Blackbody Calibration Sources

SW40

Brief description

With its Ø 40 mm aperture, the SW40 liquid bath blackbody is designed for calibrating thermal imaging cameras and Infrared Radiation Thermometers. The cavity is heated with high uniformity by the surrounding circulating liquid and has a high temperature stability with an optimal emissivity.

Features
  • Cavity aperture: Ø 40 mm
  • Temperature non-uniformity: ΔT < 0.2 K
  • Temperature range: -20 … 110 °C

 

SW 15

Brief description

The SW15 is used as a portable or stationary blackbody that has a fixed set-point temperature. 100 °C is the standard radiator temperature.

Features
  • Portable blackbody for calibration on site
  • Standard Radiator temperature: 100 °C
  • Optional temperatures on request
