64biits) USBtwoHamamatus Photonics supercontinuum mid infrared quantum cascade laserIt is a product launched by Hamamatsu, JapanExternal cavity structure quantum cascade laserIt has been validated by the market. Effective wavelength range8-10um, with a power of up to20.9W, possessingStandard output mode:QCLOperation signal output and
MEMSOperation signal output.Hamamatsu, Japan8-10umMid infrared broadband quantum cascade laserIt is a pulsed quantum cascade laser that achieves wide wavelength scanning through an external cavity structure. It can remotely measure mid infrared spectra, is non-contact, and has high throughput. Compared to traditional
FT-IRDifferent from mid infrared spectroscopy technology, this product provides new value: high output and high wavelength resolution.Mid infrared quantum cascade laserThe system structure is as follows: including a broadband gain medium coated with an anti reflective film, non spherical mirrors on both sides, and
MEMSGrating, laser is emitted from one side of the non spherical mirror.The schematic diagram of gas detection is as follows. contain
