The Chameleon USB3 uses Sony's Pregius global shutter CMOS technology, offering crisp, clear, distortion-free images at high speeds. These sensors outperform traditional global shutter CMOS sensors and have become a viable alternative to CCD sensors. The IMX265 sensor features a smaller and very popular pixel size of 3.45 µm. The smaller pixel size is balanced with lower Temporal Dark Noise thereby maintaining the Pregius' lines outstanding imaging performance.
The 3.45µm pixel size is very well suited for Planetary imaging. Its small pixel size which is effectively doubled for colour chipsets due to the bayer mask, gives it ideal sampling when used with larger aperture, long focal length instruments.
Astrograph are the Point Grey specialists. We supply all USB 3 Colour cameras with a 2m USB3 cable and a CD containing all the software you need.
