ISS-30-TLS – a next-generation spectrally tunable multi-LED light source

25/09/2025

Our partner Gigahertz-Optik is introducing the ISS-30-TLS – a next-generation spectrally tunable multi-LED light source.

They’re excited to share one of our latest system configurations:
✔️ 300 mm Ø integrating sphere with 100 mm output port
✔️ BaSO₄ coating with spectral reference sensor (CSS-45)
✔️ User-friendly software for spectral tuning and system control
✔️ Luminance & spectral radiance calibration included

The ISS-30-TLS delivers:
✔️ Uniform field of view & high dynamic range
✔️ Flexible configuration – up to 48 LEDs for advanced spectral tuning
✔️ Applications in spectroradiometer calibration, HDR testing, imaging & non-imaging device calibration, and pixel alignment
✔️ Certified, traceable calibration of luminance, spectral radiance, and color temperature (ISO 17025 compliant)

Thanks to its RGBW LED design, a wide range of CCTs is possible, making the ISS-30-TLS a versatile solution for precision optical testing and calibration.

💡 Whether you need a reference standard for spectral radiance or a high-performance tool for advanced imaging calibration, the ISS-30-TLS adapts to your requirements.
