Spectrally resolved line detector in the infrared range 1050-2200 nm

Summary

The tender concerns the purchase of a spectrally resolved line detector for infrared spectroscopy in the 1050-2200 nm range for scientific work at Friedrich-Schiller-University Jena. The detector must meet minimum technical specifications including 0.2 nm spectral resolution, quantum efficiency thresholds, 25 x 250 μm pixels in a 1024 x 1 linear array, detector cooling, low dark current and readout noise, detector nonlinearity below 1%, spectrometer resolution below 0.2 nm at 1550 nm, wavelength repeatability of 0.1 nm and accuracy of 0.2 nm, stray light below 5e-4 at 1 nm, and a spectrometer with an input and two outputs. The system must include motorized slit input and shutter, a motorized grating turret, a monochromator with at least 500 mm focal length, and data acquisition/analysis software compatible with Windows 11 with a Python interface; power supply 220 V. Delivery and installation take place at the university institute in Jena; the contract covers delivery free on-site with packaging; installation and on-site initial instruction for at least two staff; warranty for at least 12 months; spare parts available for at least five years; EU service; the project budget is up to 110,000 EUR net and delivery within 18 weeks. The contract will be awarded as a single lot; details are provided in the tender documents (Annex 2).
