Raman Long Pass Edge Filter 25mm Diameter Block 441.6nm

RSF-25C-442RU

It is available to cut the excitation laser beam and extracted with high transmittance Raman shifted light on the longer wavelength side with a sharp rise. It can be used to detect weak light of the Raman scattering.
◦At the wavelength of the laser specified it has excellent light-blocking properties of OD6 and in the transmission range it is a filter with a transmittance of more than 90%.
◦Because it is a dielectric multilayer coating, there is almost no absorption of light by the coating.

Guide
  • Please contact our Sales Division for customized products. (customized of outer diameter, wavelength characteristic, etc.)
  • Please contact our Sales Division if you require a wavelength characteristics of broadband data or more detailed data.
  • Please refer to here for "Wavelength Characteristic Data (Reference Data, Transmittance: T[%]) " for each wavelength.
Remark -
Attention
  • If the light incident angle is other than 0 degrees, the transmittance characteristics may change. In normal use, when the incident angle changes, the wavelength may shift to the long wavelength side.
