Request InfoCoherent Inc.Coherent Inc. has released an upgraded controller for its laser spectrum analyzer system, which allows users to examine the details of the line spectra of CW lasers from 275 to 1625 nm. The controller incorporates a front-panel scan-voltage LED bar graph indicator, a 1X to 64X detector-gain-range selector, preset scan alignment selections for key wavelength bands and a centered sweep expansion function. The instrument is compatible with the company's model 240 and 216 analyzers and uses a 9-VDC input from a 100- to 240-VAC external power source.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2024 IssueAlexandrite LasersUnilase’s pulsed diode-pumped and compact CW alexandrite lasers operate at 760 nm and offer a variety of output power.
