CIAO VIS
Improve your telescope resolution with adaptive optics
CIAO is the go-to telescope adaptive optics solution for Astronomy. By removing static aberrations due to mirror misalignment, thermal or gravity effects and by drastically
reducing the effect of air turbulence, CIAO improves the resolution of images or increases the coupling efficiency in a single-mode fiber.

CIAO VIS adaptive optics solution enables high-resolution imaging for Astronomy
Connecting directly to the telescope eyepiece, CIAO is inserted between the telescope’s focal plane and the user plane (sensor or fiber holder) without modifying the optical path. Setup is facilitated by the embedded tip-tilt alignment interface and autocalibration tools. After pointing on the target, the user can close the adaptive optics loop with a simple click, to activate the aberration correction or to lock in very fine pointing.
Key Features+ Easy to install add-on for ground-based telescopes from f/8 to f/22, 200 mm up to 1 m diameter
+ Fast low light Shack-Hartmann wavefront sensor, 1 kHz Operating between 400 nm to 1100 nm + Internal source allows a very easy and simple auto-calibration + Adjustable tip-tilt off-axis ball point for optical alignment + Optional Single-mode fiber holder for white light interferometry, spectroscopy |
Best For+ High-resolution imaging on planets or solar surface thanks to its compatibility with extended source |
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.
