Description
Technical field
This application involves the technical field of diffraction grating protection, in particular to diffraction grating in a kind of storage, transportational process
Guard method.
Background technique
It is easily impaired since diffraction grating has fine surface relief structure, therefore, in storage, transportational process, no
Only the vapor in air, the saliva of operator, finger sweat can pollute diffractive grating surface, and diffraction grating is by outer
The case where power squeezes all can cause diffraction grating to form irremediable damage.Existing grating generallys use after packing box is packed again
Storage and transport.But grating surface is an exposure in air, is easy the erosion by water vapor in air.So storage,
It is very necessary for carrying out protection to its surface first when transporting diffraction grating.
In the prior art, the method for not yet finding to be capable of effective protection diffraction grating in storage, transport, cannot achieve and spread out
Penetrate the effective protection of grating.
Summary of the invention
It is an object of the invention to propose a kind of guard method of diffraction grating, when can store, transport in diffraction grating
Protect grating surface injury-free.
To achieve the above object, the application provides a kind of guard method of diffraction grating, includes the following steps:
S1, by paraffin melting at liquid；
S2, by the paraffin drop coating of thawing in diffractive grating surface；
Protection glass is bonded on paraffin by S3；
S4, after paraffin solidification, diffraction grating and protection glass are stored as a whole, are transported；
S5 needs to rush in use, diffraction grating and protection glass are put into impregnate in the organic solvent that can dissolve paraffin
It washes, after paraffin dissolution, takes out diffraction grating.
Preferably, in step S1, the paraffin is 58 degree of industrial paraffin particles (being also possible to other kinds of paraffin), will
The container for placing paraffin particles is heated to 60 DEG C and maintained until paraffin particles are all melted.
Preferably, in the step S3, it is described protection glass with a thickness of 1-3mm.
Preferably, protection glass is optical glass, and area is identical as the area of diffraction grating.
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 paraffin can meet bonding diffraction grating simultaneously and protect
It protects glass and does not damage the requirement of the function of diffractive grating surface, and is easy to clean.), and it has been bonded one layer of protection glass, it can
To avoid vapor, the saliva of operator, the sweat of finger and other objects during storage, transport, in air
Diffractive grating surface is contacted, diffraction grating is caused to damage, when needs using diffraction grating, is impregnated using organic solvent,
Paraffin can be effectively washed, diffractive grating surface will not be caused to damage.The protection side of diffraction grating provided by the invention
Method, simple process, material is easy to get, is less toxic, low in cost, and in cutting process, energy effective protection grating surface is injury-free, real
The production of now efficient, high quality diffraction grating.
