ASSEMBLING METHOD OF SPECTROMETER AND ASSEMBLING SYSTEM

摘要

A spectrometer comprising a waveguide module, a diffractive component, and a light sensor is provided. The waveguide module has a first reflective surface, a second reflective surface opposite to the first reflective surface, and a light channel between the first reflective surface and the second reflective surface. The diffractive component has a diffractive surface and a plurality of strip-shaped diffractive structures located on the diffractive surface. The sharpness of the profile of the strip-shaped diffractive structures on a first side of the diffractive surface is greater than that on a second side of the diffractive surface. When viewed along a direction perpendicular to the second reflective surface, the first side of the diffractive surface is positioned between the first reflective surface and the second reflective surface with a distance away from the second reflective surface. A method for assembling the spectrometer and an assembling system are also provided.

1. A method for assembling a spectrometer, comprising:
disposing a diffractive component along a side of a light channel of a waveguide module, wherein the waveguide module comprises a first reflective surface and a second reflective surface opposite to the first reflective surface, wherein the light channel is located between the first reflective surface and the second reflective surface, and wherein the diffractive component has a diffractive surface; disposing a light sensor on one end of the light channel; transmitting light to the diffractive surface via the light channel such that at least a portion of the light is diffracted into diffracted light by the diffractive surface and the diffracted light is incident on the light sensor; adjusting at least one of a position of the diffractive surface along a direction substantially perpendicular to the second reflective surface or an angle between the diffractive surface and the second reflective surface, and measuring a corresponding spectrum of light incident on the light sensor; determining whether the spectrum of the light incident on the light sensor meets a predefined first sharpness condition; and securing the diffractive component when the spectrum of the light incident on the light sensor meets the predefined first sharpness condition; or adjusting either or both of the position and the angle of the diffractive surface until the spectrum of the light incident on the light sensor meets the predefined first sharpness condition.
