  IR-519/301 Blackbody System

The IR-519 Radiation Source extends the temperature range of the IR-518 to 1200ºC. The length of the body is extended by 1". It can be used as a standard radiation source for the calibration of other laboratory sources, detectors, or other infrared devices requiring calibration against a standard.

The 20º tapered - recessed - cone, surface emissivity, and cavity aspect ratio combine to provide blackbody radiation by multiple reflection, absorption and re-emission of its thermal energy. The thermal energy of the cavity is provided by a ceramic-sealed heater coil that uniformly heats the cavity cylinder to temperatures from 50 º C to 1200ºC. The IR-519 is covered by a one-year warranty.
