The KS1D features locking adjusters in combination with an ultra stable mechanical package to provide long-term stability. The angular adjustment range is ±4° when the spacing between the front and back plate of the mirror mount is 0.120".

Two of the mount's three adjusters incorporate our differential drive mechanism (click Complete Product Details above for more information). This high resolution drive system (Patent Pending) has both coarse (318 µm/rev) and fine (25 µm/rev) adjustment capability. The fine adjustment drive system uses two lead screws; one pushes the center spindle forward at 400 µm per revolution and one pulls it back at 375 µm per revolution. The resulting total forward motion of the center spindle is just 25 µm per revolution, equating to 660 µrad per revolution. The differential drive mechanism is actuated by inserting a hex wrench through the coarse adjuster knob and turning the intermediate actuator embedded in the adjuster screw.
