Calibration Optical Axis
To calibrate.
The optical axis calibration is performed by a Johansson gauges blocks. The objective is to make the optical axis as parallel as possible with the Z axis of movement.
a)Automatic procedure:
Find, by actuating the motor along the Z axis, the two positions at the two ends of the depth of field in which the gauge block is in focus and note the values.
Start the calibration procedure from the Settings Menu, select the Z axis motor from the Motors drop-down box.
Drag and change the size of the rectangle on top left to include the gauge block and enter its dimensions in the box on the right.
Always in the box on the right, enter the two previously noted positions of the motor.
Press once on the image outside the rectangle containing the gauge block.
At the end of the two measurements the value of the error in pixels and the offset angle in degrees will be shown. The image will indicate how to move the plan to correct the error.
b)Manual procedure:
First find, by manually operating the Z axis, the two positions at the two ends of the depth of field in which the gauge block is in focus and note the values.
Start the calibration procedure from the Settings Menu, select None from the Motors drop-down box.
Drag and change the size of the rectangle on top left to include the gauge block and enter its dimensions in the box on the right.
Using the motor console, position yourself manually on the first position, click on the image outside the selection rectangle to get the first pair of values.
Position yourself manually on the second position, click on the image outside the selection rectangle to obtain the second pair of values.
In the right box Pt(point) near optic select which of the two points is closest to the optics.
Press Evaluate at the end of the two measurements and the value of the error in pixels and the offset angle in degrees will be shown. The image will indicate how to move the plan to correct the error.
After adjusting the plan, press the basket icon and repeat the procedure until the error is minimized.
With the Live button the algorithm continues to calculate the second position, useful to see what happens adjusting the plan, but not accurate as repeating the entire procedure.
