Off-Axis Parabolic Mirrors

Off-Axis parabolic Mirrors

Spectrum Scientific’s off axis parabolic (OAP) mirrors eliminate aberrations that are present when trying to use spherical mirrors in off axis conditions. OAP mirrors ensure high resolution in compact design systems and are key elements in spectrometers as well as astronomical optical instruments. OAP mirrors feature light weight monolithic designs which can incorporate mounting features onto the mirror itself.

OAPs are achromatic focusing on collimation and have low scatter for UV applications. Spectrum Scientific offers optimized coatings for the deep UV as low as 120nm as well as coatings to suit VIS, NIR and IR.

Our OAPs can be replicated onto a range of materials including glass, metal, invar and silicon carbide.

In addition to custom manufactured mirrors, Spectrum Scientific offers a range of standard mirrors. If we do not have a mirror that meets your requirement, please contact our sales department as new mirrors are manufactured on a regular basis.
