Double Concave Lens, Glass, 38mm x 10cm (#L201)
This Double Concave Lens feature a 38mm diameter with a 10cm focal length. A concave lens has an inward curve in the middle. In other words, the edges of the lens are thicker than the middle. This causes light that enters the lens to spread out, or diverge. This makes images appear smaller when viewed through a concave lens. Everyday uses for concave lenses include flashlights, peep holes in doors and eyeglasses for myopia, or nearsightedenss.
