Double-concave (DCV) lenses have two inward curved surfaces and a negative focal length. They are used for image reduction and to spread light.

Experimental Quality Double-Concave (DCV) Lenses are offered in several experimental grade options. Grade 1 is standard optical glass, edged, free of visible scratches, chips, stains, or oxidation. Grade 2 is unedged, non-optical glass, small chips, slight stains, or other defects. They may have slight edge cement separation.

Note: Specifications for experimental grade optics may vary as much as 10% from those listed. Also, no additional information is available other than what is provided.
