Paper Compares CMOS, CCD and EM-CCD Camera Technologies
In a recently published paper “Effect of UV Scattering on Detection Limit of SO2 Cameras,” researchers compared CMOS, CCD, and EM-CCD camera technology to investigate which is providing the best sensitivity and accuracy and ultimately the best detection limit for remote sensing applications, such as DOAS or FTIR.
An outfield experiment was conducted on a ship exhaust, and the results were compared with theoretical models. The study proved that the detection limit of the SO2 UV camera deteriorates with the decreasing atmospheric visibility, the lengthening detection distance, and the increasing aerosol content within the exhaust plume. In addition, the sensor technology of the camera systems also played a key role in the detection limit.
The ELSE camera from greateyes, featuring an optimized 2k2 CCD sensor as well as deep sensor cooling and 18bit digitization, performed very well in these experiments.
ELSE Cameras for UV VIS NIR
Based on a unique platform concept, greateyes offers a portfolio of ELSE scientific cameras for imaging and spectroscopy in the UV, VIS and NIR range (wavelength range of 160–1100 nm). The deep-cooled, high-performance CCD detectors are very compact. They combine highly sensitive sensors with ultra-low noise 18-bit electronics for optimal detection of weak signals. Select among different pixel formats, several sensor technologies and various sensor coatings to find the best solution for your imaging or spectroscopic application.
The full-frame CCD sensors are integrated in hermetically sealed vacuum chambers with multi-stage Peltier elements. The cameras provide a rich set of functionalities including flexible binning operation, various trigger and synchronization modes, software switchable gain as well as temperature monitoring of the sensor and the Peltier hot side.
