Abstract:
An improved optical chamber is described containing a Chatelain prism with controlled heating and temperature control. It consists of placing the prism between two copper plates heated through a miniaturized device that creates a hot air current inside a small acrylic chamber. The heater is a power transistor controlled by an operational amplifier that creates a 3 h ramp generated digitally through firmware in a microcontroller. The cell temperature, obtained through a thermistor, can be controlled to ±0.1 K. © 2005 American Institute of Physics.
