Abstract
A method for cutting optical element includes such steps as providing a bench, fixing an optical element to be cut onto the bench, cutting it to a predefined deepth, turning over the optical element, fixing it onto the bench, and cutting the residual tickness.
Description
[technical field]
The present invention relates to a kind of cutting method of optical element, especially relate to the cutting method of the meticulous optical element of a kind of cut surface.
[background technology]
Cutting processing is a common technology, along with the progress of science and technology, requires more and more higher for the planar condition of the cut end after the cutting.For optical element, its end face need have good precision to reduce the loss of light in transmission course, and promptly the end face of optical element should have good fineness, flatness and the uniformity.
Cutter commonly used cuts optical element in the prior art because cutter surperficial shear force difference in cutting process, easily cut surface produce collapse scarce, collapse rough surface phenomenon such as limit, therefore the quality to optical element produces very big influence.For eliminating this rough surface phenomenon, need carry out additional processing to the cut surface of this optical element, as operations such as grinding, polishings, therefore manufacturing process complexity not only, and can increase manufacturing cost.In addition, cutter is in cutting process, if depth of cut is darker, its suffered external pressure is bigger, makes that the cutter consume is more, thereby needs the frequent cutter of changing, and then increases cost.
In addition, the laser beam that the also useful laser equipment of prior art sends cuts, because laser beam has higher temperature, it can make the cut surface fusing of optical element and make the end face generation inhomogeneous.And disclosed Chinese invention patent application on August 15 calendar year 2001 discloses the cutting method of a kind of optical fiber that is disclosed for CN00133123 number, is to use carbon dioxide laser equipment to send light beam to cut in high energy short pulse mode.This carbon dioxide laser equipment can make the glass material distillation that is cut in cutting process, and then makes the end face after the cutting comparatively even.But this carbon dioxide laser equipment is than existing laser equipment costliness.
[summary of the invention]
For the shortcoming that cut surface is coarse in the cutting method that overcomes optical element in the prior art, cost is high, the invention provides the cutting method of the optical element that a kind of cut surface is meticulous, cost is low.
The technical scheme that technical solution problem of the present invention is adopted is: prepare a workbench; Optical element to be processed is fixed on this platform; This optical element is cut a desired depth; To be fixed on this platform after this optical element upset; The aligning cutting position is cut this optical element and is worn.
Compared with prior art, the invention has the beneficial effects as follows: because on a surface of this optical element, cut a desired depth earlier, again its upset back is cut it from the correspondence position of its opposite face and wear, the cutting pressure that is applied than whole cut when wearing little, therefore be difficult for producing on the cutting surface collapse scarce, collapse rough surface phenomenon such as limit, and machining accuracy is higher, grinding that need not postorder, operations such as polishing, so processing procedure is fairly simple, cost is lower.In addition, cutter is in cutting process, and its suffered external pressure is little, so the cutter consume is less, need not frequently to change cutter, and then saves cost.

[specific embodiment]
The flow chart of the cutting method of optical element of the present invention as shown in Figure 1.At first prepare a workbench; Optical element to be processed is fixed on this platform; This optical element is cut a desired depth; To be fixed on this platform after this optical element upset; Along relative cutting position this optical element is cut and to be worn, promptly finish the cutting of this optical element.
Fig. 2 is interelement stereogram in the cutting process of optical element of the present invention to Fig. 5.As shown in Figure 2, at first prepare a workbench 10, then optical element to be processed 20 is fixed on this workbench 10.Wherein this workbench 10 can adopt the glass platform of hard nothing distortion, and it has level and smooth surface; The stainless steel platform of also available hard nothing distortion, it has good surface smoothness.This optical element 20 has a upper surface 21 and a bottom surface 22 with respect to this upper surface 21, can adopt modes such as vacuum suction, double faced adhesive tape bonding and anchor clamps are fixing to fix between this bottom surface 22 and the workbench 10.Wherein the double faced adhesive tape that the time adopted of double faced adhesive tape bonding can be UV epoxy resin, and its adhesion strength is strong and to move back glue easy, will guarantee that when gluing the cemented surface of bottom surface 22 and workbench 10 is evenly level and smooth, no gap.In addition, with the stainless steel anchor clamps that the anchor clamps that adopted in the anchor clamps fixed form can adopt hard nothing to be out of shape, it can be fastening with optical element 20.
Fig. 3 is the stereogram with optical element 20 cuttings one desired depth.At first cut out a grooving 23 with cutter 30 on the upper surface 21 of optical element 20, this grooving 23 has a desired depth h, and this degree of depth h can be 1/5th to 4/5ths of these optical element 20 thickness.This cutter 30 can be has the uniform diamond cutter in high-precision surface.
Again as shown in Figure 4, upper surface 21 is fixed on the workbench 10 after optical element 20 is turned over turnback.Wherein the fixed form of upper surface 21 and workbench 10 can adopt fixed forms such as vacuum suction, double faced adhesive tape bonding and anchor clamps are fixing equally.
And for example shown in Figure 5, along the relative position of grooving 23 it is cut at a bottom surface 22 of optical element 20 with cutter 30 and to wear, promptly finish the cutting process of this optical element 20.
Wherein this optical element 20 can be fragile material element, surface coating element or the heavily stressed element of tool, as LGP, glass substrate, lens and film filter etc.The cutting method of this optical element 20 only with carrying out two-sided cutting after its upset, therefore can obtain the good cutting element of cut surface.In addition, the cutting of these optical element 20 any angles also can be adopted flow chart manufacturing shown in Figure 1.
In addition, the two-sided cutting method of optical element 20 of the present invention with directly cut the single face cutting method of wearing at upper surface 21 and compare, because the depth of cut of cutter 30 is more shallow, can reduce the lasting stressed of this cutter 30, and then prolong service life of this cutter 30, and because can two-sidedly cut, contrast identical cutter 30, its processing thickness is the twice of single face cutting processing thickness.In addition,, need not frequently to change cutter, and then save cost because cutter 30 consumes are less.
