Discover a diverse range of spectral radiance and irradiance reference sources, including broadband, narrowband, and spectrally tunable options. Spectra-FT fine tunable LED light sources are ideal for testing cameras and optical sensors response to multiple illuminants, to spot illumination.

Finding a consistent source with enough blue content has been a challenge – until now. The high power in the blue region is matched with high temporal stability, and a smooth visible spectrum for long-term testing that minimizes spectral mismatch.

Use night sky spectrums and levels for instrument verification. Combine sources or filter sources to suit the test needs. Today’s night vision systems are challenging not only visible ranges but extending to the SWIR for enhanced performance and sensor fusion. COLOSUS dynamic range can cover day levels and night levels continuously in one system.
