Paper Abstract

The development of light-weight instrumentation for space-based measurements, involves an improvement in the production techniques of optical components. In this work the design and manufacturing of small-dimension variable filter is described. These visible-infrared filters are designed to be coupled to an array detector, in a way that each CCD line is able to detect the radiation in a different narrow radiation band. In this way a compact low-mass optical sensor is obtained that will be combined to a telescope for image spectrometry from space. The optical filters were manufactured by radiofrequency magnetron sputtering, with the aid of a masking system inside the vacuum chamber. Testing at cryogenic temperature proved their stability in the space environment conditions.
