Abstract
A spectrometer assembly is provided having an optical transmission filter including a stack of continuous, non-patterned alternating dielectric and metal 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.
