Request InfoAltechnaAltechna has released a line of elliptical flat mirrors ranging in size from 12.7 to 50.8 mm whose apertures become circular when the mirror is rotated 45° around the minor axis. The mirrors are available in four types of metallic coatings: aluminum, which provide reflection in the UV, visible and mid-IR wavelength ranges; protected silver, which provide the highest reflectivity in the visible range; protected gold, which are efficient in the IR range; and dielectric coated, which provide high reflectivity.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2024 IssueMirror MountsThe OS series of large-diameter mirror mounts from Optical Surfaces Ltd. provides a secure platform for larger, high-precision flat, off-axis, and spherical mirrors.
