12 µm). This coating is applied to germanium materials used in infrared optics, particularly in thermal imaging systems, to enhance transmission and reduce reflections, thereby improving overall optical performance.
