LRS‑455 6” Integrating Sphere Luminance Calibration Standard
Part Number: 6000-0014-10
LRS-455-6-1 6″ Integrating Sphere
A NIST‑traceable, self‑contained integrating sphere light source delivering highly stable luminance, correlated color temperature, and spectral radiance for accurate photometer and spectroradiometer calibration—available for visible or near‑infrared measurement needs.
Why use the LRS‑455 for calibration?
- Provides a highly uniform, stable luminance reference for precise photometric and spectroradiometric calibration
- Delivers traceable confidence with NIST‑referenced uncertainty across luminance, color temperature, and spectral radiance
- Supports both visible and near‑infrared calibration workflows through configurable filter and spectral options
