Paper Abstract

The resolution of spectrometer can be increased by using multiple detectors. But for the portable spectrometer, the relatively wide edge that used to fix the detector can seriously influence the imaging quality. And the multiple detectors will increase the difficulty of the circuit part. In this paper, a novel method is introduced to increase the resolution by using one detector. The whole waveband is divided into two wavebands in this new structure. And the long waveband will be reflected by a mirror to the definitely location in which the short wave is located. This structure will not only solve the influence of the detector’s edge but also lower the cost of circuit part. By the simulation of the ZEMAX, the resolution of the spectrometer using the new method is better than the current works using one detector in the whole waveband.
