Edmund Optics has announced the availability of glass-substrate parabolic mirrors with off-axis focus for UV- and visible-spectra applications. Unlike conventional parabolic mirrors, these mirrors direct and focus collimated incident light at a fixed angle, providing full access to the focal point without blocking any of the incident beam, which simplifyies optical design and improves light-gathering in designs such as Czerny-Turner and Littrow spectrometer configurations as well as general collimator and beam-expander setups. The mirrors are fabricated from a soda-lime glass substrate and have their aspheric optical profile holographically recorded on the substrate. They are available in sizes ranging from 40 mm square to 65 mm square.

PRESS RELEASE
High-Performance Parabolic Mirrors Provide Off-Axis Focus
Edmund Optics (EO), the premier provider of optical components, today announced the availability of glass-substrate parabolic mirrors with off-axis focus for UV and visible-spectra applications. Unlike conventional parabolic mirrors, these direct and focus collimated incident light at a fixed angle, providing full access to the focal point without blocking any of the incident beam. This simplifies optical design and improves light-gathering in designs such as Czerny-Turner and Littrow spectrometer configurations as well as general collimator and beam expander setups.
EO's High Performance Off-Axis Parabolic Mirrors are fabricated from a soda-lime glass substrate and have their aspheric optical profile holographically recorded on the substrate. The rectangular mirrors offer either a ∏ l or a π l surface accuracy and are replicated from masters that have passed strict inspection criteria, including zonal interferrometric and Foucault testing.
The focal point location for off-axis mirrors can be characterized by the parent focal length and the y-offset - the dimensions along and at right angles to the incident beam axis. EO's mirrors are available with parent focal lengths of 125, 200, or 275 mm with y-offsets ranging from 53 to 85 mm. This leaves a clear aperture of 90% for superior light-gathering capacity. Parent focal length tolerance is ±0.15 mm and y-offset tolerance is ±2mm.

EO's High Performance Off-Axis Parabolic Mirrors are available in sizes ranging from 40mm square to 65 mm square. Prices start at $895. Please contact [email protected] for quantity pricing.
