The FLI Aurora AR571 Mono is a high performance cooled monochrome astronomy camera using the Sony IMX571 CMOS sensor with a resolution of 6244 x 4168 pixels at 3.76μm. The 28.2mm d iagonal field of view is a perfect match for short-medium focal length telescopes. Like all FLI cameras, the AR571 is designed for 24/7 operation, making it ideal for professional remote observatories where reliability is paramount. This latest generation of Sony back-illuminated sensors are natively 16-bit with exceptional sensitivity, full-well capacity, extremely low read noise and linear response to light. With a peak quantum efficiency of 90% and large dynamic range of 93.6dB, the AR571 excels at deep sky imaging of faint targets. The CMOS sensors found in these cameras have a response to light that is linear very close to the saturation point. This means the Aurora series cameras can be used for advanced research and scientific applications like variable star photometry and transiting exoplanets. The regulated thermoelectric air cooler is capable of cooling the CMOS sensor to approximately 50°C below ambient temperature. The sensor temperature is regulated with ±0.1 °C precision. High temperature reduction and precision regulation ensure very low dark current for long exposures and allow proper image calibration. Aurora series cameras are also plumbed for liquid circulation, further increasing cooling capabilities (external liquid circulation connectors sold separately). The USB 3.0 port operates at 5 Gbps while the QSFP fibre optic connections allow for even faster transfer rates and electrical isolation.
