Chroma Filters

Chroma Filters, the ones professionals use at many major observatories, NASA and JPL.
In business for 24 years and experienced in several scientific disciplines, Chroma has made filters for many “famous name” companies in the past, but now operates under its own banner.

Custom filters, in terms of size, extreme F ratios and bandpass, are a speciality – just ask!
