Principle:

The narrow-band filter allows the optical signal to pass through a specific band, and the optical signals on both sides that deviate from this band are blocked. The passband of the narrow-band filter is relatively narrow, generally less than 5% of the central wavelength value.

 

Function:

The main function of the narrow-band filter is to pass light of a specific wavelength and to reflect (or attenuate) light of other wavelengths. The half-wave width is usually controlled at 20nm or less, and can be used in ultraviolet, visible, near-infrared, and far-infrared wavelengths. Our company’s narrow-band filter is made of multilayer hard film by ion-assisted deposition of nanomaterials and high vacuum evaporation. The film layer Good compactness, high imaging clarity.

 

Advantages:

1.Single-piece type does not use gluing

2. Hard coating, long service life

3. Accurate wavelength positioning

4. Ion evaporation, small temperature drift

5.High penetration rate

6.High cut-off depth
