50.8mm Dia. Off-Axis Parabolic Mirror, 101.6 mm FL, Prot AL - 400-2000nm Coating, 90 deg.

OPA-50.8-101.6-A90

OAPs (Off-Axis Parabolic) mirrors combine the achromatic and diffraction-limited focusing properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most optical systems. The reflected angle for this family is 90 degrees. Parabolic mirrors are aspherical and therefore ideally suited for use in optical instruments. They are free from spherical and chromatic aberrations, and thus focus the parallel beam to a point or point source to infinity. Each diameter is available in two focal lengths and two reflective metallic coatings. The back side of the mirror has threaded mounting holes and keying dowel pin holes for fixing location and orientation.
