WebUnfortunately several things mitigate against this. Binocular heads get knocked, manufacturers don’t provide any external alignment adjustment (apart from width), and human eyes are different; not just in focus terms, but in alignment. These two defects both tend to get worse with age, focus is relatively easy to correct, alignment isn’t. WebFigure 1 shows the schematics of the x-ray instrument. An alignment undulator is located 20 m or more upstream ofthe accelerator beam line to be positioned with a retract-able x-ray pinhole (source pinhole) located midway be-tween the two.

"WebPrisms that deviate the ray path, rotate the image, or simply displace the image from its original axis are helpful in many imaging systems. Ray deviations are usually done at angles of 45°, 60°, 90°, and 180°. This helps to condense system size or adjust the ray path without affecting the rest of the system setup.
