The Y level or wye level is the oldest and bulkiest of the older style optical instruments. A low-powered telescope is placed in a pair of clamp mounts, and the instrument then leveled using a spirit level, which is mounted parallel to the main telescope. The term dumpy level (also builder's level) endures despite the evolution in design. They ...

Wye level, an early optical level; Wye (rail), a term used in North American railroading equivalent to an English railway triangle; Wye fitting, used in piping and plumbing; Wye connection, used in three-phase electrical circuits; Wye interchange, or directional T interchange between two or more roads or highways
The level must be horizontal to get a valid measurement. Because of this, if the horizontal crosshair of the instrument is lower than the base of the rod, the surveyor will not be able to sight the rod and get a reading. The rod can usually be raised up to 25 feet high, allowing the level to be set much higher than the base of the rod.
Combining a spirit level with an optical telescope results in a tilting level or dumpy level. [5] These leveling instruments as used in surveying to measure height differences over larger distances. A surveyor's leveling instrument has a spirit level mounted on a telescope (perhaps 30 power) with cross-hairs, itself mounted on a tripod. The ...
The initial setting operation includes fixing the theodolite on a tripod, along with approximate levelling and centering over the station mark.For setting up the instrument, the tripod is placed over the station with its legs widely spread so that the centre of the tripod head lies above the station point and its head approximately level (by eye estimation).
It was founded on 20 February 1948 when Adam Hilger, Ltd, founded in 1874, merged with Messrs E. R. Watts and Son by Edwin Richard Watts (1833–1901) [1] and George William Watts (c. 1871–1954), [2] founded in 1865. [3]
The Corrective Optics Space Telescope Axial Replacement (COSTAR) is an optical correction instrument designed and built by NASA. It was created to correct the spherical aberration of the Hubble Space Telescope ' s primary mirror , which incorrectly focused light upon the Faint Object Camera (FOC), Faint Object Spectrograph (FOS), and Goddard ...
