Request InfoMKS/Spectra-PhysicsDesigned for powering bioinstrumentation, a new direct diode laser from Spectra-Physics (a Newport company) has a bandwidth at least three times narrower than conventional 488-nm direct diodes. The Excelsior One NB 488-50 has a laser-to-laser center wavelength variation of <±1 nm and outputs up to 50 mW at 488 nm. It also features a typical full width at half maximum (FWHM) linewidth of <0.5 nm and low noise of <0.5 percent root mean square. Suitable for fluorescence-based applications such as flow cytometry, confocal microscopy and multiarray readers, its narrow-bandwidth...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...BioPhotonics Jul/Aug 2023 IssueVCSEL Laser DiodeThe single-mode 850-nm vertical-cavity surface-emitting laser (VCSEL) diode from IMM Photonics GmbH is contained in a compact TO46 housing.
