Though more fundamental and rather classical photometric system, U, B, V, Rc, Ic filters are still important for astronomers.
We can provide not only typical U, B, V, Rc, Ic filters made by colored glasses, but also the filters with interference film combination.
Notice : Due to the discontinuation of GG385 and BG12 (Schott), we currently make B filter by using L-38 (HOYA) and BG25.
