The ability to quickly insert and remove filters makes these mounts ideal for holding filters in the middle of an optical train. A plunger on the bottom of the holder ''pops'' the filter up for easy removal. A light tight cover prevents leakage of ambient light into the enclosed optical path. We offer these holders for all three series of condensing lens assemblies.
