Request InfoMeadowlark Optics Inc.FREDERICK, Colo., June 27, 2013 — Meadowlark Optics Inc.’s liquid crystal technology for polarization control now extends into the midwave infrared (MWIR), enabling its standard line of polarization controllers to be used for its variable retarders. The liquid crystal-based retarder allows manipulation of polarization states without moving parts in the 3.6- to 5.7-μm region, providing λ/2 retardance (or greater) up to 5.7 μm. Substrate material is antireflection coated germanium. Reflectance is ≤5% per external surface, operating temperature range is 0 to 50° C and response time is...See full productRelated content from Photonics MediaPRODUCTSPromoted Content May 2022 IssuePhaseCam MWIRThe PhaseCam MWIR is a dual-port, midwave infrared interferometer that measures optical surface shape and wavefront error at a 3.39 µm infrared wavelength with incredibly fast acquisition for...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.
