摘要： An electronic distance meter includes a sighting telescope optical system having an objective lens for sighting an object, and an optical distance meter which includes a light-transmitting optical system for transmitting a measuring light toward the object via the objective lens, and a light-receiving optical system for receiving a portion of the measuring light which is reflected by the object. The light-transmitting optical system includes a light-shield mask having a translucent portion to define a beam profile of the measuring light. The translucent portion comprises a filter having an uneven density, light transmittance of a central portion of the filter being greater than light transmittance of a peripheral portion of the filter.

摘要： A surveying instrument includes a sighting telescope having an objective lens and an eyepiece; a Porro-prism erecting system; a semitransparent surface formed on a reflection surface of the Porro-prism erecting system; a beam splitting prism adhered to the semitransparent surface; and a focus detecting device which detects a focus state from a correlation between a pair of images respectively formed by two light bundles which are respectively passed through two different pupil areas of the objective lens and passed through two separate areas on the semitransparent surface. An area of a surface of the beam splitting prism which is adhered to the semitransparent surface is smaller than an effective area of the reflection surface of the Porro-prism erecting system. The semitransparent surface and the beam splitting prism are positioned so that the two light bundles are incident on the semitransparent surface at the same incident angle.
