AVT Guppy Series
Method of Positioning: Automated mechanical alignment of sensor into camera front module.
(lens mount front flange)
Reference points: Sensor: Center of pixel area (photo sensitive cells).
Camera: Center of camera front flange (outer case edges).
Accuracy: x/y: +/- 0.25mm (Sensor shift)
z: +50 / -100μm (for SN > 84254727, optical back focal length)
+0 / -100μm (for SN > 252138124, optical back focal length)
D: +/- 1° (Sensor rotation)
AVT Marlin, Oscar, Dolphin, Pike, Stingray
Method of Positioning: Optical alignment of photo sensitive sensor area into camera front module.
(lens mount front flange)
Reference points: Sensor: Center of pixel area (photo sensitive cells).
Camera: Center of camera front flange (outer case edges).
Accuracy: x/y: +/- 0.1mm (Sensor shift)
z: +0 / -50μm (Optical back focal length)
D: +/- 0.5° (Sensor rotation)
Note: x/y - tolerances between c-Mount hole and pixel area may be higher.
