OPT-11 GLASS LENSES, DOUBLE CONCAVE, DIAMETER:75mm

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 75 mm.

Biconcave lenses with different focal lengths are available with us:

1. Biconcave lens with focal length= 100 mm.
2. Biconcave lens with focal length= 150 mm.
3. Biconcave lens with focal length= 200 mm.
4. Biconcave lens with focal length= 250 mm.
5. Biconcave lens with focal length= 300 mm.

The biconcave lenses made of extra-white glass are also available with us.
