ALTERNATIVE INSTRUMENTS from UDTi

In addition to optometers, for building modular photosensor systems, UDTi and Gamma Scientific offer colorimeters and spectroradiometers, instruments which combine dedicated photosensor arrays with sophisticated electronics. These integrated sensing instruments may be substituted for simple photometer and radiometer subsystems to add multidimensional colorimetric and spectral analysis capability for any light-measurement application.

Options from UDT Instruments: SLS9400 FPD Colorimeter Handheld instrument for contact or non-contact measurement of display luminance and color. Adaptable for LED and illumination applications.   Options from Gamma Scientific: RadOMA Series Spectroradiometers  Industry-proven high-performance spectral engine. Backside-thinned CCD array; TE-cooled; 16-bit A:D; USB interface; TTL trigger; 4 different spectral ranges to choose from.

Enhanced capabilities include:

Spectroradiometry:

• Spectral Flux (W/nm)
• Spectral Irradiance (W/m²/nm)
• Spectral Intensity (W/sr/nm)
• Spectral Radiance (W/m²sr/nm)

Spectral Analysis:

• Spectral Power Distribution (SPD)
• Spectral Intensity Distribution
• Peak Wavelength
• Spectral Bandwidth (FWHM)

Colorimetric Analysis:

• Chromaticity
• CCT (Correlated Color Temperature)
• CRI (Color Rendering Index)
• Dominant Wavelength & Purity
