| UMaster Series |
Today facing Non-uniformity is a major problem
to manufacturers and OEM...
Imaging colorimeters are all based on CCD sensors and generally color filters. The difference between the systems lays in the accuracy, the signal over noise ratio, the spatial resolution and the quality of the imaging optics.
UMaster is based on a Peltier cooled CCD sensor with true 16-bit analog digital converter. Four color filters dedicated to each CCD sensor are mounted on a motorized color wheel. A second motorized wheel with flat densities is also available for an automatic adjustment to the source luminance.
- High Accuracy
ELDIM is manufacturing on its own all the key components of its systems. The quality of the optics is optimum thanks to advanced technologies such as magneto-rheological polishing or stitching interferometry. Antireflective coatings and optical alignments are also performed in house to reduce straight light and parasitic polarization. UMaster uses an objective telecentric on the sensor side for imaging. The color accuracy is ensured using 4 dedicated color filters adapted to the spectral response of each CDD. UMaster uses a new technology based on electron beam evaporation that gives filters with higher transmittance and enhanced accuracy.
- High Sensibility
Peltier cooled CCD sensor with true 16-bit analog digital converter and color filters with high transmittance allow optimum sensitivity for UMaster. Large size CCD versions can be used to detect very low light levels while maintaining a good spatial resolution.
- High Dynamic
UMaster integrates different neutral density filters on an automated wheel. These neutral densities are spectrally flat thanks to the use of interference coatings deposited on neutral glass. Automated control of these densities is available for each color filter independently to improve the accuracy in particular for LED type sources.
- A range of imaging objectives
UMaster is available with objectives of different aperture (8° and 16°) and different CCD sensor resolutions (1M to 16M pixels). Additional optics for high spatial resolution are also available.
- More than just Luminance & color: Polarization
In addition to luminance and color imaging, UMaster can realize polarization imaging at different wavelengths. This option is available for all the wavelengths in the visible range (band pass 10nm). The system performs automatically seven measurements with different polarizers and wave plates from which it computes all the polarization parameters throughout the image in addition to radiance. Stokes vectors are available for each pixel of the image.

| EZContrast Series |
High Performance Fourier Optics Viewing Angle Instrument
ELDIM has been manufacturing viewing angle instruments based on Fourier optics for more than 15 years. One of their key features is the patented optical configuration which allows controlling the angular aperture of the system independently of the measurement spot size.
Extreme grazing angles (88°) are measured with an excellent accuracy thanks to a very high light collection efficiency .
- High speed
The full viewing cone is measured with high incidence and azimuth angular resolution within seconds for luminance and chromaticity and minutes for radiance.
- High accuracy
Every ELDIM system follows a strict manufacturing and calibration procedures. Spectral response of each CCD sensor is measured and each filter -designed on purpose- is controlled by spectro-photometry.
-
High efficiency
ELDIM uses a patented optical configuration that allows optimum light collection even at very high angles. This cosine compensation matches the behavior of a spectro-photometer on a goniometric stage.
- High reliability
ELDIM is manufacturing on its own all the key components of its systems. The quality of the optics is optimum thanks to advanced technologies such as magneto-rheological polishing or stitching interferometry. Antireflective coatings and optical alignments are also performed in house to reduce straight light and parasitic polarization.
