Product Description

Pure rotational motion about a virtual pivot point
1° graduation markings on the edge
Anti-backlash spring-loaded design with interchangeable actuators
Full stage locking via side-mounted set screws
When used with a 20 mm travel vernier micrometer: GON65-L-M offers ±5° rotational motion; GON65-U-M offers ±10° rotational motion

The GON65 series goniometric stages are designed for precise rotation of objects within a small angular range, rotating about a fixed pivot point in space. These goniometers feature precision dovetail slides driven by actuators and spring loading to minimize backlash, a common issue in worm gear-driven stages. The spring-loaded design also enables actuator interchangeability, allowing users to select adjustment sensitivity from a variety of actuators such as precision adjustment screws, differential micrometers or motorized actuators.

Technical Notes

Our goniometric stages enable unobstructed pure rotational motion about the pivot point within the rotational angle range. The compact, stackable design allows one stage to be mounted on the top surface of another, with the pivot points of the two stages overlapping.

The precision dovetail design, combined with anti-backlash lead screws and micrometers, enhances the angular positioning capability of the top plate for accurate and repeatable positioning. The stage can be locked using side-mounted set screws to fix all motion of the stage.When paired with a 20 mm travel vernier micrometer, the upper carriage of the GON65-U-M provides ±10° rotational motion, while that of the GON65-L-M provides ±5° rotational motion.

A hex screw on the side of the stage securely locks all motion of the stage in place (tightened with a 2 mm hex key).

The stage surface features an array of threaded mounting holes, including 7×M6 and 4×M3 threaded holes, for easy attachment of optomechanical components. The series can be configured in a stacked arrangement via M6 countersunk mounting holes or mounted onto mini-series optical breadboards.

Note: Removal of the base plate from the goniometric stage is not recommended, as this may compromise the precise adjustment of the stage and require recalibration or readjustment.
