A method for measuring the luminance of a light-emitting object having a surface which has a definite area and which emits a low-intensity light and a device therefore, wherein a light-receiving surface of an optical sensor is brought into direct contact with the surface of the light-emitting object to measure the luminance thereof. As the optical sensor, a semiconductor sensor panel or a solar panel is preferably used. The luminance of a light-emitting object which emits a low-intensity light can be measured simply, easily and properly without a darkroom and without a means such as a light condensing lens system which is complicated and difficult to use. |
