VTT has previously developed Fabry-Pérot interferometer-based hyperspectral cameras which have been fixed focal length cameras. In some applications it would be beneficial to have zoom capability to first search the target and then zoom in to the target to collect the data. This paper describes hyperspectral camera design with zoom optics and first test result of the camera. Hyperspectral camera has two operation modes; wide mode and tele mode. Optics design is done so that only one lens group need to move which makes mechanics and operation of the camera simpler.
