Pairs of cylindrical lenses can be used to circularize and collimate the output of a laser diode. Features n Mounted in T Black, Anodized, LaserEngraved Lens Cell tc n Focal Lengths fromWD 50 to 1000 mm These lenses have the added advantage that they are epoxied in an engraved cell n Uncoated and Broadband AR-Coated to allow for mounting in our SM1 Lens Tubes or any Ø1" Lens Mounts. The cell is black anodized and engraved with the part number, focal length, and Versions Ø21.0 mm coating information (if applicable). The wall thickness is designed to allow fullØ23.4 mmn SM1 Lens Tube Compatible (Ø0.92") (Ø0.83") contact when using an SM1RR retaining ring to hold the lens. All of our round n Enable Magnification in One Dimension R cylindrical lenses can be ordered uncoated or with one of three broadband AR n Use in Pairs to Collimate and Circularize coatings. These high-performance, multilayer AR coatings have an average the Output of a Laser Diode reflectance of less than 0.5% (per surface) across the specified wavelength ranges and are designed for use with angles of incidence between 0 and 30 degrees. f Windows T Diffusers tc Ø25.4 mm (Ø1.00") WD Ø23.4 mm (Ø0.92") Ø21.0 mm (Ø0.83") R Please refer to our website for complete models and drawings. f Standard Broadband AR CoatingsØ25.4 mm (Ø1.00") These lenses are also available with one of our three standard broadband antireflection coatings. To order the lens with an AR Coating, add the coating code to the Item #, and then add the coating cost to the lens price.
