Embodiment 1

[0026] (1) Preparation of primary microchannel plate:

[0027] A number of hollow fibers are regularly arranged as regular hexagonal hollow fiber bundles, and the regular hexagonal hollow fiber bundles are fused at a temperature of 620°C, and edged glass is added to the outer surface after fusion, and the pore diameter of the obtained primary microchannel plate is 50um;

[0028] (2) Fill primary microchannel plate for post-processing:

[0029] The polymer filler was melted at a temperature of 120°C. Under the constant temperature condition of 90°C, the viscosity coefficient of the heated and melted polymer filler was measured by a rotational viscometer to be 78mPa.s, and the viscosity coefficient of the heated and melted polymer filler was The volume thermal expansion coefficient is 0.75×10 -3 / °C, fill the melted and easy-to-fill polymer filler into the primary microchannel plate; cool for a period of time until the polymer filler is solidified, the solidified polymer filler...

Abstract

The invention provides a method for preparing a microchannel plate with a polymer filler, which relates to the technical field of micro-optical element manufacturing. The invention melts the polymer filler into a liquid state and fills it into the pores of a primary microchannel plate prepared by a hollow core method, and solidifies Afterwards, a post-treatment process is carried out, and finally it is removed with an organic solvent to obtain a finished microchannel plate. The invention effectively prevents the cracking and deformation of the microchannel plate prepared by the hollow core method in the post-treatment process through the filling effect of the polymer filler.

Description

technical field [0001] The invention belongs to the technical field of manufacturing micro-optical elements, and in particular relates to a method for preparing a micro-channel plate with a polymer filler. Background technique [0002] Microchannel Plate (MCP for short) is a microwell array element with electron multiplication effect, due to its high gain, low noise, high resolution, wide frequency band, low power consumption, long life and self-saturation effect Features, and are widely used in low-light image tubes, photomultiplier tubes, camera tubes, and particle detectors. [0003] At present, the preparation method of MCP is mainly the solid acid dissolution method. The key to the preparation of MCP by this method is that the glass fiber used is formed by drawing together a core glass rod and a jacket glass tube that can be etched by acid. The two kinds of glass The fibers are regularly arranged in bundles, fused at high temperature and cut into thin glass sheets, and...
