Abstract
A torsion balance is provided which includes a twisting wire and a reflector. The twisting wire is a suspended carbon nanotube. The reflector is hung on the twisting wire. The reflector further includes a film, a first reflecting layer, and a second reflecting layer; and the film includes a first surface and a second surface opposite to the first surface, and the first reflecting layer is located on the first surface and the second reflecting layer is located on the second surface.
Claims16
A torsion balance, comprising:
- a twisting wire being a suspended carbon nanotube;
- and
- a reflector hung on the twisting wire, wherein the reflector comprises a film, a first reflecting layer, and a second reflecting layer;
- and the film comprises a first surface and a second surface opposite to the first surface, and the first reflecting layer is located on the first surface and the second reflecting layer is located on the second surface.
A method for making a torsion balance, comprising:
- S1, providing a substrate, wherein a space is defined on a surface of the substrate;
- S2, forming a first film preform on the surface of the substrate, wherein the first film preform is suspended on the space to cover the space;
- S3, cutting the first film preform to obtain a second film preform, wherein the second film preform comprises a first portion, a second portion opposite to the first portion, and a middle portion located between the first portion and the second portion;
- and the first portion and the second portion are fixed on the surface of the substrate and supported by the substrate, and the middle portion is suspended on the space;
- S4, providing a carbon nanotube crossed and fixed with the second film preform, wherein the carbon nanotube comprises a first end and a second end opposite to the first end, the first end and the second end are contacted with the surface of the substrate;
- S5, cutting the second film preform to obtain a film hung on a surface of the carbon nanotube, the film comprises a first surface and a second surface opposite to the first surface;
- and
- S6, forming a first reflecting layer on the first surface of the film, and forming a second reflecting layer on the second surface of the film.
