Quantum Scientific Imaging Qsi 540i Monochrome Cooled Interline CCD Camera with 4.2MP KAI-04022 Image Sensor with Microlens Technology, Electronic Shutter

The QSI 540i camera employs a 4.2mp Kodak interline transfer CCD image sensor with microlens technology. The increased Field of View, high quantum efficiency, wide dynamic range and low noise performance make the 540i ideally suited to a broad range of demanding astronomical, scientific, medical and industrial imaging applications. The KAI-04022M sensor has a photoactive array of 2048W x 2048H pixels. It has excellent quantum efficiency between 350nm and 1000nm with significant enhancement at the blue end of the spectrum. Low dark current and high pixel charge capacity result in a dynamic range exceeding 74db. The sensor employs a vertical overflow drain that provides both antiblooming protection and a fast electronic shutter. Micro lenses cover the surface of the CCD to focus the light into each pixel to increase optical response.
