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.
