Request InfoTempotec Optics Co. Ltd.Tempotec Optics Co. Ltd. now fabricates colored glass filters of various types: the cutoff, which blocks the short wavelength by absorption and transmits the long wavelength; the selective absorption, which transmits or absorbs one or several wavelengths; and the neutral density version, which provides a similar level of absorption for the full visible wavelength range. The filters are available in circular or rectangular shapes up to 200 mm in size. They offer surface quality of typically 60/40 and up to 40/20, flatness of typically λ/4 and up to λ/10, and parallelism of <30...See full productRelated content from Photonics MediaPRODUCTSPromoted Content August 2022 IssueNew Filters Enable Compact, Lower Cost FluorometerDelta Optical Thin Film has introduced new advanced excitation and emission bandpass optical filters for fluorescence spectroscopy/microscopy that enable more compact and lower cost fluorometers to...Promoted Content February 2023 IssueCustom WL Selective Optical FiltersIridian Spectral Technologies designs and manufactures wavelength selective optical filter solutions providing “more signal, less background”, customized to meet the technical and...Promoted 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...Promoted Content March 2024 IssuePrecision Polished SubstratesOhara is a world-class manufacturer of high-quality double-side lapped and polished substrates suitable for use at 248 nm.
