BARRINGTON, N.J., June 19, 2013 — Edmund Optics’ TechSpec C-Mount Achromatic Pairs relay lenses feature an integrated iris that allows users to adjust the numerical aperture and depth of focus. The lenses are designed for a variety of OEM imaging applications, including relay and projection. The aluminum housing surrounding each lens pair eliminates the risks associated with handling loose optics. C-mount threading on each end facilitates mounting and alignment, and integration into the optical system. The lenses provide a broadband visible coating for high transmission and low reflection over a wide spectral range. They are offered in eight models, in 1:1, 1:2 and 1:3.33 magnifications, from 30- and 30-mm focal lengths to 100- and 100-mm focal lengths. The C-mount barrel is available without premounted lenses for customized magnification pairs.
