Request InfoLambda Research Optics Inc. (USA)VeLo15 is an antireflection coating produced by Lambda Research Optics Inc. and available in all standard focal length and edge thickness configurations of 1.5- and 2.0-in.-diameter ZnSe focusing lenses. Benefits include reduced setup time because of the minimized thermal lensing effect, enhanced cutting performance and transmission of the red 650- to 670-nm laser line for easy alignment. Typical total absorption is <0.15%, and scratch-dig surface quality is 40-20 on both sides. The company also offers VeLo15 coating service on customer-supplied lenses, with quick delivery turnaround and...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/27/2024Fiber Metalization SystemThe Midas Metalization System from Intlvac is designed to produce a single or multilayer symmetrical metal coating on ends, mid spans, or windows of optical fibers for use in a hermetically sealed...Photonics Showcase January 2023 IssueIR and Patterned FiltersDSI designs and manufactures bandpasses, beamsplitters, ARs, and absorption coatings for use in the MWIR through LWIR wavelength regions, customized to specific applications.
