Overview

UMaster is based on a Peltier cooled CCD sensor with true 16-bit analogue-digital converter. Four colour filters dedicated to each CCD sensor are mounted on a motorized colour 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 colour imaging, UMaster can realize polarization imaging at different wavelengths. This option is available for all the wavelengths in the visible range (bandpass 10nm).

FEATURES

  • Imaging Luminance, Color and Polarization
  • Cooled sensor
  • MURA defect detection
  • Spatial resolution down to 9µm with an additional option
