Description
Technical field
The present invention relates to a kind of grating, and in particular to a kind of Bragg diffraction bigrating structures design side of Rowland circle structure
Method.
Background technology
Grating is needed to use in the field for much needing light to reflect, grating can be reflected light, used
To the place of grating the refraction of light can be allowed more good, more stable when grating is used, many gratings exist
It is not very bright place especially in light using not very convenient when needing light to reflect when use, shadow
Rung the further use of grating, the working effect of part grating is affected, have impact on grating workplace use and
Stable, it is not that good diffraction goes out outside grating when diffraction to cause grating.

The technical scheme is that：A kind of Bragg diffraction bigrating structures design methods of Rowland circle structure, are provided with
Shell, link slot is provided with described shell, several grating columns, described grating are installed with described link slot
Column is set gradually along link slot, and printing opacity gap, described printing opacity gap length point are provided between described grating column
Cloth is in the both sides of grating column.
Described grating column is cylindrical-shaped structure, and grating column is fixed in link slot.
Integrally formed structure is interconnected to form between described link slot and shell, is provided with the top of link slot outer
Shell.
Described shell is divided into upper case and lower case, and link slot is provided with upper case, is set in link slot
It is equipped with grating column.
Rebound is provided with described lower case.
Described rebound and the mutual connection of lower end case, rebound upper end are connected with each other with grating column.
Described grating column is provided with scattered seamed edge.
Described scattered seamed edge is arranged on the both sides of grating column.
It is an advantage of the invention that：Scattered seamed edge is provided with grating column, can allow grating column diffraction more
It is convenient and efficient, the easy to use of different operating modes is disclosure satisfy that, the working effect of diffraction can be allowed more good, can be in difference
The work stablized in environment, grating column is arranged in link slot, link slot fixed grating column can be allowed more
It is convenient and firm.
