SCIPLUS IS OUR NAME, OPTICS IS OUR GAME

Al Luebbers, our founder, collected glass. Not glass like you'd find on a knick-knack shelf, but optical glass. Lenses, prisms, reticles and filters, for example. Focus on the filters. Many of his filters came out of military surplus, and this is for-real stuff. We mean many are solid dyed optical glass, ground and polished to flatness standards that were probably excessive. Others are from the old days in photographic optics, and their standards were even tighter than your militaristic Uncle's. This one is amber in color and 30mm diameter. 2.3mm thick and is not mounted. Great for experimenting and for artists. Have fun, we know he did.
