Tilting Level Kits
 Brunson 545-190 Tilting Level Kit
This instrument combines precision with rugged reliability to execute the most demanding levelling jobs. This model telescope has adjustments to maintain the line of sight straight throughout a focusing range of two inches to infi nity, allowing the instrument to be located in the tightest of setups. This straightness is maintained at + 0.001 of an inch from two inches to 17 feet and one arcsecond from 17 feet to infinity. The main telescope tube has a removable section to facilitate conversion for auto-collimation, auto-projection, or installation of a right angle eyepiece. The optical micrometer produces repeatable readings with a resolution of 0.001 of an inch. (Finer micrometer resolution is available.) The horizontal axis pivots directly over the vertical axis, making the change in plane height less than 0.0001 of an inch for tilts up to 5 arc minutes either above or below horizontal. This important feature eliminates the need to perform the time-consuming precision plumbing procedure for leveling projects. This model has quality base components and leveling vials similar to the jig transits, allowing this instrument to sweep precise horizontal planes. Feather-touch controls are included for setting the coincidence vial.
