RSF-25C-458RU Filter for Spectroscopy

[Features]
· Cutting the pump laser light, with a sharp rise, the Raman shift light on the long wavelength side can be extracted at a high transmittance.
· Can be used for detecting faint Raman scattered light.
· In the laser wavelength, this filter features light blocking properties superior to those of OD6 and has transmittance that exceeds 90% in the transmission band (RSF-25C-325RU is 80% or more).
· There is almost no light absorption by the film thanks to the dielectric multilayer film coating.
· * The transmittance wavelength characteristics may change if using an incident angle other than 0°.
· * In general, the larger the incident angle, the more the wavelength characteristics shift to the shorter wavelength side.
