71-1010

Designed to produce the highest, accuracy in optical tooling and align- ment work. Azimuth center is hollow and the line of sight is centered with this axis so that ii is possible to sight verticaly down through the in base. The instrument will establish precise vertical planes and plumb lines. When equipped with a right angle eyepiece, zenith sights or upward plumb lines can be established, two speed tangent screws on both the azimuth and elevation axles ease leveling and auto collimation, the instr- ument comes equipped with a standard level vial no. 71-3260 attached to the telescope and a circular vial on the plate, the telescope focuses from 8 in. To infinity, magnification varies automatically from 20x at 8 in. To 30x at infinity, resolving power is 4 seconds of arc, weight of instrument approx 26.5 lbs. Telescope is 11.25 in. Lg with fully erecting achromatic k/e optical systems, field of view is 55 min. At infinity, 6.4 mm at near distance, effective aperture is 30 mm, height 10.7
