A raster scan takes hours to build a single image. The RIGI microbolometer camera takes it in a second.

Not every experiment fits inside a laboratory. The titanium-strong PCA Scanner fits in an Ikea bag and it won’t break. Attach it to a drone. Throw it in your car. Carry it inside caves or forests.

Laser — The system engine is a standard Toptica laser for THz systems, with fiber compensation and soft mode-locking for optimum THz performance. It is extremely reliable, with a zero failure rate across all of our systems for years now.

Emitter & Detector — Fraunhofer HHI antennas, commercialized exclusively by Toptica Photonics & Menlo Systems DE. Type 1: standard, with specifications. Type 2: high power, a new model, with power up to 300 uW.

  • ▸ Spectroscopy using the PCA as a detector: super fast, > 60 dB in < 10 sec.
  • ▸ Real-time imaging using the RIGI camera as a detector.
