■Features●Emission wavelength: 4.33 μm (Typ.)●Output power: 20 mW (Min.)●Built-in aspherical colimation lens eliminates the need for optical alignment●Low-reflectivity beam exit window (ZnSe)
■Applications●Trace gas analysis (CO2, CO2 isotope)
■OutlineThe lens integrated package for DFB-CW type QCL is sealed and collimated housing. Internal lens provides collimated output beam radiation. TEC (peltier) and thermistor for temperature stabilization of QCL-laser chip are inside the housing. The lens integrated package allows to use under good usability without beam alignment of invisi-ble mid-infrared laser.
