QSI 540 Cooled CCD Camera

The QSI 540 Cooled CCD Camera from Quantum Scientific Imaging, Inc 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 large 2048x2048 sensor in the QSI 540, provides unprecedented field of view in a camera using standard 1¼" filters. The compact design and internal color filter wheel of the 540wsi allows unvignetted, filtered images even with very fast optical systems.

Because the internal color filter wheel is positioned very close to the focal plane in QSI 500 Series cameras, the 21.4mm diagonal Kodak KAI-04022 sensor experiences no optical vignetting through standard 1¼" filters, even with fast optical systems.

The compact design of the QSI 500 Series allows the 540 to set a new benchmark for cost and size in a high performance, full-featured scientific CCD camera. With optional features and upgradeability, the 540 can be tailored to fit your needs today and in the future.

The 540 camera system is supported by industry leading image acquisition software and development tools are available for creating custom Windows or Linux imaging applications.

The 540wsg is now available with an integral Off-Axis Guider allowing you to guide using the light from your main telescope while picking off the light from the guide star in front of the filters.

Seven different models are available employing a comprehensive range of monochrome and single-shot color scientific grade CCDs. A variety of options and accessories are available to meet your astronomical requirements.
