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.
