Facimton Optical Technology Inc.

Optical windows are used to allow optical radiation to pass from one environment to another without allowing other elements of these environments to mix. And it does not change the wavelength distribution of the beam,the transmitted wavefront, nor does it scatter any of the light out of the beam.

Our company offers windows with a variety of materials, including BK7, fused silica, float glass, Si, Ge, and so on. They are good quality, durable and strong. To select a window, material, transmission, scattering, wavefront distortion, parallelism, and resistance to environment should be considered.We produce kinds of window with different substrate for your selection:
