TEL-TD45 Black Body Radiation Package
The TEL-TD45 Black Body Radiation Package includes the TEL-EG45 Radiometer, the TEL-EH10 Leslie's Cube, and the TEL-EH15 Stefan-Boltzman Source. Using the TEL-EG45, students can measure black body radiation from sources with a wide range of temperatures. Leslie's Cube (TEL-EH10) can be used as a source of black body radiation up to 120°C, while the different sides allow and investigation of emmissivity. The Stephan-Boltzmann Source can be used to investigate black body radiation from about 3000 to 3500 K.
- Sturdy with a broad range of sensitivity
The detector has a flat spectral response from 0.3 µm in the ultraviolet to 15 µm wavelength in the infrared. The detector area of about 2 mm² is small enough to measure the energy in a laser beam. For broad sources of radiation, the instrument is sensitive through a 60° cone angle.

Leslie's Cube can be used with the Radiometer TEL-EG45 to investigate thermal radiation as a function of temperature and surface finish.|
- Measure radiation as a function of temperature.
A low voltage power supply such as the TEL-33020 is also needed.
When used with the Radiometer TEL-EG45 the Stefan-Boltzmann Source lets one measure energy radiated as a function of temperature.
