HartSCI ClearStar Adaptive Optics
Call for price
HartSCI’s ClearStar AO™ system represents a paradigm shift in high-resolution imaging. For the first time, high-performance image sharpening is available as an off-the-shelf product for small to mid-size professional telescopes. ClearStar AO™ overcomes atmospheric blurring to deliver diffraction-limited image quality to science instruments operating in the 750 – 1000 nm wavebands. Built-in hardware and software tools support full and automatic internal calibration. The system connects to the outside world through a simple ethernet port and comes with a full-featured browser-based graphical user interface that can be run on any computer. ClearStarAO™ can also be controlled through an Application Programmers’ Interface (API), enabling fully automatic operation and seamless integration into the observatory environment.
