4.5 Lenses
Fairchild Imaging does not supply lenses.
4.6 Positioning Accuracy of the Sensor Chip in the Camera
Positioning accuracy of the sensor chip in the horizontal and vertical direction is + 0.2 mm.
Rotational positioning accuracy is as shown. Reference position is the center of the camera
housing.
Rotational positioning accuracy is as shown. Reference position is the center of the camera
housing.
Since the translatory and rotational positioning tolerance depend on each other, the worse case of
maximum rotational and horizontal/vertical mis-positioning can not occur at the same time.

4.7 Illumination
In your application you must know the amount and wavelengths of light required. Some additional
things you want to consider respective to illumination are the characteristics of your light source
and the spectral characteristics and speed of the object(s) being inspected.

4.8 Light Sources
When selecting and setting up your light source you should be aware of the following.
• Light sources do age over time.
• When light sources age, they may produce less/more light in some areas of the spectrum.
