Request InfoResearch Electro-Optics Inc. (REO)REO has launched linearly variable bandpass and edge filters for applications in spectrometry and temperature sensing. In these variable response coatings, the center wavelength of operation changes with position in a linear manner over the surface of the part. In the past, high manufacturing costs for these kinds of filters have limited their use to a few specialized applications. The company’s volume-scalable technology enables cost-effective production of linearly variable filters over a wide range of sizes. Bandpass filters are available for operation in the visible (380 to 760 nm),...See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2023 IssueSK-1300 Fused SilicaFused silica, the backbone of modern optical and semiconductor technologies, reaches new heights with Ohara's SK1300, setting industry standards for ultra-high purity, laser damage resistance, and...BioPhotonics Mar/Apr 2023 IssueCompact SpectrometersThe compact ROCK VIS and VIS-NIR spectrometers from Ibsen Photonics are designed for blood gas analysis.
