9 exhibits a change in the transmission efficiency of the dichroic filter over the wavelength range from 515 nm to 545 nm.
It is a well suited material for use in optical components such as dichroic filters or hot and cold mirrors that rely on high thermal resistance as well as on high energy radiation exposure capabilities.
In addition, the dichroic filter arrays are passive and integrated, so requirements for a multispectral camera are the same as the base monochrome camera.
1] mirror and two dichroic filters (DF1 and DF2); this provided a coherent "white" light beam to the output with R, G and B components.
The key to viewing the combined hologram in white light is the placement of two dichroic filters between the three holograms to form a 'stack'; the filters ensure that the light is filtered in such a way that the appropriate wavelength illuminates each hologram.
Optical thin films available include BBAR, V-coats, dielectric high reflectors, beam splitters, aluminum, silver and gold metallic mirrors, and neutral density and dichroic filters.
JDS Uniphase contributed high-performance dichroic filters that have a rejection ratio of more than a billion-to-one.
If you have enough lead time to plan, you might create a layout and order dichroic filters and that might help.
Dichroic filters will let certain wavelengths pass and reflect other wavelengths 45[degrees].
