Optical filter can be divided into ultraviolet filter, visible filter, and near-infrared filter by wavelength .

Optical filter by depositing one or more layers of metal or dielectric materials on optical components such as glass, crystal, semiconductor,

plastic, change the transmission characteristics of light waves, including Light transmission, reflection, absorption, scattering, polarization,

and phase . The optical filters of HZXD OPTICS are widely used in biochemical instruments, microplate readers, various laser range finder,

fluorescence microscope, various spectrophotometers, spectrum analysis instruments, photographic lenses, DVD laser probes, stage

lighting equipment, lasers. Machine, CCD imaging, criminal investigation, monitoring, security equipment, etc.

HZXD OPTICS' filter is deposited by IAD or IPD, The structure of the film is dense and the wavelength is stable.
