Waveguide sheet, fabrication method thereof and spectrometer using the same
First Claim
1. A waveguide sheet for a spectrometer, comprisinga first surface comprising a reflective layer;
- a first positioning side connected to the first surface, wherein the first positioning side is fabricated by a microelectromechanical (MEM) process and has a first surface feature formed by the MEM process, and the first positioning side is for a first spectral component of the spectrometer to abut against so that the first spectral component is positioned at the first positioning side; and
a first stray light elimination side connected to the first surface, wherein the first stray light elimination side is fabricated by the MEM process and has a second surface feature formed by the MEM process, and the first stray light elimination side is to be used as a side of a first stray light outlet,wherein the waveguide sheet is comprised of a MEM material.

Abstract
An fabrication method of a waveguide sheet for a spectrometer includes the steps of: providing a pattern to be performed by a microelectromechanical (MEM) process; and forming at least one waveguide sheet based on the provided pattern by the MEM process. The pattern includes a shape of a first waveguide sheet. The waveguide sheet includes at least one positioning side and at least one stray light elimination side formed by the MEM process. The positioning side is for a spectral component of the spectrometer to abut against so that the spectral component is positioned at the positioning side, and the stray light elimination side is to be used as a side of a stray light outlet. The structure of the waveguide sheet and the configuration of the spectrometer are also provided.
