MECHANICAL DETAIL
Green Camera The camera, through the optical unit, looks up and down simultaneously, this
allows the board image and stencil image to be displayed together on the monitor
screen.
To enable both images to be seen simultaneously, without degradation in picture
quality, a high resolution camera is used. The camera has a resolution of 752 x
582 pixels
Optical and Lighting
Unit
The optical and lighting unit performs three main functions:
• Redirection of the board and screen images onto the camera sensor
• Illumination of the board and screen for image capture
• Focusing of the board and screen images

The board and screen images pass through their respective beam splitter cube to
the prism, which deflects the images by 90° towards the camera. The images
pass through a lens block which deflect the beams through the telecentric stop
to the camera. The distance between the lens block and the telecentric stop is
fixed. By moving the lens block and telecentric stop in relation to the optical
unit enables focusing to take place.
The optical unit employs LEDs for direct and oblique lighting. The direct
lighting is achieved by a block of six LEDs, one block for board lighting and one
for screen lighting. The oblique lighting is achieved by a ring of twelve LEDs
around the glass window, one ring for board lighting and one for screen lighting.
Figure 17-3 LED Ring Lighting
Each lighting group can be set by the operator to a level between 0 and 15, where
15 is the brightest.
The set levels for the lighting are stored in the product file, allowing a lighting
setup to be transferred from one machine to another simply by loading a new
product file.
Green Camera 2 The camera, through the optical unit, looks up and down simultaneously, this
allows the board image and stencil image to be displayed together on the monitor
screen.
