High Resolution Imaging of Changing Star Brightness
The image shows a study where an ELSEi 2k2k camera from greateyes GmbH was used to observe transients where a star changes brightness.
About ELSEi Cameras
ELSEi integrates cutting-edge, low-noise electronics and ultra-deep cooling technology, while keeping a compact camera design. Multiple readout speeds can be selected supporting pixel rates from 50 kHz up to 5 MHz.
Functionalities include fully flexible binning operation, various trigger and synchronization modes, Crop and Burst mode, software-selectable gain, as well as temperature monitoring of the sensor and the Peltier hot side.
True 18-bit AD conversion enables the exploitation of the full dynamic range of the CCD sensor for the highest performance and SNR. Choose from a wide range of sensors to find the best match with your requirements. ELSEi is ideally suited for detection of very weak signal intensities where a low-noise floor is paramount.
ELSEi cameras are designed for applications in the UV, visible, NIR ranges, including:
- In-vivo fluorescence bioimaging
- Astronomy
- LIBS spectroscopy
- Neutron tomography
- EL / PL imaging
- Ultracold quantum studies
