Optical cell assemblies accept optics from 25mm (1 inch) to 4.25 inches in diameter, and consist of a cell, removable thermal spacer, and a threaded retainer ring. Each cell has a ΒΌ-20 tapped hole that accepts our stainless steel posts for stand-alone use in breadboard configurations. Each cell also has a male thread that fits our Optical Cell Kinematic Mounts for more controlled alignment. Construction is black anodized aluminum.
