Laser shutter

Overview

Stanford has recently launched two kinds of optical shutter control systems: sr470 laser shutter controller and sr474 four channel laser shutter driver. These laser shutter systems can minimize vibration. Its uniquely designed shutter can be controlled by these two controllers respectively. Sr470 provides a single time signal to a chopper head; The sr474 can drive four chopper heads at the same time, and can carry out external time control. The main performances are: ultra-low vibration fast door head, real mechanical laser beam on-off, more than 10m service life, microprocessor control timing, modulation frequency from DC to 125Hz (arbitrary duty cycle), can cooperate with 3mm aperture, GPIB, RS-232 interface and network interface.
