Abstract

The present invention provides a micro-channel plate, a preparation method therefor and the use thereof. The micro-channel plate is provided with a plurality of through channels, wherein on the side of an inlet end face of the micro-channel plate, a flared end face of each channel is a hexagonal tapered hole; and in a cross section perpendicular to the axial direction of each channel, the outer edge of the flared end face of the channel is hexagonal, and the inner edge thereof is circular. The present invention provides a micro-channel plate having hexagonal special-shaped flared holes, which micro-channel plate has a micro-hole array presented as hexagonal tapered holes on an end face and cylinders inside; a circular packed array is replaced by a hexagonal close-packed structure, so that the close packing coefficient of a channel array of the micro-channel plate is increased from 0.907 in existing hexagonal arrangements of circular channels to 1 in the hexagonal arrangement of hexagonal channels, and when the channel wall thickness of the channel of the micro-channel plate at the flared end face is greater than or equal to 100 nm, the opening ratio of the micro-channel plate is greater than or equal to 91%. The opening ratio of an input surface of the micro-channel plate is significantly increased, the detection efficiency of the micro-channel plate regarding input signals is improved, and flared tips and tip discharge caused thereby are avoided, such that the micro-channel plate is more suitable for practical application.

Abstract

A support column array having a variable elastic modulus, and a vacuum glass. A first ring of support columns in the variable elastic modulus support column array close to a sealed edge of the vacuum glass comprises low-elastic modulus support columns. A second ring of support columns close to the sealed edge of the vacuum glass comprises high-elastic modulus support columns. In this manner, rings of low elastic modulus support columns and rings of high elastic modulus support columns are alternately arranged in a direction leading away from the sealed edge of the vacuum glass, until the support columns are all arranged. The vacuum glass is formed from the varying elastic modulus support column array and flat glass. The varying elastic modulus support column array reduces the maximum stress and the maximum deformation sustained by the vacuum glass, thereby reducing glass damage and missing support columns. The arrangement of the varying elastic modulus support columns can be applied without changing the original array spacing of support columns of existing products, or using the array spacing of support columns in novel designs.

Abstract

A vacuum melting furnace for infrared glass, includes an upper furnace body and a lower furnace body that can be connected with each other or isolated from each other. Vacuum melting of the infrared glass is achieved in the upper furnace body wherein the influence of water in the environment is eliminated. The vacuum negative pressure environments can promote separation of hydroxyl in the structure, which achieves removing of hydroxyl in the glass, and then discharging of the molten infrared glass is conducted at atmospheric pressure in the lower furnace body. By using the vacuum melting furnace for infrared glass, infrared glass with good spectrum transmission performance can be obtained with improved property stability and optical homogeneity, which facilitates the preparation and molding of large sized and special-shaped infrared glass products.
