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.

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.
