On-Axis Parabolic Mirrors

Optical Surfaces Ltd. offers a complete manufacturing and test capability to produce On-Axis Parabolic Mirrors up to 600mm (24-inches) in diameter. All on-axis parabolic mirrors are manufactured to customer specifications and are supplied with full surface quality test data. Parabolic mirrors are the most common type of aspherical mirrors used in optical instruments. They are free from spherical aberrations, and thus focus the parallel beam to a point or point source ...
