Paper Abstract

It is necessary to optimize the slit width of a spectrometer in order to obtain the theoretical resolution, the greater amount of energy onto the detector and a better signal to noise ratio. We propose a transformer system of images for spectroscopy, which consists of a plano-convex lens cemented on one side of a parallel-plane glass plate, to transform the image formed in the focal plane of a telescope into an image of rectangular form of a specific size, with the objective that all the light passes the slit of the spectrometer without decreasing the resolution. We present the preliminary simulations and experimental results of the proposed optical system.
