A gas lens of laminar flow type is made with which preliminary experiments is performed. Experiments ascertain that there exists an imaging action in this type of gas lens. Two kinds of experiments are conducted to confirm this action. One is to make real images with a gas lens and another to constitute a telelescope using a gas lens. In the former experiment, real images are produced by changing not only the distance between the gas lens and the imaging plane butalso the temperature. gradient of the gas lens. In the latter experiment, a Keplerian telescope is: made with the use of the gas lens for an object lens and a concave mirror for an eye lens. Fairy good photographs are obtained.
