Focused spot sizes are always larger when M
2
> 1. This image depicts the focused spot sizes for larger input
beam sizes also with M
2
= 1. Observe that a 10mm beam is near the resolution limit of the camera.
The next image shows these same large beams sizes with an M
2
= 2. Now none of the focused spot sizes of
these examples are near the resolving limits of the camera.
The next set of images demonstrates the effect of the focused spot size for variations in wavelength. Notice
that shorter wavelengths focus smaller than longer wavelengths.
