HG-BB-C Series
Cavity Blackbody Radiation Source
High-Emissivity Cavity Structure · Fine Temperature Control · Wide Temperature Range
A cavity blackbody radiation source system engineered for infrared radiation measurement, spectral radiation calibration, and temperature calibration fields.
Product Introduction
The HG-BB-C series cavity blackbody radiation source is an infrared radiation equipment designed based on blackbody radiation theory. By utilizing a high-emissivity deep cavity structure and a precision temperature control system, it achieves a stable, traceable thermal radiation output. The equipment provides infrared radiation closely approaching ideal blackbody characteristics across a wide temperature span, acting as an accurate radiation reference for infrared thermal imagers, infrared detectors, spectral radiometers, and remote sensing instrumentation.
This series features a geometric cavity design that exploits the principle of multiple internal reflections to increase the effective radiation emissivity. Combined with stable isothermal control and a multi-point temperature feedback calibration mechanism, it achieves uniform temperature distribution across the cavity alongside long-term output stability, effectively minimizing radiation errors and enhancing measurement and calibration precision. The equipment supports continuous temperature adjustment, automated closed-loop temperature maintenance, and multiple aperture specifications to satisfy the calibration requirements of infrared systems with varying wavebands and spatial resolutions.
The HG-BB-C series cavity blackbody radiation source is widely applicable to infrared temperature measurement calibration, remote sensing payload calibration, infrared imaging testing, radiation metrology laboratories, and aerospace optical testing fields.
