Do-it-yourself VIS/NIR pushbroom hyperspectral imager with C-mount optics

This paper describes a new optomechanical design based on a previously presented do-it-yourself pushbroom hyperspectral imager (HSI) using commercial off-the-shelf (COTS) components. The new design uses larger aperture C-mount at F/2.8 instead of S-mount optics at F/4 to increase the throughput, which allows imaging at lower light levels. This is especially useful for dark surfaces like the deep ocean. The improved throughput is 6.77 higher at...
