一种基于窄带滤光片体制的高速光选仪
By using a high-speed optical sorter based on a narrowband filter system, combined with a front optical full-spectrum achromatic image-side telecentric lens and a multi-spectral beam-splitting narrowband filter, the problems of limited optical sorting spectrum, low resolution, and low light throughput in existing optical sorting equipment are solved, achieving efficient multispectral screening.
