Product Family Description

X-Y Adjustable
Pre-Mounted on a Gimbal Tilt-Table
Open-Style Design

Our precision open-style spatial filter mechanism features a ball bearing, spring-loaded dual stainless rail objective movement with a micrometer drive. The pinhole mount accepts standard ⅜" (9.5mm) discs from our line of Pinholes & Slits and is X-Y adjustable via two fine thumbscrews. This entire assembly is mounted on a gimbal tilt-table with X-Y two-axis adjustment by two fine thumbscrews. A ¼-20 tap hole on the gimbal platform base allows for easy mounting to posts or other positioning equipment. The Understanding Spatial Filters application note will help you select the appropriate components for your laser application.

Note: Spatial Filter does not operate with 5.5mm objective.
