The NLIR-S2050 from NLIR are Mid-infrared Spectrometers that have an optical bandwidth of 2 µm - 5 µm. They have spectral resolutions of 6 cm-1, 3 cm-1 & 2.5 cm-1 with maximum readout rates of 400 Hz, 1.4E3 Hz & 130E3 Hz respectively. These vertically polarised spectrometers have a sensitivity of 130E3 counts/(ms µW) (S2050-400), 8E3 counts/(ms µW) (S2050-1k), and 1.6E3 count/(ms µW) (S2050-130k). They have a bit depth of 16 (S2050-400 & S2050-1k) & 12 (S2050-130k) and an exposure time of 10.8 - 1E6 µs (S2050-400), 9 - 1E6 µs (S2050-1k) & 1.3 - 654 µs (S2050-130k).
The NLIR-S2050 spectrometers are based on the NLIR upconversion technology. They have dark noise of 11 counts (S2050-400), 60 counts (S2050-1k) & 1 count (S2050-130k). These spectrometers require a minimum detectable power (in 100 ms) of 5 pW/nm (S2050-400), 75 pW/nm (S2050-1k) & 25 pW/nm (S2050-130k). They can be controlled via GUI & API interfaces and support SMA-905 fiber connector. These spectrometers are available in a module that measures 100 (H) mm x 306 (L) mm x 200 (W) mm and are ideal for optical coating measurement, 80 kHz mid-infrared spectroscopy, and kHz-rate optical coherence tomography applications.
