Description

The QSI 540 model 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 540 ideally suited to a broad range of demanding astronomical, scientific, medical and industrial imaging applications.

  • 4.2mp 2048x2048 KAI-04022 sensor
  • Low noise, wide dynamic range
  • Very fast electronic shutter
  • Up to 45°C CCD cooling


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 QSI 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 QSI 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.

 

4.2mp 540wsi allows LRGB imaging through standard 1¼" filters resulting in a breakthrough in size, weight and cost.

  • 4.2mp 2048x2048 KAI-04022 sensor
  • Low noise, wide dynamic range
  • Very fast electronic shutter
  • Up to 45°C CCD cooling
  • With mechanical shutter
