Slide operation
dovetail stage

Miruc Optical Original product with international patent

A significant price reduction was achieved by reducing the number of components and assembly man-hour.
The quality is MADE IN JAPAN !
Thin specification, light weight reduced by 30 % to 40% compared to conventional models and easy sliding operation with combined operation knob and stopper screw make a rapid sliding operation possible, and it allows to slide the desired position and then clamp.
Unlike conventional dovetail stages, since the sliding block is detachable, work or jig can be installed from the back side of the sliding block.
It is ideal for integration into inspection apparatus, etc.

Feature1 High accuracy,30% to 50% price reduction is achieved.

A significant price reduction was achieved by reducing the number of components and assembly man-hour. The quality is MADE IN JAPAN!
Miruc Optical original product with patent and design right. OEM supply and special order is also accepted.

Feature2 Thin, light weight and fast-slide movement operationability is exceptional.

With thin specification wherein the square shape type has a thickness of 15mm, rectangularshape and slim long type has rectangular shape and slim long type has a thickness of 20mm. Weight is reduced by 30 % to 40 % compared to conventional models,with simple and rapid sliding operation.

Feature3 Handle-less and tool-less new concept

Feature4 Sliding block can be installed at both sides,front and back

Unlike conventional dovetail stages, since the sliding block is detachable, work or jig can be installed from the back side of the sliding block.

Feature5 Ideal for integration into inspection apparatus, etc.

Initial positioning fine-adjustment using this stage is conducted in the inspection equipment etc. and it can be almost continuously used as it is in a certain condition after fixing with stopper screw. Usually, only a slight fine adjustment is conducted in actual. This product group is ideal to this application, with easy operation and significant price reduction, it contributes to the improvement and cost reduction of the operation process of equipment industry etc.

MIRUC products
Overseas product×××
The product which poor in precision, you may feel a strangeness in operation of full stroke with sliding the stage from the side by side. The feeling of operation depends on individuals.

■Grind
“Strange feeling, vigorously scratching something when turning the handle.No smoothness.
Many cases occur when lightened harder together between the rack and pinion.”
■Unevenness
For all strokes gets heavier or lighter for unevenness.
Many cases occur when weak tightening between the rack and pinion.
■Gap
Sliding the stage to one side makes the feeling as if the stages are scratched and becomes heavy.
When sliding it on the opposite side makes it feels lighter.
■Backlash
The play between male/female dovetail groove parts.
■Play
The gap between the contact face of gear that is intended to be provided in the direction of movement. By suppressing this gap as much as possible, smooth sliding without backlash.
