Abstract
The present report describes the first results obtained in the analisys we are carring out on some infrared narrow band filters for astronomy. The observations with the Infrared camera ARNICA at the TIRGO telescope have shown some problems in the use of this kind of filters; particulary the transmission is not uniform over the whole field of the camera and circular features are observed. Laboratory measurements were carried out in order to understand this behaviour.
