The ColdQuanta microShutter is a high-performance chip-scale mechanical shutter designed for ultra-low SWaP laser shuttering applications, especially those sensitive to stray light. The microShutter features an integrated beam dump that traps light on-chip with normally open operation. Designed for direct integration in compact cold-atom quantum systems, the light and dark regions are physically separated to allow close integration into any system whose performance requires dark conditions to maximize performance. Product is under development. Please request additional information or updated specifications.
