Uniform Tunable Light Source with Expanded Spectral Range in a Compact Design
May 8, 2025 – San Diego, CA – Gamma Scientific, a global leader in optical metrology, announces the release of its SpectralLED® RS-9 Series, the latest evolution of its award-winning tunable light source platform. The RS-9 offers an expanded spectral range from 360 nm to 1000 nm, enabling precise spectral and color output from ultraviolet (UV) to near-infrared (NIR), including broadband whites, all within a form factor that is notably smaller and lighter than its predecessor.
The RS-9 integrates 34 discrete LED channels and 2 broadband white channels, including 4 UV channels below 400 nm, providing outstanding uniform illumination across a wide field of view (FOV). This platform is engineered to simulate application-specific lighting conditions with high precision, making it ideally suited for calibrating and testing cameras, image sensors, and light measurement instruments.
“The RS-9 addresses key customer requirements for automated sensor and camera calibration in environments where space and system efficiency are critical,” said Kong Loh, CEO of Gamma Scientific. “With a footprint that is one-third smaller and 50% lighter than our previous model, it integrates seamlessly into sensor test systems, motion stages, and optical benches. Its compact design, expanded UV coverage, and high spectral precision offer greater flexibility and faster deployment into laboratory and production workflows.”
Gamma Scientific’s SpectralLED® solutions comply with the latest standards established by the IEC and the International Committee for Display Metrology (ICDM), part of SID’s Definitions and Standards Committee. All RS-9 systems provide absolute NIST traceability and ISO/IEC 17025-accredited calibration to ensure measurement accuracy and compliance in critical test environments.
