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.
