The QSI 6120 model camera employs an 12mp Sony CCD image sensor. This new generation of Sony sensor offers remarkable sensitivity with peak QE of over 75%. The high senstivity, wide dynamic range, dual read rates, low noise performance and internal 5 or 8-position color filter wheels make the QSI 6120 ideally suited to a broad range of demanding scientific, medical, astronomical, and industrial imaging applications.
The QSI 6120wsg is available with an Integrated Guider Port (IGP) allowing astronomers to guide using the light from the main telescope while picking off the light from the guide star in front of the filters.
The 6120 camera system is supported by industry leading astronomy and microscopy image acquisition software plus a full camera control API is available for creating custom Windows or Linux applications.
