Spectra-UT Ultra Tunable Spectral Calibration Sources

Building on our experience with solid-state tunable light sources, Spectra-UT Ultra Tunable Spectral Calibration Sources use a continuous-spectrum light source and polychromator technology to offer incomparable control over generated spectral waveforms. 

Spectra-UT Sources can reproduce complex spectral features with a precision that enables high-resolution simulation of standard illuminants as well as natural or synthetic sources and emissions. Spectra-UT is a uniform source for flat-fielding applications and can be adapted to optical light guides and collimators for remote sample spectral illumination.

Spectra-UT is capable of producing a near-perfect match to almost any target spectral waveform in the visible-light region by using a sophisticated spectral matching algorithm. It can render narrow-band targets on the order of 10 nm full-width half-max, broad VIS spectra and complex shapes.
