Meniscus lenses are convex-concave lenses. They have one outward curved face and one inward-curved face. If the outward curve is sharper than the inward curve, the lens has a positive focal length and acts as a magnifier.

Experimental Quality Positive Meniscus 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.
