The standard QSI 532 camera employs a 3.2 megapixel Kodak Enhanced Response full-frame CCD image sensor with microlens technology. The high quantum efficiency, wide dynamic range and low noise performance make the 532 ideally suited to a broad range of demanding astronomical, scientific and industrial imaging applications.
The KAF-3200ME sensor has a photoactive array of 2184W x 1472H 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 77db. The sensor employs a true two-phase charge transfer technology with a transparent gate that significantly increases optical response compared to traditional front illuminated full frame sensors. Micro lenses cover the surface of the CCD and focus the light through the transparent gate to further increase optical response.
Mechanical Shutter
The Model 532s incorporates the internal mechanical shutter in the 'mid-size' camera body configuration . The shutter is not only used for timing exposures, but can be left closed to produce 'dark frames' for subsequent image processing. Exposures can range from 0.03 seconds to 240 minutes.
Internal Color Filter Wheel
The Model 532ws adds an internal five position filter wheel to the camera in a 'full-size' camera body. The filter wheel accepts any standard 1.25" filter and can be purchased with various filter configurations. The filter wheel can easily be removed and replaced to change or clean the glass filters. Additional filter wheels can be purchased allowing quick interchange of different filter set configurations.
532wsg adds Integral Off-Axis Guider
The Model 532wsg camera has the internal mechanical shutter and color filter wheel like the 532ws, plus it adds an integral Precision Off-Axis Guider (OAG). This
allows guiding using the light from your main telescope while picking
off the light from the guide star in front of the filters. Upgrade to 532wsg>>
