Plano-convex (PCX) lenses have one flat and one outward curved face. They have a positive focal length, making them ideal for collecting and focusing light in imaging applications.
25mm and Larger Experimental Quality Plano-Convex (PCX) 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.
