Off-Axis Parabolic Mirrors for Imaging Applications

Off-Axis Parabolic Mirrors for Imaging Applications

Optical Surfaces Ltd is a leading international manufacturer of Off-Axis Parabolic Mirrors (OAPs) for demanding imaging applications. Off-axis parabolic mirrors can be a useful tool in optical design. OAPs combine the achromatic and diffraction limited imaging properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most imaging systems. OAP's offer the ability to focus collimated light without introducing spherical aberration. Additionally, unlike ...

Parabolic Mirrors for Optical Instruments

Parabolic Mirrors for Optical Instruments

Optical Surfaces Ltd is a leading manufacturer of Off-Axis Parabolic Mirrors for optical instruments including radiometers, MTF measuring systems and spectrometers. Off-axis parabolic (OAP) mirrors are the most common type of aspherical mirrors used in optical instruments because they are free from spherical aberrations, and can focus a parallel beam to a point or point source to infinity. Employing off-axis parabolic mirrors in an instrument design allows optical engineers to not only ...
