Abstract
Various compact spectrometer configurations have been proposed to reduce size. But due to the mismatch between the size and the focusing, optical aberration and poor spectral resolution occur. This work reports an aberration correction lens with a transmission grating (ACLG) based compact spectrometer that improves spectral resolution. It is packaged with an assembly of top, bottom parts, and middle ACLG parts, the overall thickness of the spectrometer is 10mm and has an average resolution of 2nm over a wide range of 500 to 1000nm. This compact spectrometer with high performance can serve as a core device of handheld or portable analysis equipment.
