Magnification of Unstable ResonatorsFor the analysis of an unstable resonator, its round-trip magnification M is an important parameter. Essentially, it tells how much the transverse position of a beam on a resonator mirror increases within one resonator round trip. For certain common unstable ...
A second flat mirror in the optical path is dichroic to pass visible light from the illuminated sample to the CCD camera. The on-screen captured image magnification is about 50×. The LTB laser control firmware allows attenuation of the output energy in a step-wise manner with 250 steps in...
Barrel distortion is the kind of aberration that compresses the edge of the image plane and thus it can make the lateral magnification decrease with the increase in the field of view. The barrel distortion could then be employed to improve the illumination of the edge field of view. However,...
