Precision telescope optics mounted on a solid cast bronze
horizontal axle combine to produce a well-balanced
instrument with feather-touch controls. Patented ball
bearing mounts permit accurate sweeping of both
horizontal and vertical planes. Model 771-H employs the
194-TM Coincidence Level for precision leveling. The
194-TM has a 360-degree rotating turret to view the
bubble image from any position. A telescope-mounted
optical micrometer produces repeatable readings with a
resolution of 0.001 inch. (Finer micrometer resolution is
available.) |

 One of
Brunson Instrument Company's technological breakthroughs
was the development of the see-thru hollow horizontal
axis on the model 75-H. A partially coated, optically
flat mirror is mounted inside and rotates with the hollow
axis. This provides a right angle check of the
telescope's line of sight relative to the horizontal
axis. Additionally, the hollow axis allows you to view
the mirror from either side of the instrument to turn
optical right angles. The hollow axis gives you the power
to use several instruments on the same optical reference
line without disturbing their positions. |

| The model 75-H
possesses the remarkable ability to "prove"
each shot as it is made, removing any possibility of
error due to maladjustment from rough handling, extreme
temperature changes and other harsh environmental
conditions. Now optical technicians no longer need to
rely on the optical bench of some distant calibration
laboratory. They can verify the instrument's accuracy
themselves where it counts the most - ON THE JOB. 75-H Specifications Telescope:

 Like the Brunson model 75-H,
the model 76-RH was a totally new concept, again
utilizing the hollow horizontal axis. This time, a second
telescope, permanently focused at infinity, provides
self-proving sights at precise right angles to the main
scope. By simply shifting from one eyepiece to the other,
operators can establish or verify their position relative
to the basic references only one technician, where
previously two were required. The 76-RH is the undisputed
"workhorse" in optical alignment, providing
tremendous flexibility with substantial time and manpower
savings. |

 The synthesis of design and
function has enabled Brunson Instrument Company to
produce the ultimate optical tooling instrument: the
model 376-RHN. This distinct instrument incorporates a
focusable cross scope at precise right angles to the main
telescope. Originally desinged for non-gravity
applications, this instrument has become an indispensable
tool for alignment projects of all types... and with good
reason. This versatile instrument:
