…for direct measurements--the beam can be focused at a distance for the smallest spot size to optimize the system resolution. The front knob allows for easy adjustment. During adjustment the optics do not rotate and focusing action is even and uniform while beam alignment is maintained1 . A locking…

…limitations on the smallest via diameter it can reach. One limit is caused by light diffraction. Specifically, the smallest focused spot size to which a laser beam can be focused is directly related to its wavelength. Longer (e.g., far infrared) wavelengths, cannot be focused as finely as visible…
