Bi-Concave Spherical Lens
Bi-Concave Spherical Lens have negative focal length and the same radius of curvature on both sides of the lenses. Built with two concave surfaces and can function similarly to Plano Concave Spherical Lens by causing collimated light to diverge. Designed for beam expansion, image reduction, or light projection applications, they are also ideal for expanding the focal length of an optical system.
Our lenses have been fabricated with different types of materials, namely BK7 and Fused Silica.
