Features

Extension Posts and Spacers for Customizable Heights

Threaded extension posts and spacers allow mounting certain optics at non-standard heights. These stainless steel constructed extension posts and spacers provide a wide variety of options for building posts to mount optical components at customizable heights. 

Specially Designed Groove and Peg Extension Post

SR-4P is a special purpose extension post for use with the SR-SC sliding clamp. It features a "V" groove along the axial length of the rod to support the sliding SR-SC clamp and its spring-loaded linear motion. This prevents undesired rotation during alignment, and with Newport’s patented peg fastener, two SR-4P can be aligned as a composite system.
