Astronomical Filters
Asahi has provided astronomical filters, dichroic beam splitters, or windows with broadband AR to world's well-known observatories
in Chile, Hawaii, Canary, and Arizona for over twenty years.
Unlike cheap astronomical filters for amateurs sold online, Asahi astronomical filters are fabricated to meet many hard requirements
for sciences from professional astronomers.
We are always willing to challenge new technologies to cooperate with the unique instruments.
Let's discuss with us what you currently require for your science.
