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.
9 exhibits a change in the transmission efficiency of the dichroic filter over the wavelength range from 515 nm to 545 nm.
Dichroic Filter Arrays are high-precision optical filters that selectively transmit light according to its wavelength.
Extremely durable optical coatings include anti-reflection, infrared thin film coatings, dark mirrors, patterned optical filters, advanced multispectral optical filter assemblies, dielectric, multilayer, and dichroic filters.
The dichroic filters provide better colour re-creation than coloured LEDs that will colour degrade over time, and their resistance to temperature and humidity assures colour consistency for the life of the fixture.
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].
