MSE supplies offers customized Spherical Mirrors with different materials, dimension, surface qualify, etc.

Spherical mirrors include concave spherical mirrors and convex spherical mirrors. The reflecting surface of the former is on the outside of the sphere while it is on the inside of the sphere for the latter. Concave spherical mirrors can converge collimated light into a spot or changing the spot source to collimated light. Convex spherical mirrors can expand the incident beam. They are basic optical elements in various optical systems.

MSE Supplies can offer a variant of optical elements, with different materials, size, surface quality and coating. Please contact us for customization or bulk orders.
