The MKS Instruments/Newport 845HP-01 is a precision digital shutter controller engineered for accurate timing and modulation of optical shutters in research and industrial applications. It delivers sub-3 millisecond response times with exposure durations from 10 milliseconds to 990 seconds, coupled with ±0.05% + 10 μsec timing accuracy. The system handles optical power up to 5 W CW and operates at maximum repetition rates of 10 Hz, making it suitable for demanding photonics environments including holography, laser experiments, and precision optical alignment.
