Long Exposure CMOS Cameras

The Retiga E family series of CMOS imaging cameras composed of the E7, E9, & E20, introduces extended exposure imaging to the CMOS technology landscape. Pushing boundaries in thermal noise control, these cameras have an ultra-low dark current of <0.001 electrons per pixel per second enabling photographic captures capable of up to an hour. Expanding exposure times creates detection in even the weakest signals, works best in imaging luminescence.

Extended Dynamic Range

One of the main features found in all three of Retiga cameras is the Extended Dynamic Range (EDR) mode. By leveraging the benefit of a large full well capacity and a reduced read noise, the system achieves an enhanced dynamic range, approximately 2.5x greater than standard modes, successfully recording both bright and dim signals concurrently in the same capture.

Small Pixel Imaging

The Retiga E20 is equipped with the smallest pixel size to date, measuring $2.4\ \mu\text{m}$ which facilitates high-resolution imaging even when using low magnifications. Utilizing a vast 20-Megapixel array ( $5472 \times 3648$ ), the E20 is capable of resolving tiny details across large samples, in a enabling high-throughput way. By offering minimal noise contribution alongside an elevated peak QE (Quantum Efficiency), the camera guarantees the production of high-quality images, even under challenging low-light conditions.

High Speed Mode

In addition to its “Long Exposure” mode, which supports exposures long exceeding 20 minutes due to its ultra-low dark current, the Retiga cameras offer a “Fast Capture” mode, enabling speeds of over 50 frames per second.

OEM Integration

The Retiga E7 is designed for seamless integration. Its compact size and single-cable interface ensure straightforward hardware setup. With features like onboard triggering, compatibility with Windows and Linux, and support from our dedicated OEM team, integrating and customizing the Retiga CMOS cameras is effortless.
