A miniature optical spectrometer with a thin-film planar waveguide grating coupler in combination with a miniature plano-convex focusing lens has been investigated. With optical part of the spectrometer as small as 0.2 cubic cm, the spectral resolution varies from 0.3 nm to 4.6 nm within the wavelength range 488.0 nm - 632.8 nm.
研究了一种带有薄膜平面波导光栅耦合器并结合微型平凸聚焦透镜的微型光学光谱仪。该光谱仪的光学部分小至0.2立方厘米，在488.0纳米至632.8纳米的波长范围内，光谱分辨率在0.3纳米至4.6纳米之间变化。
