HG-RadiSphere
Spectral Radiance Integrating Sphere System
High-Uniformity Integrating Sphere Structure · Spectral Radiance Output · Multi-Band Calibration Testing Platform
An integrating sphere radiometric calibration system engineered for spectral radiance calibration, remote sensing payload testing, and optical measurement fields.
Product Introduction
The HG-RadiSphere spectral radiance integrating sphere system is an optical radiometric calibration instrument designed on the principles of integrating sphere diffuse reflection homogenization. Utilizing a high-reflectivity integrating sphere cavity alongside a highly stable light source system, it delivers exceptionally stable radiance outputs. The system features a diffuse reflection coating layer inside its integrating sphere structure, achieving uniform light field generation through multiple internal diffuse scattering interactions. Coupled with stable precision driving power supplies, luminance control mechanics, and spectral calibration mechanisms, it significantly enhances the uniformity and stability of the radiometric output while effectively mitigating optical measurement errors to satisfy the stringent calibration needs of scientific research and industrial optical systems. The HG-RadiSphere supports multiple radiation output configurations, including UV, visible light, near-infrared, short-wave infrared, and broad-spectrum bands, allowing users to flexibly configure the source type, integrating sphere size, exit port aperture, and control modes according to specific application specifications.
Furthermore, the HG-RadiSphere spectral radiance integrating sphere system supports modular and highly customizable architectural designs. It can be seamlessly expanded for an array of application modes, such as spectral radiance calibration, camera response characterization, uniform light field testing, laboratory calibration of remote sensing payloads, and automated test environments. It is widely applicable to laboratory optical testing, aerospace remote sensing, industrial vision inspection, and scientific spectral analysis fields.
