COPENHAGEN, Denmark, June 14, 2010 — Ibsen Photonics has announced the ROCK series of industrial grade, robust OEM spectrometers for the visible, short-wavelength near-infrared (SW-NIR) and near-infrared wavelength ranges. The instruments’ high optical throughput enables low-power sensing and fast spectral scans. The optical bench design allows for easy access to the detector, enabling customers to re-use their existing electronics for new equipment and thereby avoid expensive and time-consuming re-engineering. The spectrometers use proprietary holographic fused silica transmission gratings that provide 50% to 100% higher diffraction efficiency and lower stray light than traditional spectrometer gratings according to the company. The exclusive use of dielectrics in the optical path enables the spectrometers to be used in challenging environmental applications, including those at high temperatures. The visible model operates from 380 to 770 nm, has a numerical aperture of 0.22 and produces minimum resolution of 2 nm FWHM. Grating efficiency is >60%, stray light is <0.1%, and scan speed is 10 kHz. It operates from -10 to 45 °C and consumes 3 W. The SW-NIR version operates from 815 to 1065 nm, has a numerical aperture of 0.22 and produces minimum resolution of 3 nm FWHM. It has a USB 1.1 interface and an N-type metal oxide semiconductor cooled or uncooled detector. The near-infrared model operates from 1065 to 1870 nm, has a numerical aperture of 0.22 and produces minimum resolution of 6 nm FWHM. Temperature drift is <0.02 nm/°C, grating efficiency is >50%, and stray light is <0.1%.
