Motorized Aperture Module

The X-Y Theta Aperture Module is a motorized device designed to control laser beam size and shape for applications requiring precise patterning.

Many applications demand a specific size and shape of the working laser beam. Our mo­torized slit apertures can provide a square beam that controls the X-axis, Y-axis, & Theta rotation. Standard X and Y ranges are from 0 to 2.5 mm with 90 degree theta rotation; however, larger slit sizes can be accommodated. All movements of our slit are completed in less than 1 second, providing slit solutions at production speeds.

Please contact us to receive a quick quote or to outline your application if our commercial products do not exactly fit your needs. We can discuss customized solutions for you.
