Optical comparator vertical fixture

Hold your parts virtually in space.

R&R's Optical comparator fixture is the first of its kind. It provides a very effective and efficient way to hold your parts with minimum contact and maximum access.  It can be mounted directly onto the rails of your comparator or the R&R Comparator fixture kit base plate by use of dovetail/jam nuts.*

This Optical comparator vertical fixture will permit your parts to be accurately held in a definite alignment, while the part is extended into the beam of light path for measurement.  The fixture is designed to maximize your view of the part with minimum fixturing component obstructions, unlike traditional bulky and non-repeatable fixturing methods.

*Contact R&R for further information regarding dovetail/jam nuts.
