DUNEDIN, Fla., Sept. 26, 2011 — To maintain thermal stability of spectrometers operating in variable environments, Ocean Optics Inc. has released the USB-TC small-footprint heating device. Compatible with its USB2000+ and USB4000 miniature spectrometers, the new unit attaches directly to the spectrometer and maintains wavelength thermal stability to within ±0.025 pixels/ºC. This temperature control ensures accuracy in industrial and other settings where temperature variations can affect spectral performance. The device is available with preselected set point temperatures between 25 and 55 ºC and comes with a 12-VDC, 3-A power supply. With constant ambient temperature, it stabilizes to within 0.1 ºC of the final temperature within 30 min of power-up. The system will operate in temperatures ranging from 5 to 40 ºC below the set point. The USB2000+ and USB4000 spectrometers’ small-footprint, high-speed CCD array design and modular optical bench accessories (entrance apertures, order sorting filters) enable their configuration for hundreds of applications. The USB-TC is available with new spectrometer purchases or as a retrofit option for owners of USB2000+ and USB4000 spectrometers.
