The broadest tunable QCL for mid-infrared spectroscopy
The latest MIRcat™ is the broadest tunable QCL system commercially available, marking a major advancement in mid-infrared spectroscopy. Building on over a decade of engineering innovation, MIRcat offers a tuning range of up to 1000 wavenumbers with 3 channels and 1400 wavenumbers with 4 channels. This advanced platform delivers exceptional tuning range, high sensitivity, and faster performance, making it perfect for cutting-edge analytical applications. MIRcat is designed to meet the evolving needs of modern spectroscopy with unmatched precision and efficiency.
Peak velocities up to 30,000 cm-1/s
The MIRcat adds high-speed tuning, higher spectral repeatability, improved thermal management, and longer-wavelength options to the first generation of the MIRcat laser, a field-proven multi-quantum cascade laser system. The MIRcat is truly a one-box, fully automated system with a flexible, modular design that allows factory configuration of up to four pulsed or continuous wave/pulsed modules, plus the option to add or upgrade modules later. The MIRcat offers a tuning range approaching 1000 cm-1 (> 6 µm) and wavelength coverage to > 13 µm. It also delivers unmatched, industry-leading performance in critical areas like peak tuning speeds of > 30,000 cm-1/s, output power up to 1 W, and TEM00 beam quality to enable high-efficiency fiber coupling. A new, higher-precision tuning mechanism and lower-noise drive electronics provide wavelength repeatability as high as < 0.1 cm-1 and CW RIN as low as -140 dBc/Hz.
