Background technique
Currently, diffraction grating is usually to be processed one by one according to design size, it is time-consuming and laborious, such as diffraction grating product is usual
It is made of the method for duplication, in traditional diffraction-grating replica technique, one piece of diffraction grating mother matrix single can only be produced
One piece of lenticular product.Output efficiency is low.And with the development of science and technology cutting technique is increasingly mature, by multiple diffraction grating according to
It is centainly sequentially prefabricated into monolith, then single diffraction grating should be obtained by cutting processing and be possibly realized.
Since diffraction grating has fine surface relief structure, easily damages, in cutting processing, cut the powder of generation
Used cutting fluid can all cause irremediable damage to diffraction grating when dirt and cutting, so, use cutting machine-cut
It needs first to protect diffractive grating surface when cutting diffraction grating.
But in the prior art, the method for not yet finding the energy effective protection diffractive grating surface in diffraction grating cutting,
It cannot achieve the lossless cutting of diffraction grating.
Summary of the invention
It is an object of the invention to propose a kind of lossless cutting method of diffraction grating, can be protected in diffraction grating cutting
Shield grating surface is injury-free, and then realizes the production of efficient, high quality diffraction grating.
To achieve the above object, the application provides a kind of lossless cutting method of diffraction grating, includes the following steps:
S1, in the paraffin that diffractive grating surface drop coating is melted；
Protection glass is bonded on paraffin by S2；
S3 after paraffin solidification, diffraction grating and protection glass is fixed on cutting machine, protect glass towards cutter；
S4, cutting diffraction grating and protection glass；
The diffraction grating of well cutting and protection glass are put into dissolve in the organic solvent of paraffin and be impregnated by S5, paraffin
After dissolution, diffraction grating is taken out.
Preferably, in the step S1, the paraffin is 58 degree of industrial paraffin particles (or other types paraffin), will be placed
The container of paraffin particles is heated to 60 DEG C and maintained until drop coating is in diffractive grating surface after paraffin particles whole thawing.
Preferably, in the step S2, it is described protection glass with a thickness of 1-3mm.
Preferably, the protection glass is optical glass, and area is identical as the area of diffraction grating.
Preferably, in the step S3, diffraction grating and protection glass are fixed on the mode on cutting machine as vacuum suction.
Preferably, in the step S3, diffraction grating and protection glass are fixed on the mode on cutting machine as paraffin bonding.
Preferably, in the step S3, diffraction grating and protection glass are fixed on the mode on cutting machine and fix for fixture.
Preferably, in the step S5, the organic solvent is dehydrated alcohol.
Preferably, in the step S5, the organic solvent is petroleum ether.
Preferably, in the step S5, the organic solvent is acetone or the solvent of other same types.
Compared with prior art, the invention has the following advantages:
Because being spotted with one layer of paraffin in diffractive grating surface, (this type paraffin can play bonding grating and protection glass
While glass, diffractive grating surface is not damaged, easy to clean), and it has been bonded one layer of protection glass, it can be to avoid in the mistake of cutting
Cheng Zhong, cuts powder and cutting fluid contacts diffractive grating surface, causes to damage to diffraction grating.After completing cutting, using having
Solvent can effectively wash paraffin, separation diffraction grating and protection glass, without causing to damage to diffractive grating surface
Wound.The lossless cutting method of diffraction grating provided by the invention, simple process, material is easy to get, is less toxic, low in cost, is cutting
In the process, energy effective protection grating surface is injury-free, realizes the production of efficient, high quality diffraction grating.
