ReconFlexTM Camera Systems
CMOS Camera Models for Scientific Applications with build-in Single Particle Recognition and Frame Time Correlation in Coordinate Data Streaming. Additional options such as an 16bit ADC (A), an integrated blob recognition algorithm (B) or an integrated super resolution algorithm (S) for fast and time-saving localization microscopy.
With 1920 x 1440 pixels (2.8MP) and frame rates up to 417fps (@8bit) and 234fps (@12bit) the 1920 Series offers the ideal compromise between high resolution and fast imaging. The low readout noise (< 3e-) makes the camera the perfect tool for scientific applications and the setting of an additional hardware RoI allows to reach frame rates of several thousand frames per second.
The 800 series impresses with its very fast frame rate of up to 1577fps (@8bit) and 929fps (@12bit) and a resolution of 800 x 624 pixels (0.5MP). Due to the high dynamic range (80dB) and the low readout noise (< 6e-), the 800 Series is the best choice for fast and low-light experiments and applications such as phosphor screen or YAG crystal screen readout. The setting of an additional hardware RoI allows to reach frame rates of larger 7000fps.
Principle of Blob Finder and Super Resolution Mechanism
The blob finder mechanism enables precise and fast finding of peak coordinates and their counting. It recognises single peak intensities and their coordinates (no. 1, 2a and 3a) directly on the hardware and provides a coordinate list (4a) on the fly. Coordinate lists can be streamed directly assigned to frame time stamps and ADC values. The software assembles virtually noise free images from the coordinates.
The super resolution mechanism increases the resolution of the measurement by determining the peak positions with sub-pixel precision. It upscales the obtained images by a user-defined factor (e.g. upscale factor of 2 for no. 2b and 3b) providing a more precise coordinate list (4b) and a higher resolved coordinate image.
