  • Micro-distance lens detection device
    Patent number: 10627309
    Abstract: Provided is a micro-distance lens detection device adapted to detect a tested lens with a surface from a micro distance. The micro-distance lens detection device includes a light source module, a diffuser, a pattern test card, a collimator unit and an image pickup module which are arranged sequentially. The tested lens is disposed between the pattern test card and the collimator unit. The surface of the tested lens is separated from the light-emitting side of the pattern test card by the micro distance. The micro distance is less than 25 mm. Given the micro distance between the tested lens and the pattern test card, the optical resolution modulation transfer function (MTF) of the tested lens is correctly measured. Therefore, the lens detection device takes up little space.
