Request InfoIDEX Health & Science - Semrock Optical FiltersSemrock Inc. has introduced three thin-film filters to be used with 325-nm HeCd, 473-nm argon-ion or doubled Nd:YAG, and 1064-nm Nd:YAG lasers in Raman spectroscopy. The ultrasharp long-wave pass filters rely on ion-beam sputtering technology and the company's proprietary manufacturing tools to block the laser line with optical density of ≥=6, and they transmit the wavelengths that are only 1% longer than the laser line. The company says the performance of these Raman edge filters is highly reliable and stable.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.
