Uniformity
UMASTER
UMaster imaging equipment allows to measure luminance, color and polarization.
UMaster is definitely the most sensitive solution of the market with high transmission filters with six color filters mounted on a motorized color wheel and high quality optics
What purpose
Overview
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.
ELDIM is manufacturing on its own all the key components of its systems.
The quality of the optics is optimum thanks to advanced technologies
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).
Features
- Imaging Luminance, Color and Polarization
- Cooled sensor
- MURA defect detection
- Spatial resolution down to 9µm with additional option
Applications
- For QC
- R&D with a large range of optics
- Mass production
