Embodiment Construction

[0025] like figure 1 As shown, a device for preparing different periodic gratings, including a guide rail base 1, a transmission shaft 2, a bearing slider 4, a PDMS fixed cover plate 5, and a limit side plate 6; there are two guide rail grooves under the bearing slider 4 , can straddle the two guide rails of the guide rail base 1; the PDMS fixed cover 5 is fixed with the bearing slider 4 and the guide rail base fixing part 3 through the PDMS fixing screws 7; the limit side plate 6 is fixed by the side plate Screw 8 is fixed with guide rail base 1. The size of the whole device can be adjusted at will, and the semicircular groove under the PDMS fixed cover can be adjusted according to the master material design.

[0026] The present invention also provides a method for using a device for preparing different periodic gratings, comprising the following steps:

[0027] Step 1: Remove the PDMS fixed cover (5), and place the two sides of the PDMS soft template with a grating struct...

Abstract

The invention discloses a device for preparing gratings with different periods and a using method thereof, and relates to the field of micro-machining. The device comprises a guide rail base, a transmission shaft, a bearing slide block, a PDMS fixed cover plate and a limiting side plate. When the device is used, the structured surface of the grating PDMS soft template is upwards fixed on the device bearing part, the bearing slide block moves away from the fixed part by adjusting the transmission shaft; the PDMS soft template is stretched so that the size of the periodic structures on the softtemplate is increased. The structured surface of the PDMS soft template is coated with the curing adhesive, a substrate is placed on the curing adhesive, then the adhesive is cured through a heating or exposure method, and the PDMS soft template is stripped after the adhesive is cured so as to obtain a grating structure with a required period on the substrate. Grating structures with different period sizes can be obtained by changing the stretching amount of the soft template. The device is easy to operate and convenient to use and can meet the requirement of copying gratings with different periodic sizes in batches at low cost.

Description

technical field [0001] The invention relates to the field of microfabrication, in particular to a device for preparing different periodic gratings and a method for using the same. Background technique [0002] A grating is an optical device composed of a large number of parallel slits of equal width and equal spacing. It can use the principle of multi-slit diffraction to disperse light and decompose it into a spectrum. sheet metal or glass. The earliest grating was made by Fraunhofer (Joseph Fraunhofer, 1787~1826) in 1821 with thin metal wires wound closely on two parallel thin screws to make a fine wire grating, a long period after Fraunhofer's death Over time, gratings developed slowly; in 1846, Friedrich Adolph Nobert (1806~1881) made a transmission grating with 240 lines / mm, but because of the manufacturing process, his grating could only be used as a teaching method. Tools; In 1870, Rutherford (LewisMerris Rutherfurd, 1816~1892) used his water turbine-powered scoring ...
