Request InfoIDEX Health & Science - Semrock Optical FiltersSemrock Inc. has launched StopLine, a 405-nm optical thin-film notch filter for flow cytometry, confocal microscopy and Raman spectroscopy. It blocks the laser line with an optical density of >6 and a notch width of <9 nm FWHM and provides greater than 90% transmission outside the notch. It rejects light by reflecting it, simplifying stray-light management. The filters are made with hard-coating technology and without any adhesives in the optical path. The combination of highly stable ion-beam sputtering technology with proprietary deposition control and software results in good optical...See full productRelated content from Photonics MediaPRODUCTSPromoted Content May 2022 IssueNew Wavelengths: 473 nm, 607 nm, 698 nmOxxius’ LaserBoxx family of DPSS laser / laser diode modules offers new wavelengths not readily available to the market: 473 nm (SLM) @ 50 mW, 607 nm @ 200 mW, and 698 nm @ 100 mW.
