![]() Infrared Unleashed NLIRHirsemarken 1 3520 Farum Denmark See us at LASER World of Photonics 2025 in Munich, June 24–27 (booth A3.218)! | ![]() NLIR's SPEKTRUM Wavelength Converter efficiently converts wavelengths from 1.9 – 5.3 µm in the mid-infrared to 682 – 886 nm in the visible/near-infrared (VIS/NIR). This conversion is simultaneous and does not require time lag or scanning elements. The output is compatible with standard fiber-coupled grating spectrometers or silicon-based sensors. NLIR's TUNE Wavelength Converter is optimized for high conversion efficiency within a narrow bandwidth, ideal for sensitive mid-infrared light measurements. It operates over a tunable range from 2.7 – 4.3 µm, with the converted light shifted to 763 – 853 nm, suitable for any fiber-coupled detector operating in these near-infrared wavelengths. The TUNE Wavelength Converter is particularly effective for detecting narrowband signals, whether weak or rapidly varying. It supports measurements with time-gated PMT, SPAD detectors, APDs, and high-speed PIN photodiodes. Now you can read mid-infrared data with your VIS/NIR spectrometer/detector.
