Abstract: PROBLEM TO BE SOLVED: To provide the subject device with a low cost and a characteristic to cover a wide dynamic range by providing a light quantity attenuator in a light path of standard light, and attenuating the light quantity level of the standard light through the continuous change of cross section of beam of the standard light. SOLUTION: A standard light attenuator 11 is made of a thin plastic or metal sheet of light shielding type, namely light shielding plate. It is formed so that its radius (d) may change gradually from the center of rotation 110. When it is rotated, the cross section of beam A of standard light passing the attenuator 11 changes continuously in a range from a maximum radius part 112a to a minimum radius part 112b. By rotating and positioning the attenuator 11 at a proper position, the cross section of beam A of standard light, namely the level of light quantity is controlled arbitrarily. Through a simple punching- out work or plastic molding work, the attenuator 11 can be produced easily without an exposure step at a low cost. There are no passing of standard light and no attenuation at the maximum and minimum radius parts 112a, 112b so that a wide dynamic range is attained.
