OPT-13 GLASS LENSES: CONVEXO-CONCAVE

These lenses have one concave and one convex side. The concave face has a greater degree of curvature than the convex face.

They are thicker at the periphery than at the center, and are also referred to as the negative meniscus lenses.

These lenses are commonly used as corrective lenses.

Our lenses are made of optically worked glass, with ground edges and a highly polished surface.

They are available in two sizes:

1. Convexo-concave glass lens with diameter=50mm and focal length=500mm
2. Convexo-concave glass lens with diameter=50mm and focal length=1000mm
3. Convexo-concave glass lens with diameter=75mm and focal length=500mm
4. Convexo-concave glass lens with diameter=50mm and focal length=1000mm

Lenses made of extra-white glass are also available.
