Abstract

The invention relates to an optical switch, in particular to an ultra-silent mechanical free-space switching optical switch device, which aims to solve the rebound jitter and noise problems easily generated in the use of the existing electromagnetic relay mechanical optical switch. The ultra-silent mechanical free-space switching optical switch device comprises a base, wherein an iron core is vertically arranged on the upper surface of the base, and a stationary contact is arranged on the upper end surface of the iron core; a first spring is vertically arranged on the upper end surface of the stationary contact, and a movable contact is vertically arranged at the upper end of the first spring; and a connecting rod part is arranged on the upper surface of the base and comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, and a small-hole shading film is fixedly arranged at the other end of the first connecting rod. In the ultra-silent mechanical free-space switching optical switch device, the rebound jitter and noise problems easily generated in the use of the existing electromagnetic relay mechanical optical switch are effectively solved, and the optical switch device is suitable for quickly turning on or off laser propagated in a free space in various precision optical experiments.

Description

technical field [0001] The invention relates to an optical switch, in particular to an ultra-quiet mechanical free space switching optical switch device. Background technique [0002] The optical switch is a relatively important optical passive device, which can switch on and off the optical signal in the optical network system. At present, in optical network systems, optical switches based on various switching principles and implementation technologies are widely proposed. According to the switching medium of the optical switch, the optical switch can be divided into: free space switching optical switch and waveguide switching optical switch. Aiming at the problem of fast switching on and off of free-space propagating lasers in optical experiments, free-space switching optical switches commonly used at present include electromagnetic relay-type mechanical optical switches, semiconductor optical switches, acousto-optic and electro-optic switches. Among them, the switching ...
