OPT-12 GLASS LENSES: CONCAVO-CONVEX

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

They are thicker at the center than at the periphery, and are also referred to as the positive 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. Concavo-convex glass lens with diameter=50mm and focal length=500mm
2. Concavo-convex glass lens with diameter=50mm and focal length=1000mm
3. Concavo-convex glass lens with diameter=75mm and focal length=500mm
4. Concavo-convex glass lens with diameter=50mm and focal length=1000mm

Lenses made of extra-white glass are also available.
