Request InfoWavelength ReferencesWavelength References will introduce a low-cost miniaturized hydrogen cyanide gas that it says provides asolute accuracy of HCN gas lines better then 0.1 pm and is directly NIST traceable. These lines cover the entire C-band. Wavelength references also offers gas cells of all types as well as lasers locked to gas absorption lines. It will also introduce a locker box that can be used to lock a tunable laser to any gas line in the built-in gas cell(s). The box can also be used to calibrate the laser against the built-in gas cells.See full productRelated content from Photonics MediaPRODUCTSPromoted Content April 2024 IssuePhotonic Solutions from UV to IRDaylight Solutions, a commercial portfolio under Leonardo DRS, designs and manufactures high-precision laser and photonics engines that operate throughout the ultraviolet, visible, near-infrared, and...Photonics Spectra January 2024 IssueCompact PhotorelayThe TLP3476S photorelay in the S-VSON4T package from Toshiba Electronic Devices & Storage Corp. offers a high-speed turn-on time, helping to shorten test time for semiconductor testers.
