The image by a gas lens of laminar flow type is experimentally analyzed with the optical transfer function. The variation of the line spread function of the gas lens is measured as a function of variables and parameters (temperature, wind velocity, distance) concerned with imaging cction of the gas lens. The focal length of the gas lens is also measured by the use of the line spread function. Further, the space frequency which gives the first zero point of the optical transfer functions is obtained from the line spread function and image of Simens-star, and discussion is made on the space frequency bandwidth of the gas lens.
