Embodiment Construction
[0014] Refer to attached picture. The present invention comprises a main objective lens 2, a diaphragm 3, a perforated reflector 12, an integrating mirror 11, a reflector 4, an image transfer mirror 5, a reticle 6, and an eyepiece 7. The light beam emitted from the measured object passes through the protective glass 1, Received by the main objective lens 2, the light beam is incident on the perforated mirror 12 through the diaphragm 3 that limits the beam aperture, and the small hole on the perforated mirror 12 determines the field of view of the measuring instrument, and a part of the light beam is incident through the small hole In the integrating mirror 11, when a part of the measured target beam passes through the small hole of the perforated mirror 12, the remaining part is reflected by the perforated mirror to the mirror 4, and is imaged on the reticle 6 through the transfer mirror 5 , the observer can see the measured target clearly through the eyepiece 7 . Therefore, ...
