However unlike a centered parabolic mirror an oap mirror has an advantage in that it allows more interactive space around the focal point without disrupting the beam as shown in.
Off axis parabolic mirror manufacturers.
One method involves using a rotating furnace to form the mirrors from a molten base material.
Some are made as off axis reflectors where the focal point is outside the incoming beam.
Moreover by folding the optical axis and displacing the focus away from the mechanical axis it is easier to install baffles to block stray light from.
Off axis parabolic reflectors off axis parabolic reflector diagram an off axis parabolic reflector achromatically directs a collimated beam of light to or from a focal point.
Compared with on axis parabolic or ellipsoidal reflectors the off axis mirrors do not have a central hole enabling light across the entire aperture of the mirror to be focused onto a detector.

Where to buy parabolic mirrors.
Buyer s guide products parabolic mirrors.
An off axis parabolic oap mirror is simply a side section of a parent parabolic mirror.
Mirrors with a parabolic shape exhibits the lowest possible aberrations for certain optical purposes such as tightly focusing a collimated laser beam.
The top countries of suppliers are india china and india from which the percentage of parabolic mirror supply is 1 98 and 1 respectively.
Manufacturers can produce off axis parabolic mirrors in several ways.
They are designed to focus or collimate broadband light.
