GLASS LENSES, DOUBLE CONCAVE, DIAMETER:50MM

• Double concave or biconcave lenses have two concave surfaces, which are symmetrical with equal radius of curvature on both sides.
• Our lenses are made of high quality optical glass, with finely ground edges.
• These lenses are not mounted.
• They are great for optical benches and form an important part of many experiments in optics, along with other lenses.
• Thus, students can apprehend how these lenses diverge the incident light, and henceforth find application as beam expanders and in projection systems.
• Dimensions: Diameter of the biconcave lenses is 50 mm.

Biconcave lenses with different focal lengths are available with us:

1. Biconcave lens with focal length= 50 mm.
2. Biconcave lens with focal length= 100 mm.
3. Biconcave lens with focal length= 150 mm.
4. Biconcave lens with focal length= 200 mm.
5. Biconcave lens with focal length= 250 mm.

• Our biconcave lenses with a diameter of 50mm are also available with focal lengths in the range of 300 mm to 1000 mm.
• The biconcave lenses made of extra-white glass are also available with us.
