Description
QHY 5-III-585C Planetary and Guiding Camera is one the first new 2nd generation of QHY5III Series planetary cameras and guiders. The QHY5III585C is an enhanced version of its predecessor, the QHY5III485C. It has a high sensitivity in the near infrared similar to that of QHY5III462C, while the dynamic range performance has been greatly improved. It has a large 1/1.2-inch sensor and excellent noise performance with zero amplifier glow. The QHY5III585C comes with a UV/IR filter and an IR850nm filter.
Extended Near Infrared Sensitivity
In this latest generation of sensors, the photodiode portion of the pixel well is physically deeper than in previous sensors, allowing photons of longer wavelengths to penetrate deeper into the substrate. This dramatically increases the sensor’s sensitivity to red and near-infrared (NIR) light. The sensor displays almost equal peak sensitivity to NIR light as it does to light in the visible spectrum.
Enhanced Dynamic Range
The IMX585 is a Sony Starvis II sensor that exhibits not only high sensitivity but also high dynamic range (HDR) of 88 dB, approximately eight times that of the previous generation IMX485 image sensor in a single exposure. It has improve sensitivity in the near-infrared range, approximately 1.7 times that of the IMX485C.
