Problems solved by technology

It has several shortcomings: First, in order to correct high hyperopia or nearsightedness, the lenses are often too thick and heavy; therefore, the maximum diopter of hyperopia and myopia lenses currently available on the market is D=+4.0m -1 (Hyperopia 400 degrees) and D=-4.0m -1 (myopia 400 degrees)
The second is that some people (su

Embodiment 1

[0027] Example 1. This example is +7.0m -1 The design and manufacturing process of hyperopia lenses, using a pair of molds, of which +3.0m -1 Formed by the mold surface of ordinary hyperopia lens, +4.0m -1 Formed by the surface of the micro-optical replication mold, the design and production methods of the micro-optic replication mold are as follows:

[0028] 1) Photolithography mask: According to the principle of optics, the diopter is +4.0m -1 The focal length of the hyperopia lens is f=200mm, and the optical aperture parameter is 30mm. Using photoresist ( # 1350) photolithographic chromium plate, using electron beam lithography machine or laser direct writing equipment to make three masks according to the software designed according to (A), the minimum line width of the edge is controlled to 1 μm, and the ring diameter is gradually increased to r k =(2kλf) 1 / 2 , where the number of rings K=1, 2, 3...λ-wavelength of incident light, f-focal length.

Embodiment 2

[0032] Example 2. This example is +6.0m -1 The design and manufacturing process of hyperopia and +200 degree astigmatism lens. Comparing with Example 1, in the designed software, substitute corresponding parameters, according to meridian plane+6.0m -1 Focus length design microstructure, according to the sagittal plane +2.0m -1 The focal length designs the microstructure and makes it on the mask to make a pair of manufacturing molds.

Abstract

This invention relates to microoptical eyeglass design and process technology and its glass including 1) photoengraving mask: to determine focal distance according to diopter, to determine and computer (x,y) perameters to photoengrave I(x,y) to corresponding several masks in terms of optical holes. 2) ionic etching; to etch sample several times of ionic etching with mask orderly to get 3-D microoptical glass structure with related step depth. The said mask can be formed according to meridional plane to design one focal distance and according to sagisttal plane to design the other focal distance, characterizing in the embossed sample and ionic etching is carried out on each side of the sample.

Description

technical field [0001] The invention relates to glasses and a manufacturing process thereof, in particular to a design and manufacturing process of a micro-optic eyeglass lens and the lens thereof. It uses the combination of micro-optics diffraction and conventional lens refraction optics to form a new generation of glasses - micro-optic glasses. Background technique [0002] Spectacles currently on the market use the refraction of optical lenses, that is, the curvature and refractive index to image, so as to satisfy the refractive errors of different human eyes. It has several shortcomings: First, in order to correct high hyperopia or nearsightedness, the lenses are often too thick and heavy; therefore, the maximum diopter of hyperopia and myopia lenses currently available on the market is D=+4.0m -1 (Hyperopia 400 degrees) and D=-4.0m -1 (myopia 400 degrees). The 2nd, some people (as presbyopia myopia, myopia presbyopia) must put on and take off or change another pair o...
