The RLM356 optical delay stage is the perfect application for spectroscopy that requires high repeatability and ultra-precise delays.  With 356mm of travel, the RLM356 is a compact stage that is made with high quality components including, direct drive linear motors and ultra-precision linear guide rails to ensure the precision necessary for a delay stage.  The RLM356 has excellent pitch and yaw coupled with its linear accuracy and repeatability makes it a leading choice for a drop in or designed to application delay stage.
