Abstract

To provide a lens-measuring device capable of fully reducing the light quantity uneveness of the light incident on a chart. Light is allowed to be incident on an integrating sphere 24 from a light source part 63 and is diffused, and the diffused light is allowed to be incident on the chart 23 to form a light figure, and the light figure is allowed to be incident on a lens 1 and the light figure imaged by the lens 1 is imaged by a camera 26, and MTF of the lens 1 is measured, based on an image imaged by the camera 26. By using the integrating sphere 24 as a diffusion means of the light incident on the chart 23, a light having less light quantity uneveness is allowed to be incident on the chart to measure the MTF, and measurement accuracy can be improved.
