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.
