Request InfoIDEX Health & Science - Semrock Optical FiltersTailored for 405-, 440-, 470- and 635-nm commercially available diode lasers, the MaxDiode cleanup filters offer 90% transmission over a defined range of each diode’s expected wavelengths. Available from Semrock Inc., they have extremely steep edges, which result in high blocking to filter out the out-of-band spectral noise, leaving the desired laser line. Their square low-ripple passbands help maintain consistent output power as the wavelength varies from laser to laser, as the laser ages or as the temperature changes. The thin-film filters are suitable for spectroscopic applications,...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 6/15/2023Water Disinfection SystemThe PearlAqua Micro A UV-C LED water disinfection system from AquiSense Technologies deploys patented reactor technology and high-volume manufacturing capabilities into a small footprint for...Photonics.com 5/25/2022Flow Cytometry ReagentsRealYellow™ 586 Reagents from Becton, Dickinson and Co. enable researchers to gain improved data resolution and greater insights from samples compared to traditional fluorochromes. ...BioPhotonics Jul/Aug 2022 IssueOptical Parametric OscillatorThe 17OPO-1-50 S Optical Parametric Oscillator from AMS Technologies AG generates short laser pulses for applications in the field of photoacoustic imaging.
