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.
This is an affordable, good-quality lenses which performs well for many types of classroom experiments.
Great for various lab experiments such as physics demonstrations
Sold in a pack of 20 lenses.
