PURPOSE: A color lens graphic diameter measuring device, a method thereof, and a graphic diameter indicating method using the same are provided to simply measure a graphic diameter as a ruler and color lens images are projected on a screen when turning on a switch after receiving the color lens on a stage. CONSTITUTION: A color lens graphic diameter measuring device comprises a stage(10), magnifying glass(20), a light source(30), a projection lens(40), a reflecting mirror(50), and a screen(60). The stage includes a ruler on the bottom and a solution. The magnifying glass magnifies a look of a color lens lager than that when looking with the unaided eye. The light source irradiates lights to the color lens from the lower part of the magnifying glass. The projection lens projects images generated by the lights emitted from the light source and transmitted through the color lens on the upper part of the stage. The reflecting mirror reflects the images projected by the projection lens by turning a light path of the images. The screen projects the images reflected by the reflecting mirror. |
