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) 

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.
