Package with a built-in lens improves ease-of-use The lens-integrated package for DFB-CW type QCL has a sealed and collimated housing. The internal lens provides collimated output beam radiation. TEC (peltier) and thermistor for temperature stabilization of the QCL-laser chip are inside the housing. The built-in lens makes the QCL easy to use, eliminating the need for beam alignment. Difference from previous products Contains a collimation lens with no change in package size. Needs no additional collimation lens (A11331 sold separately). Features „ „ Built-in aspherical collimation lens eliminates the need for optical alignment „ „ Light output: 20 mW (min.) „ „ Low-reflectivity lens and window Application „ „ Trace gas analysis L12004-2310H-E, L12005-1900H-E, L12006-1631H-E DFB-CW QCL (built-in lens) Type No. Wavelength Wavenumber Target gas L12004-2310H-E 4.33 µm 2,310 cm -1 CO 2 , CO 2 isotope L12004-2190H-E 4.57 µm 2,190 cm -1 N 2 O, CO L12005-1900H-E 5.26 µm 1,900 cm -1 NO L12006-1631H-E 6.13 µm 1,631 cm -1 NO 2 DFB-CW QCL Type No. Wavelength Wavenumber Target gas L12004-2310H-C 4.33 µm 2,310 cm -1 CO 2 , CO 2 isotope L12004-2209H-C 4.53 µm 2,209 cm -1 N 2 O L12004-2190H-C 4.57 µm 2,190 cm -1 N 2 O, CO L12005-1900H-C 5.26 µm 1,900 cm -1 NO L12006-1631H-C 6.13 µm 1,631 cm -1 NO 2 L12007-1392H-C 7.18 µm 1,392 cm -1 SO 3 L12007-1354H-C 7.39 µm 1,354 cm -1 SO 2 L12007-1294H-C 7.73 µm 1,294 cm -1 CH 4 DFB-Pulsed QCL Type No. Wavelength Wavenumber Target gas L12014-2231T-C 4.48 µm 2,231 cm -1 N 2 O, CO, CO 2 L12015-1901T-C 5.26 µm 1,901 cm -1 NO L12016-1630T-C 6.13 µm 1,630 cm -1 NO 2 L12017-1278T-C 7.82 µm 1,278 cm -1 CH 4 , N 2 O L12020-0993T-C 10.07 µm 993 cm -1 NH 3 LASER PRODUCTS CW Quantum Cascade Laser L12004-2310H-E, L12005-1900H-E, L12006-1631H-E ND Inspection Industry Security Optical Comms Semicon Prod.
