Ocean Optics has released the USB-TC small-footprint heating device for maintaining the thermal stability of spectrometers operating in variable environments.
Compatible with Ocean's USB2000+ and USB4000 miniature spectrometers, the unit attaches directly to the spectrometer and maintains wavelength thermal stability to within +/-0.025 pixels/ºCelsius. The USB-TC is available with pre-selected set point temperatures between 25 and 55ºC and comes with a 12VDC, 3A power supply.
With constant ambient temperature, the USB-TC stabilises to within 0.1ºC of the final temperature within 30 minutes of power-up. The system will operate in temperatures ranging from 5 to 40ºC below the set point temperature. The USB-TC is available with new spectrometer purchases or as a retrofit option for existing owners of USB2000+ and USB4000 spectrometers.
