An easily built thermostated sample cell holder for Raman spectroscopy is described. The apparatus, which uses thermoelectric heat pumps as heating and cooling elements, is characterized by a fast response and a temperature stability at the sample of better than ±0.1 °C over the −20° to 100 °C temperature range. The desired temperature can be either selected manually or controlled by computer.
