Optical lenses, excellent for physics classroom demonstrations in optics and light refraction.
- Spherical lenses made of high quality, optically worked glass
- Highly polished, with ground edges
- Includes 3 biconvex and 3 biconcave lenses
- Focal lengths of 200, 300 and 500 mm
- Sets available in three diameters: 1.5, 2 and 3"
These lens sets are made of highly polished, optically worked glass with ground edges for safe handling. Three double convex lenses have converging focal lengths of 200, 300 and 500 mm. Three double concave lenses have diverging focal lengths of 200, 300 and 500 mm.
