WebDETERMINATION OF STADIA CONSTANT. For an instrument with an external focusing telescope, the stadia constant C is readily determined by setting up the instrument, focusing on any distant point at least 300 m away, and measuring precisely the distance between the reticule and the objective lens. This measured quantity is the focal length f. The telescope … WebIn internal focusing telescope brilliancy of image reduces due to extra internal lens. In modern telescope internal focusing telescope is used. When the anallatic lens is provided in the telescope of a tacheometer, the additive constant is zero. Generally, the deflection angle is measured twice, once with the telescope normal and once with the ... WebQuestion: The upper and lower stadia hair readings on a stadia rod held at station B were observed as 3.50 and 1.00 m, respectively, with the use of a transit with an internal focusing telescope and having a stadia interval factor of 99.5.
