High transmittance range wavelength
High transmittance range transmittance
Blocking laser wavelength
Zoom

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.

▶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.

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.
