Giai photonics Co.,Ltd
Narrowband filter main role is to make the specific wavelengths of light by reflection, let the other wavelengths of light (or decay) optical elements. Half wave width usually controlled to 20nm or less, ultraviolet, visible, near infrared wavelength, infrared band. Narrow band filter our company adopts multi-layer dural by ion assisted deposition of nano materials and high vacuum evaporation coating, good compactness, high image resolution.
Wavelength: 515 ± 7Nm
Through rate: T=60%
Stop band 400nm-480nm
Cutoff rate: T<0.1%
Hard coatings, long service life,
