Three Finest Models Satisfy All Levels of Requirements
Rapid, Stable, and Durable Compensator
20cm (7.9 in.) - Ultra-Short Focusing Range
The AT-B series can focus on objects at 20cm (7.9 in.) in front of
the telescope. This feature dramatically facilitates the works in
confined spaces.
2-Speed Focus (AT-B2)
Rotation speed of the focusing knob is automatically switched between coarse and fine, allowing for quick and precise focusing.
Clampless, Endless Fine Horizontal Adjustments
Fine horizontal knobs located on both sides of instrument can be
operated without clamping, speeding up aiming procedures to the staff
and other objects.
Easy-to-See Circular Level
Circular level can be viewed via integrated pentagonal prism (AT-B2)
or plane mirror (AT-B3/B4) without changing your eye height.
Horizontal Circle for Angle Measurement
Horizontal angles can be directly read in 1° or 1gon units. Free
rotation feature of the horizontal circle allows you to read any angle
from zero. The circle is covered for protection against dirt and
scratch. The readout window is located below the eyepiece for quick
reading.
All-Weather Dependability
With the IPx6 rating, the instrument is protected against powerful
water jets from all directions, meaning the AT-B series withstands a
sudden shower or torrential rainfall. The advanced protection design not
only prevents water penetration, but also deters clouding or
condensation inside the telescope.
Distance, Angle, and Height Measurement
In addition to height and angle, distance to the staff can be
simultaneously measured using stadia lines. This is accomplished by
reading the length of staff between two stadia lines and multiplying the
value by 100.
