Description

The OptoSigma 013-1880 lens has a diameter of 25mm and a focal length of 100.60mm. Made of Grade A BK-7 glass and uncoated, this lens is 3.5mm thick in the center and 2.0mm thick on the edge. Clear aperture is greater than 90%, surface quality is 20-10, and centration is equal to or less than 1 arcmin. Symmetrical biconvex lenses are most useful when dealing with finite conjugal points. This makes them ideal for imaging uses and multiple-element systems. New and still wrapped in factory tissue.
