High Speed Digital Pathology Slide Scanner

Realtime EF with 3-Camera Structure
Employing the intricately designed 3-camera structure,
Vieworks’ slide scanner VISQUE DPS delivers four different scan modes.

3-Camera Structure

  • Obtains three differently focused images at once
  • Triples the depth of field of the objective lens
  • Produces high resolution images with ZEISS objective lens
  • Scan time and data size comparable to that of a single camera image capture
