Spectroscopic assembly and method
A spectrometer assembly is provided having an optical transmission filter including a stack of continuous, non-patterned alternating dielectric (28) and metal (27) layers. Angle-dependent transmission wavelength shift of the optical transmission filter with continuous metal layers is small e.g. in c...

Zusammenfassung: | A spectrometer assembly is provided having an optical transmission filter including a stack of continuous, non-patterned alternating dielectric (28) and metal (27) layers. Angle-dependent transmission wavelength shift of the optical transmission filter with continuous metal layers is small e.g. in comparison with multilayer dielectric filters, facilitating size reduction of the spectrometer assembly. |
