Description
The Aries 1517 is a new‑generation large BSI sCMOS astronomical camera developed by Tucsen using vacuum cooling technology. Compared with conventional CCD cameras, it offers a more compact, lightweight design and lower power consumption to meet key astronomical imaging requirements, including wide field of view, high dynamic range, and long‑exposure, while greatly simplifying system integration.
Vacuum Cooling System
Engineered for Extreme Astronomical Environments
– 5+ years vacuum stability, reducing maintenance and cost
– 0.023 e⁻/pixel/s @ -40°C, 4.3× lower dark current
– Custom cooling depth, adaptable to different observation needs
Back-Illuminated sCMOS
Optimized for Large-Format Low-Light Imaging
– 87 mm format / 15 μm pixels, improved accuracy with less stitching
– 95% QE & 1.2 e⁻ noise, high sensitivity with less stacking
– Electronic rolling shutter, stable and precise timing
– 16-bit / 95 dB dynamic range, suited for complex star fields
System-Level Architecture
Built for Reliable Deployment
– COF + CameraLink, stable transmission with redundancy
– GPS timing, accurate tracking and synchronization
– <100 W power, suitable for resource-limited environments
