Abstract

一种具有杂散光滤除构造（20）的微型光谱仪，包括输入部（10），杂散光滤除构造（20）和微型绕射光栅（30）。输入部（10）接收处于预设角度内的第一光信号（S1）和处于预设角度外的第二光信号（S2）。杂散光滤除构造（20）用于滤除第二光信号（S2），并且包括第一过滤区段（22）和第二过滤区段（24）。第一过滤区段（22）和第二过滤区段（24）具有相对设置的齿状结构（22T，24T），两个齿状结构（22T，24T）之间限定出一光通道（26）以使第一光信号（S1）通过，滤除第二光信号（S2）。微型绕射光栅（30）接收通过杂散光滤除构造（20）的第一光信号（S1），并将第一光信号（S1）分离成多个光谱分量。
