Surveyor Software with Turboscan for Real-Time Mosaic Imaging

Microscope lensesObjective Imaging’s Surveyor automated scanning and imaging with Turboscan enables scanning and near perfect-image mosaic creation at camera frame rates.

Scan the entire slide in seconds, and then effortlessly relocate to areas of interest with a simple click. Quickly get the specimen overview to aid in understanding the relationships between microscopic features and overall structure. Save your work for later review, discussion, and publication.

Based on the OASIS-blue controller with the BLUE-EXPIO Encoder and Trigger interface module or OASIS-AF analogue video processor option, Surveyor with Turboscan provides everything a microscopist needs for surveying, relocating, printing and saving at a new standard in high-performance automation.

Turboscan Highlights:

  • Scanning and acquisition at camera frame rates
  • Support for various digital and analogue cameras
  • Real-time high-quality image tiling
  • Real-time shading correction
  • Fast and accurate relocation
  • Freely mix scans at various magnifications and locations
