|Micrometer||Kohzu standard micrometers offer precise ground-screw positioning and 10 micron resolution measured on laser etched vernier-scale along actuator body.|
|Fine Pitch Positioner||Kohzu's Fine Pitch Positioner (FPP) was developed for precise positioning. It has both coarse and fine position adjustments, a minimum resolution of 0.5 microns and an unrivaled 0.05 micron sensitivity.|
|Handle-Wheel||Kohzu handle-wheel actuators with 25 divisions per revolution or no scale are also available. Device resolution is calculated by dividing lead-screw pitch by the number of divisions on the actuator barrel.|

|Caliper-Lock||The caliper-lock is used on most linear travel stages. In this mechanism locking is achieved by clamping two flat metal calipers against both sides of a flexible stainless plate (in similar fashion as calipers on a disc brake) by tightening a knurled thumb-screw. The benefit of this mechanism is positive locking with minimal lateral position displacement.|
|Spring-Plate Lock||Kohzu's spring-plate locking mechanism is used on all swivel-arc stages. It uses a flexible plate that deflects when locking screw is tightened.|
|Rotary Stage Table-Lock & Travel-Stop||Kohzu manual rotary stages are fitted with two separate locking mechanisms. First is a table-lock used to lock coarse rotation. The second lock is an actuator travel-stop and is used to prevent fine rotation produced by stage actuator. The travel-stop restricts forward (CW) actuator travel. However, it does not impede reverse (CCW) actuator travel. Stages fitted with FPP differential actuators do not include a travel-stop, because it can damage the FPP actuator if improperly used.|
|Actuator-Lock||Actuator-Lock is used to vertical linear stage. Preserve the handle rotation.|
Stage lubricants can be changed for clean-room and vacuum applications with strict lubrication requirements with charge.

|Ultra-High Vacuum||10-5Pa～10-8 Pa||10-7 Torr～10-10 Torr|
|Extreme-High Vacuum||≦10-8 Pa||＜10-10 Torr|
|Mounting Kohzu stages is quick and simple. Mounting holes are provided on stage base and are counter-bored for standard metric socket-head screws. To access mounting holes (two at a time) move stage to each end of travel. Kohzu also offers a selection of adapter plates to facilitate stage mounting to third-party devices with custom bolt patterns. .
* You should take care to move back the stage from end of travel, there is heavy damage caused by spring kickback.
|The length of counterbore's shaft for mounting is described "Shaft Length ** mm"(Top figure, left) in catalog drawing.If counterbore does not exist on mounting part, depth size of base will be shaft length size (Top figure, right).|
