Abstract Broad band hyperspectral camera can more comprehensively record the spectral
information of the target, which is one of the main directions pursued by the hyperspectral
camera at present. However, the broad band is bound to cause problems with excessive
chromatic aberration and secondary spectra of the system, which will affect the image
quality. Therefore, based on the analysis method of Buchdahl vector dispersion model, this
paper proposes a optical system of broad band hyperspectral camera based on linear variable
filter. An image side telecentric transmitted optical system with a focal length of 100mm, F
