Request InfoOptical Surfaces Ltd.KENLEY, England, Sept. 1, 2011 — Optical Surfaces Ltd. is offering planoconvex and planoconcave toroidal mirrors for pinpoint focusing in spectroscopic and imaging applications. These mirrors have two different radii whose axes are oriented at 90° to each other. They have advantages in applications where a beam must be focused and folded. Rather than requiring both a spherical and a plane mirror for this purpose, both functions are combined in one element. The lower number of optical elements increases energy throughput and enables more compact designs. Toroidal mirrors correct for the astigmatism that results when...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra July 2023 IssueMirror MountsWedged back paraboloid mounts from Optical Surfaces Ltd. provide a secure and stable platform for mirror diameters from 50 to 200 mm.
