Abstract
We report an optical design for a low-cost optics, broadband, astigmatism-corrected practical spectrometer. An off-the-shelf cylindrical lens is used to remove astigmatism over the full bandwidth. Results show that better than 0.1 nm spectral resolution and more than 50% throughput were achieved over a bandwidth of 400 nm centered at 800 nm.
摘要
我们报道了一种用于低成本光学元件、宽带、像散校正实用光谱仪的光学设计。使用一个现成的柱面透镜在整个带宽上消除像散。结果表明，在以800nm为中心的400nm带宽上实现了优于0.1nm的光谱分辨率和超过50%的通量。
