Imaging Extensions

Fast and Flexible Imaging Platforms

  • “Complete version” for imaging in transmission and reflection
  • “Flexible version” for horizontal, vertical and oblique positioning
  • “Fast version” for TeraFlash smart, unique speed of 1600 pixels per second
  • Data filtering in both time-domain and frequency-domain possible

TOPTICA offers Imaging Extensions for both TeraFlash pro and TeraFlash smart. The Complete Imaging Extension scans a sample through the focus of the terahertz beam. Users can quickly reconfigure the optics from a transmission setup to a reflection geometry and vice versa. The Flexible Imaging Extension includes a compact reflection head that moves on an aluminum frame. This assembly can be positioned horizontally, vertically or at any oblique angle and is well suited to study heavy objects, paintings or murals. Finally, the Fast Imaging Extension is compatible with the TeraFlash smart and enables imaging at 1600 pixels per second, an industry record for commercial time-domain terahertz systems.
