The Newport 845HP-01 Digital Shutter Controller delivers precision timing and control for optical shutters in scientific and industrial research environments. This compact controller synchronizes with Newport’s 846HP bistable shutter to enable repeatable, accurate exposure control across holography, materials processing, spectroscopy, and laser-based experiments. The controller combines front-panel simplicity with advanced programmable functionality, supporting both timed and manual operation modes.
