Disclosed is a photomask circuit detector, comprising a working platform (1), a transverse beam (2), an enlarging device (3) and a display device (4). An exposure region (5) for placing a photomask is arranged on the working platform (1). A light box (6) is arranged under the exposure region (5). Two oppositely disposed rails (7) are arranged on the working platform (1). The transverse beam (2) is slidably mounted on the two rails (7). The enlarging device (3) is slidably mounted on the transverse beam (2). The display device (4) is electrically connected to the enlarging device (3). The photomask circuit detector can move the enlarging device (3) to an optional position in the exposure region (5) according to the requirements for detection to enlarge the circuit on the photomask to be detected. The enlarged image is output by the display device. By utilizing the photomask circuit detector, detection personnel can increase detecting speed, which saves detecting time. Furthermore, the detected result is more accurate and detecting costs are reduced. There is no need to move the photomask during detection, which prevents material from being scratched or worn and will not damage the exposure region (5). |
