Abstract
The invention provides a microlens array, which comprises a bottom lens layer and a plurality of paraboloids arranged on the bottom lens layer in alignment. The distance from a vertex of the paraboloids to a focus of the paraboloids is 0.280 to 0.550 mm. The microlens array has the advantages such as bright illumination and uniform imaging.
Description
Technical field
The present invention relates to the laser equipment field, be specifically related to converge and the microlens array of diverging light.
Background technology
Lens are optical elements that a kind of people are familiar with very much, and it belongs to passive optical component, in optical system, are used for assembling, the diverging light radiation.Common lens volume is bigger, and human eye can be seen, and belongs to the refractive optical element, follows refraction law, just can study their optical property well with the knowledge of geometrical optics.Identical lens have in one plane just constituted lens arra by certain periodic arrangement, and the optical property of the lens arra of being made up of common lens is exactly the synthetic of single lens function.Yet along with progress of science and technology, current instrument and equipment is towards light, mechanical, electrical integrated trend development.Not only manufacturing process is complicated to utilize the produced optical element of classic method, and produced optical element dimension is big, weight is big, can not satisfy the needs of current development in science and technology.At present; People can produce very little lens of diameter and lens arra; This lens and lens arra normally can not be by human eye identifications, have only with equipment such as microscope, ESEM, atomic force microscopes and just can observe, Here it is lenticule and microlens array.Advantages such as lenticule that the micro-optic technology manufactures and microlens array be little, in light weight with its volume, it is integrated to be convenient to, array have become new scientific research development direction.Along with the development trend of optical element miniaturization,, can produce lenticule and the lenticule battle array of diameter now for millimeter, micron even nanometer scale for the size that reduces lens and lens arra has been developed many new technologies.And different lenticule parameters has significant impact for lenticular converging with diverging light.Existing lenticule has improved the illumination uniformity coefficient and the lightness of laser greatly, but some occasion does not still reach requirement.
Summary of the invention
Technical matters to be solved by this invention is to provide microlens array, has advantages such as illumination is bright, imaging is even.
For solving above-mentioned existing technical matters, the present invention adopts following scheme: microlens array comprises the bottom lens layer, is located at the parabola of a plurality of marshallings on the bottom lens layer, the paraboloidal focus 0.280～0.550mm of said paraboloidal vertex distance.
As preferably, the paraboloidal focus 0.280mm of said paraboloidal vertex distance.
As preferably, the paraboloidal focus 0.325mm of said paraboloidal vertex distance.
As preferably, the paraboloidal focus 0.550mm of said paraboloidal vertex distance.
As preferably, the length of said bottom lens layer adopts 10mm, and width adopts 9.750～10mm, highly adopts 1.321～1.822mm, thereby has utilized the lenticular effect of converging and dispersing as wide as possible when the specific occasion needs reaching.
As preferably, the width of said bottom lens layer adopts 10mm, highly adopts 1.321mm.
As preferably, the width of said bottom lens layer adopts 9.750mm, highly adopts 1.700mm.
As preferably, the width of said bottom lens layer adopts 9.750mm, highly adopts 1.822mm.
As preferably, said paraboloidal bottom surface length adopts 1～1.429mm, and width adopts 0.750～1mm, thus make imaging more evenly, illumination is brighter.
Beneficial effect:
The microlens array that the present invention adopts technique scheme to provide can make laser imaging more even, and illumination is brighter.
