Note
The total displacement reaches from 0 to 200 mm, although the stage translation path is only
100 mm. This results from the mechanical design of the
M2MS M² Meter Set.
Increment: Enter the increment for moving the stage stepwise.
Velocity: This is the speed of the stage when traveling between two positions (e.g., between
the actual and the target position).
Pressing these buttons moves the stage backward / forward for one step, equal to the Incre-
ment .
Pressing this button interrupts the continuous stage travel to a target position.
The slider bar on the bottom of the panel has two functions - it shows the stage position, and
the slider can be moved with the mouse in order to start a stage travel.
M2 Set
The panel "M2 Set" allows to set the lens parameters for the M2MS extension such that the
beam waist before the lens can be calculated. The Lens Type and Focus Offset are chosen by
the user. The software calculates the focal length and beam waist based on the provided infor-
mation, including the wavelength as set above under
Optical Setup .
The focus position is then determined based on internal M2MS parameters, the type of beam
profiler, the focus offset and the determined focal length.
