ABSTRACT:
An optical measuring system has a first optical measuring instrument and a second optical measuring instrument. The optical measuring system includes a first optical path to guide a first beam from a measuring region to the first optical measuring instrument, a second optical path to guide a second beam from the measuring region to the second optical measuring instrument, an optical system through which the first and second optical paths extend and in which the first and second optical paths are paraxial, a reflection area to change the direction of the first optical path, the second optical path crossing the reflection area, and a light transmission area arranged at a position where the reflection area and second optical path cross each other, the light transmission area having a higher light transmittance than the reflection area.
