Long-Wavelength Pass Filte
- The long wave pass filter allows light with a wavelength greater than the set wavelength to pass through, and light with a wavelength less than the set wavelength is cut off.
- The long wave pass filter provided by Borisun optics has the advantages of wide cut-off band, deep cut-off depth, high conversion steepness and high transmittance. It can also be widely used in spectral measurement, optical imaging system, optical imaging system and so on.
|Optical grade float glass(B270) or UV fused quartz(JGS1)
|Central wavelength（ λ C) Tolerance
|Transmitted wavefront error
|Gradient of cutting band
In addition, We can customize the optical filters according to customer requirements or drawings.
