As more and more "easier to filter" sodium vapour street lights are replaced with white LED street lights, light pollution has gotten all the more tricky to deal with. The IDAS LPS-D2 filter is the IDAS answer to this new threat. It targets heavily the strong blue component present in these lights, as well as eliminating the warmer part of their emission curve from about 555nm to 640nm.
IDAS LPS-D2 filters are currently available as camera body-mounted filters for Canon DSLR cameras, SONY A7 series cameras or as screw-in filters for telescopes or telephoto lenses.
