Biconcave Lens / Double Concave Lens Diameter 50mm, FL- 5cm / 10cm / 15cm / 20cm / 25cm / 30cm / 100cm
RM 5.50
1. Unmounted spherical lenses suitable for use with optical benches and for other studies in the optics.
2. Spherical optically worked glass, with polished faces and ground edges.
These lenses are symmetrical with equal radii on both sides. The biconcave lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination with other lenses.
