Abstract

The invention provides a high-throughput large-aperture high-precision lens four-dimensional on-line focus controlling device, which relates to a lens on-line focus controlling device and solves the problem that a special lens regulating mechanism for carrying out three-dimensional precise regulation is lacking. In the high-throughput large-aperture high-precision lens four-dimensional on-line focus controlling device, a lens is arranged in a lens frame which is arranged in a lens frame runner, the lens frame runner is connected with a lifting frame, the lifting frame slides in a first guide rail and a second guide rail in the vertical direction, and a horizontal frame slides in a third guide rail and a fourth guide rail in the transverse direction. The high-throughput large-aperture high-precision lens four-dimensional on-line focus controlling device disclosed by the invention is applied to lens on-line focus control.

Description

technical field [0001] The invention relates to a lens online focusing device. Background technique [0002] In the inertial confinement laser fusion device, the terminal optical assembly is located at the end of the entire laser chain, including a variety of large-diameter optical elements and their controls, transmission systems and complex mechanical structures. system. The terminal optical component of the Shenguang-Ⅲ prototype device is a laser target injection system, which includes multiple functions such as laser shaping, laser frequency doubling, laser beam focusing injection, parameter sampling, and target fragment shielding. This component can be divided into two relatively independent modules, namely the frequency doubling module and the lens module. Among them, the spatial position accuracy of the shooting lens in the lens module is relatively high, and a special lens adjustment mechanism is required for three-dimensional precision adjustment to meet the speci...
