Atik New QSI 726 CMOS Camera
In two decades, much has changed beyond recognition. Sensors are now back-illuminated CMOS with native 16-bit digitisation. QE is an amazing 90% and readout is a speedy 120 million pixels per second over USB3, a performance that once was unimaginable. What is maintained by QSI’s newest cameras is the integrated design, attention to detail, and bulletproof reliability.
In the design of the 700 series we have taken our best technology. Filterwheels are mechanically indexed to ensure the most precise locations and perfect flat fields. The fused silica window is dew resistant and is coated on both sides with high transmission anti-reflective coating to minimise halos. The cameras use a highly efficient 2-stage Peltier cooler that draws less current and delivers more cooling than some other cameras.
About QSI :
QSI cameras are designed in Norwich, UK by a dedicated team having many years of experience in astronomy. Skills include 10-layer high-speed PCB
design and platform-independent software code base. The manufacture takes place in a state-of-the-art facility in Lisbon, PT.
