Request InfoIDEX Health & Science - Semrock Optical FiltersMaxDiode cleanup filters have been announced by Semrock Inc. for use with laser diodes. They clean up the laser output by stripping it of undesired noise, leaving only the desired laser line. They achieve 90% transmission over a defined range of each diode’s possible wavelength and offer a nearly square passband. Their steep edges transition to high blocking to eliminate out-of-spectral-band noise. The filters are made with ion-beam-sputtering technology, and proprietary “no burn out” hard coating increases reliability. Available filters are tailored to 635-, 440- and 405-nm diode lasers,...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 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...Photonics.com 10/24/2023Computer Generated HologramThe 9-inch computer-generated hologram (CGH) from Arizona Optical Metrology enables snapshot metrology of up to 7-inch diameter convex optics.
