       Off-Axis Parabolic Mirrors are first-surface mirrors whose reflective surface is a part of the parent parabolic surface that is cut off from the parent parabolic plane and is designed to separate the focus so that the focus is outside the optical axis. They can focus collimated beams or collimated divergent light sources without chromatic aberration, and light reflected parallel to the central axis of the parabola will be concentrated in the focal point, while the reflective design eliminates the phase delay and absorption losses introduced by transmitted optics. The angle between the focusing beam and the collimating beam of the off-axis parabolic mirror is 90°, and the propagation axis of the collimating beam is perpendicular to the bottom of the base, so that the ideal focusing effect is achieved, so they are widely used in reflective optical systems, laser focusing systems, terahertz and other products and related fields.

Dimension-labs offers a wide range of off-axis parabolic mirrors (sizes and parameters can be filtered from the details below) and four reflective films (gold, silver, aluminum, and UV-enhanced aluminum) to meet your needs.
