CIAO SWIR
Improve your optical link capability with adaptive optics
CIAO SWIR is a compact adaptive optics system for Satellite Communication, Free Space Optics and Quantum Key Distribution. By removing static aberrations due to mirror misalignment, thermal or gravity effects and by drastically reducing the effect of air turbulence, CIAO improves the coupling efficiency in a single-mode fiber and therefore improves the optical link data-rate and stability.
Adaptive optics solution CIAO SWIR enables reliable, secure and fast communication
Connecting directly to the telescope, CIAO SWIR is inserted between the telescope’s focal plane and the user fiber holder without modifying the optical path. Setup is facilitated by the embedded tip-tilt alignment interface and autocalibration tools. The user can close the adaptive optics loop with a simple click, to activate the aberration correction and to reach a stable data-rate.
Key Features+ Easy to install add-on for ground-based telescopes from 200 mm up to 1m diameter
+ Corrects up to 40 modes thanks to a piezo-electric deformable mirror + Fast SWIR Shack-Hartmann wavefront sensor, operating at more than 4.5 kHz + Internal source allows a very easy and simple auto-calibration + User access to the beamsplitter (spectrally neutral or dichroic) + Single-mode fiber holder included + Compatible with up to 100 µW (-10 dBm) of 1550 nm at the input
|
Best For+ Downlink satellite communication (SATCOM) |
Software
+ Dedicated software for fast AO loop control
+ Many parameters are available to optimize the loop and adapt the configuration to the telescope, the seeing conditions, the target and the application.
WAVESKY Adaptive optics Software
+ WAVESKY was made with a RunTime approach, meaning it has no GUI. Launch the server, connect your client through TCP-IP and drive the loop and run diagnostics.
+ It includes C++ and Python client examples
