Request InfoOZ Optics LimitedOz Optics Ltd. has introduced polarization-maintaining (PM) fiber pigtailed laser diode stable sources in two versions: PM fiber pigtail and receptacle. The units comprise a laser diode, PM fiber assembly, laser diode driver electronics and power supply. They have a wavelength range from 635 to 1550 nm. The pigtail version offers extinction ratios of 20 and 30 dB, and the receptacle version comes with a l/4 plate and polarizer plate on a rotary platform for 35-dB extinction ratio coupling into the fiber. Peltier-cooled sources also are available.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra February 2024 IssueFiber-Coupled LEDThe Model X3312 from LumeDEL LLC is a fiber-coupled LED that can be used for applications in spectroscopy as a replacement for halogen lamps.
