IR lens is precise optic component
that can cope with IR wavelength,
and made of special materials usable
for UV and even IR.
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.
