Dewar Transmission/Reflection Accessory

Send to friend

Our Dewar Transmission/Reflection Accessory is useful for examining solid samples at temperatures ranging from -196°C to 350°C in a controlled environment. The cell is constructed of chemically resistant 316 stainless steel and features a K-type thermocouple for temperature measurement. A dewar is incorporated into this accessory for low temperature operation. For high temperature operation, low voltage heaters are provided for use in conjunction with an appropriate controller, like the Harrick Temperature Controller.

This accessory comes configured for transmission measurements, with a mount for the specified spectrometer. It can also be reconfigured for near-normal (12°) specular reflection with our Variable Angle Reflection Accessory.
