Spectral & Viewing Angle characterization

Standard color measurements, even if perfectly adjusted to the human eye sensitive, are quite restrictive compared to the complex spectral stimuli always emitted by any king of display. A multispectral analysis with 20 to 30 channels in the visible range can be helpful. For digital color imaging and color reproduction this approach has been used with success. Some attempts have been made recently to characterize backlights with hyper-spectral camera. Transmission of display components such as polarizer and diffusion films, can exhibit complex spectral behaviors that need to be taken into account for precise predictions of the emissive properties.

A complete solution for full spectral & polarization measurement

ELDIM's ELDIM's EZContrastMS is an extension of the well known Fourier transform EZContrast viewing angle instruments proposed by ELDIM for more than 10 years to measure luminance and color. One of ELDIM for more than 10 years to measure luminance and color. One of ELDIM major features is the patented optical configuration which allows controlling the angular aperture of the system independently of the measurement spot size.
In EZContrastMS, different automated wheels allow selection of the light beam using 31 band pass filters regularly distributed in the visible range. The system makes automatically a quasi spectral image of the full Fourier plane at each filter wavelength and the sequence is repeated for all the filters. The system is calibrated in an absolute way to reconstruct the spectral radiance of the object at each incidence and azimuth angle.

	- Absolute radiance - High angular resolution - Full viewing angle - up to 88° - Polarization degree - Ellipticity - Color & luminance
