Abstract

PURPOSE:To simplify both a detection and an operation, by installing a linear sensor which has a pattern composed of three straight lines with which the mask placed behind a lens to be inspected crosses at three points and detects a linear pattern at the detecting part. CONSTITUTION:The light emitting diodes 1 and 2 have different light emitting wavelengths are provided, and the light is sent through the collimator lenses 3 and 4 to the optical path divider 5 having the wavelength selecting performance. The beam having a specified wavelength amont the beams of diode 2 is transmitted toward the mirror 6 to be detected on the detecting surface 9 through the mask plate 8 and via the lens 7 to be inspected. For the purpose of this detection, the optical path divider 11 having the same wavelength selecting performance as the divider 5 is provided to the relay optical system 10. Thus the luminous flux sent from the diode 1 is reflected toward the optical path 12, and the luminous flux from the diode 2 is transmitted toward the optical path 13, respectively.
