Abstract
PURPOSE:To make it possible to facilitate sighting and to perform highly accurate measurement by converging irradiated energy from an object to be measured by an objective lens, reflecting the energy by thin metal plate having a hole at its center, introducing it to an eyepiece, and inputting it to a sensor through a hole part at the same time. CONSTITUTION:The energy irradiated from the object to be measured is converged by the objective lens, reflected by the thin metal plate or metal film which has high reflectivity and the hole part at the central part, and introduced to the eyepiece. Thus the object is visually observed. The converged light is inputted to the sensor through said hole part, and an output signal is generated. For example, the irradiated energy from the object to be measured 1 is converged by the objective lens 2, reflected by the reflecting mirror 3 comprising the thin metal plate such as molybdenum or stainless steel, which has high reflectivity, thickness of 0.05mm., and a hole 31 at its central part. The sighting is performed by a mirror 4 and a lens 5, and the light through the hole 31 is measured by the sensor 7. Since the thickness of the reflecting mirror is small, the obstruction to the light path is small, and the highly accurately measurement can be performed.
