Request InfoThorlabs Inc.Thorlabs has released the first product in a planned line of optical spectrum analyzers (OSAs). While many commonly available models are grating-based monochromators, this version uses a Fourier transform OSA with a scanning Michelson interferometer configuration. The result is a device that operates as both a full-featured OSA and a high-precision wavelength meter. It features a 1000- to 2500-nm wavelength measurement range, spectral resolution of 7.5 GHz when used as an OSA, and wavelength meter resolution of 0.2 pm. The input aperture accepts FC/PC-terminated fibers, suitable for...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueRaman SpectrometersThe RASP1 and RASP2 Portable Coded-Aperture Raman Spectrometers from Thorlabs Inc. are designed for detecting low-intensity Raman signals and can analyze the chemical composition of solid and liquid...Photonics Spectra February 2023 IssueHolographic Grating SpectrometerThe HG10 Holographic Grating Spectrometer from Thorlabs Inc. is a fiber-based, high-speed device that provides sub-nm resolution in the 810- to 965-nm optical range.
