Collimation Tester

The Newport Collimation Tester 20QS20 makes use of a technique called “Shearing Interferometry.” This is a null method used to test the collimation of laser light whose coherence length …

Technical Notes

Focusing and Collimating

As a first example, we look at a common application, the focusing of a laser beam to a small spot. The situation is shown in Figure 5. Here we have a laser beam, with radius y1 and …
