Z-Fine Adjustment M

This is the most precise Z-fine adjustment of our Microbench elements with a direct mount for 25 mm outer diameter components. The Z-Fine Adjustment is equipped with a fine-adjustment screw with 0.25 mm pitch. The translation range is 1.5 mm with an accurracy of 1 μm. Because of the 1-32UN internal thread this unit fits to our Tube Mounting System C. This component is ideally suitable for example for fiber alignments due to its exact centering without nearly no tilt.

The Z-Fine Adjustment is available in two versions, with micrometer or with fine adjustment screw. The micrometer screw has a pitch of 0.25 mm. The spindle has a hexagon socket and can be driven by the provided knurled hexagon knob. If the hexagon socket is not needed, the knob can be glued in.
