-This double-convex glass lens is made of polished optical glass. It measures 38mm in diameter and has a focal length of 5cm.
Sold in a pack of 20 lenses.The glass lens provides superior optical clarity, lower distortion, and minimal chromatic aberration (color fringing).The lenses are well-made to avoid spherical aberration, where light rays from different parts of the lens don't converge at the same point, resulting in blurry images.
