Request InfoYokogawa Europe BVThe Yokogawa Test & Measurement Div. has announced the AQ6373, an optical spectrum analyzer that measures from 350 to 1200 nm. It features a color analysis function that renders it suitable for measuring LEDs and laser light sources. Wavelength accuracy is ±0.5 nm, wavelength resolution is down to 0.01 nm, and sensitivity is –80 dBm. Standard sweep time is 1 s, and 0.5 s in automatic mode. The free-space optical input makes the instrument suitable for use with single-mode, multimode and large-diameter-core fibers. A built-in light source aids optical alignment. The 10.4-in. bright display...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2022 IssueOptical Spectrum AnalyzersThe AQ6375E and AQ6376E optical spectrum analyzers from Yokogawa Europe BV, Test & Measurement combine short- and mid-wavelength IR with extreme optical precision to aid in the development of...Photonics Spectra October 2022 IssueExplosion-Proof TDL SpectrometerAn explosion-proof TDLS8200 probe-type tunable diode laser spectrometer from Yokogawa Electric Corp. provides simultaneous measurement of oxygen and carbon monoxide or methane concentrations for...Photonics Showcase June 2022 IssueIndustrial Laser Power SensorThe Ophir® IPM-10KW high-power modular laser power sensor delivers high-accuracy, repeatable measurements in rough production environments.
