Unlike conventional parabolic mirrors, the new offering simplifies optical design and improves light-gathering.

Edmund Optics has introduced its glass-substrate parabolic mirrors with off-axis focus for UV and visible-spectra applications.

According to the company, 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.

Edmund Optics’ 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 1/2λ or a 1/4λ surface accuracy and are replicated from masters that have passed strict inspection criteria, including zonal interferrometric and Foucault testing.
