Abstract

A multifunctional optical micro-manipulation device comprises a femtosecond laser, an optical tweezers laser, an optical system, a stage, a light source system, an imaging system, a spectral measurement system and a computer, wherein the optical system comprises a shutter, an attenuator, a focusing lens, a near IR reflector and a microscopic objective lens; the light source system comprises an illumination light source and a condenser lens; the microscopic objective lens is arranged on the stage for condensing a laser beam emitted by a laser generator onto a sample; the condenser lens is arranged below the stage for condensing a visible light emitted by the illumination light source onto the sample; and the imaging system includes an IR filter and CCD camera sequentially disposed on the projection light path of the near IR reflector. By integrating three functions of laser tweezers, femtosecond laser scissors and microspectrometer in one system, the invention can overcome the singleness and the disadvantages of the prior laser micro-beam technology and can be widely used for studying in biological, medical, biophysical, material chemistry and nano-technology fields.

Description

technical field [0001] The invention relates to an optical micromachining and measuring device. Background technique [0002] Optical micro-manipulation technology refers to the technology that uses optical methods to conduct fine manipulation and characteristic research on tiny particles, mainly including laser optical tweezers technology, laser light knife technology, and microspectral measurement technology. [0003] Laser optical tweezers is a new type of micro-manipulation method, which uses the mechanical effect of light. Different from traditional mechanical systems, its clamping and moving of tiny "workpieces" (such as biological cells, organelles and other tiny particles) are realized by laser, which is a micro-manipulation without any mechanical contact. The basic principle of laser optical tweezers is to use the gradient force formed by the spatial variation of the light field intensity to stably capture the particles at the strongest point of the light field, th...
