PRELIMINARY

4.5 Positioning Accuracy of the Sensor Chip in the Camera

Position accuracy of the sensor chip in the horizontal and vertical direction is + 2 mils. Rotational positioning accuracy is as shown. Reference position is the center-line of the four M4 mounting holes 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.

4.6 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.

4.7 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.

•Fairchild Imaging cameras work well with either tungsten or solid-state (LED) illumination sources. With tungsten sources, spectral shaping using a typical BG38 filter is recommended.
