Request InfoResearch Electro-Optics Inc. (REO)Research Electro-Optics (REO) Inc.’s high-performance aspheric lenses are fabricated from CaF2, ZnSe and ZnS substrates. The lenses offer a combination of benefits for applications that require broadband or multispectral operation from the visible through the infrared, including military rangefinding and target designation. Benefits include high surface accuracy of approximately λ/4 at 633 nm to achieve small focused spot sizes; low surface roughness of 40 to 50 Å rms for minimal scatter and loss; and sophisticated, multilayer thin-film coatings. The coatings offer...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jan/Feb 2023 IssueZinc Selenide OpticsHigh-quality zinc selenide (ZnSe) lenses, output couplers, and mirrors from Laser Research Optics are optimized at 1.06 μm for medical laser OEMs. The devices are manufactured to...Photonics Spectra September 2022 IssueMWIR Continuous Zoom LensThe Ophir® LightIR 18- to 225-mm MWIR f/4 continuous zoom lens from MKS Instruments Inc. is a compact thermal imaging lens optimized for 10-µm SXGA/HD and 15-µm VGA focal plane array...Vision Spectra Summer 2023 IssueSwir LensThe Ophir LightIR 10-135 mm and 18-225 mm MWIR f/3.6 continuous zoom lenses from MKS Instruments Inc. are compact, high-performance, motorized continuous zoom lenses.
