Telescope Length 310 mm, Height 670 mm (height of theodolite + gyroscope

The instrument pictured above is typically used by the military. Their principal application is in mining, tunnelling and gunnery, but in conventional surface surveys they can be used to provide initial orientation, in place of magnetic bearings or astronomical azimuths.
The instrument shown at the top is referred to as a 'gyro-theodolite'. It basically consists of a gyroscope attached to the bottom of a Hilger & Watts micrometer theodolite. The gyroscope enables the direction of true north to be determined with a standard error of about ±15" within a very short time. The instrument shown on the bottom is a 'meridian indicator' (also known as a Precision Indicator of the Meridian) which is connected to the gyroscope and includes external connection to the power supply. It is basically a meter graduated directly in angular units, and the reading is thus a maximum when the gyro is pointing north and a minimum when it is pointing east or west.
The theodolite remains permanently attached to the gyro assembly. The gyroscope unit is suspended in vertical gimbals, which lie in the line defined by the downward extension of the (permanently) attached theodolite. The actual gyroscope is floated on a film of liquid, and it is called a floating gyroscope to distinguish it from the pendulous type in which the gyroscope unit is suspended and hangs under gravity.

Manufactured in 1966 (approx). Catalogued in 1997

Telescope length 135mm, Height 284mm


Description

The Optical Micrometer Theodolite Theo 010 is suited for all geodetic work and the principal application of the instrument is for triangulations of 2nd to 4th order, precision traversing above and below ground and field astronomical observations.
The instrument is compact and completely self-contained and all it's mechanical and optical elements are conveniently arranged.
The theodolite consists essentially of a fixed base with a rotatable horizontal circle (84 mm diameter) and an upper part, or alidade, which is rotatable on a steel cylindrical spindle and carries the tilting trunnion axis with the vertical circle (60 mm diameter) and telescope, the circle reading microscope and the built-in optical plummet. The centre spindle of the instrument fits into a socket in the tribrach and is secured by the clamp screw (DIN centring system). The tribrach carries the levelling foot screws and is connected to the tripod head through the base plate and the spring plate by the attachment screw. The mirror objective telescope of intrinsic shortness and 31x magnification has internal focusing and is completely dustproof. The effective diameter of the objective lens is 53 mm and the telescopes shortest sighting distance is 2 metres.
The manipulating knobs and clamping levers are so situated that they can be easily operated from either telescope position, and the screw threads are completely enclosed and protected. Built-in to the base of the instrument is an optical plummet with which, sighting through the hollow spindle it is possible to achieve a high degree of centering over ground points.
The horizontal and vertical scale intervals of the micrometer is 1". The altitude bubble sensitivity is 20"/2mm. The circles have double line graduations, the actual division being between the two lines. By turning the micrometer head, the circles apparently move in opposite directions until the upper and lower double lines are made to coincide. The shifting of the images, in minutes and seconds, is shown in a small window on the right hand side of the microscope field. The scale divisions of both the horizontal and vertical circles are in intervals of 20 minutes.

Weight of instrument is 5.3 kg
There is only one mirror used for both the horizontal and vertical circle illumination

Model : T16

Telescope length 150 mm, Height 255 mm

This is the Wild T16 (E) optical scale-reading theodolite. Instead of a micrometer, it features a scale microscope where the images of the vertical circle and the horizontal circle are seen in the field of view at the same time. The theodolite is ideal for triangulation, traversing, cadastral surveys, setting-out and alignment surveys, determining control points and trigonometric heighting.
The instrument incorporates a detachable tribrach which is designed for fast, accurate interchange of the theodolite against a reflector, target, optical plummet, etc. A central-pivot locking mechanism engages the three studs of the centring flange without lateral pressure and holds the instrument firmly in the tribrach dish. An optical plummet is included on the alidade of the theodolite.
The graduation interval of the horizontal and vertical circles is 1 degree, the optical scale interval is 1 minute (1') and estimation can be made to 6". The reading microscope is parallel to the telescope and both circles are easy to read, whatever the telescope position. To prevent mistakes, the horizontal circle is a brilliant yellow, and a large scale mirror in the telescope standard ensures bright circle illumination. The magnification of the telescope is 28x, the diameter of the objective lens of the telescope is 40 mm, and the shortest pointing distance is approximately 1.5 metres. The telescope provides an 'inverted' image. The bubble sensitivity of the plate level is 30" per 2 mm run.
Furthermore, the T16 is supplied in a watertight, dustproof metal case with a carrying strap, and the steel hood protects the instrument from jolts and knocks.

Weight of instrument and container is 4.7 kg and 2.0 kg respectively.

Model : DKM2-AEM

Telescope length 175 mm, Height 225 mm

This Kern DKM2-AEM is a one-second (1") optical micrometer theodolite of high precision suitable for triangulation, traversing, deformation measurements, precise layout work in building construction and sub-surface work, astronomical observations, optical tooling and photogrammetric control.
It incorporates a trunnion axis micrometer which serves the same purposes as a striding level (also included in the collection), and is used to increase the accuracy and reliability of the horizontal directions at steep sights. The trunnion axis micrometer permits to measure the inclination component of the standards in the direction of the trunnion axis. From these measurements the inclination of the trunnion axis and the correction of the horizontal direction can be computed. The practical measuring range of the trunnion axis micrometer is approximately ±30" and the inclination of the trunnion axis can be determined to ±1".
The magnification of the telescope is 32x, the diameter of the objective lens of the telescope is 45 mm, and the shortest pointing distance is approximately 1.7 metres. Other features include maintenance-free vertical circle liquid compensator (working accuracy of 0.3" and range of 2'), upright telescope image, digitised circle reading, optical plummet with adjustable focus, two-speed (course and fine) azimuth and elevation tangent screws, cam controlled short-stroke levelling system and course-fine circle orienting drive.
The accuracy of the instrument is excellent since the scale interval of the micrometer is 1" and estimation can be made to 0.2". The diameters of the horizontal and vertical circles are 75 mm and 69 mm respectively, and one mirror caters for the illumination of both circles. The sensitivity of the plate level is 22" per 2 mm.
The instrument requires special 'Kern' centring tripods and is not compatible with any other brands. Centring with the tripod produces an accuracy of 0.5-1mm. The theodolite is provided with a metal carrying case, and the tool compartment in the base of the carrying case contains a hexagonal wrench with screwdriver, one adjusting pin and two Allen wrenches (1.5 mm) for the adjustment of the collimation error.

The instrument can be combined with the Kern DM 501 Electronic Distance Meter (also included in the collection)
Weight of instrument and container is 6.2 kg and 2.4 kg respectively.
