High Speed Shutter Mechanism

Abstract

An electromechanical shutter for high speed spectroscopic studies is described. The device utilizes the energy of an electrically exploded metal foil to accelerate a movable slit, and propel it across a fixed slit. The minimum delay time is 19±2 μsec. A 20‐μ fixed slit may be opened and closed in 2 μsec by a 20‐μ moving slit. No medium is introduced into the optical path to alter spectral distribution.
