Embodiment 1

[0028] The realization of a compound eye structure with a supersmooth surface prepared by a femtosecond laser comprises the following steps:

[0029] (1) As attached figure 1 As shown, the femtosecond laser system 1 generates a Gaussian laser with a wavelength of 800nm, a pulse width of 50fs, and a repetition frequency of 1kHz. The energy of the laser is changed through the attenuator 2, and the on-off of the mechanical switch 3 is controlled by the computer system 11, and the dichroic The mirror 7 changes the direction of the laser light, so that the laser light is vertically incident on the microscope objective lens 8 (50×, NA=0.6); the femtosecond laser beam focused by the objective lens is irradiated on the surface of the sample 9, which is fixed on the six-degree-of-freedom translation stage 10; During this process, the white light emitted by the white light source 5 passes through the beam splitter 4, the dichroic mirror 7, and the microscope objective lens 8 to irradiat...

Abstract

The invention relates to a compound eye structure prepared based on a femtosecond laser and provided with a super-smooth surface, and belongs to the technical field of laser application. The machiningmethod of the compound eye structure comprises the following steps of: carrying out femtosecond laser point-by-point scanning on the surface of glass with a concave spherical surface to form a micro-pit defect array, then etching a glass sample by adopting a hydrofluoric acid (HF) solution to obtain a glass sample with a micro-concave lens array, then machining a porous micro-nano composite structure surface on the sample by utilizing the femtosecond laser again, re-etching the shape of the porous micro-nano composite structure surface by using polydimethylsiloxane (PDMS) by taking the porousmicro-nano composite structure surface as a template to obtain a compound eye structure provided with a porous micro-nano composite structure on the surface, and pouring silicone oil on the micro-nano composite structure surface to obtain a compound eye structure with a super-smooth surface. The machining method of the compound eye structure is high in efficiency, the removal amount of materialsdoes not need to be accurately controlled, and a simple, efficient, good-durability and wide-application-range scheme is provided for clinical endoscopic surgery.

Description

technical field [0001] The invention relates to a compound eye structure with a supersmooth surface prepared based on a femtosecond laser, and belongs to the technical field of laser applications. Background technique [0002] Endoscopes are widely used in the medical field, and a clear field of view is crucial to the safety and efficiency of endoscopic surgery. Therefore, maintaining clear imaging of endoscopes in the body has important clinical application value. There are generally three causes of impaired endoscopic field of view: condensation of fluid on the surface, contamination of blood or interstitial fluid, and scratching of the surface by surgical equipment. Since the external temperature is usually lower than the internal temperature and the internal humidity is relatively high, the endoscope will instantly fog when it enters the body; compared with the fogging of the endoscope lens, blood or tissue fluid contamination is often sudden, but not uncommon, Especial...
