Bernsteintype

The Bernsteintype, also known as the Berntsen type, is a type of latitude ring, which is a section of graduated circle, typically made of brass or other metals, that is used for measuring angles and positions in surveying and geodetic applications. The name "Bernsteintype" likely originated from its manufacturer or designer, who was possibly named Bernstiern or Berntsen.

This particular type of latitude ring features a series of radial divisions, often with two sets of graduations: one in degrees and minutes and another in seconds. The graduations are usually marked with a fine line, indicating the degree of angular resolution. The ring is mounted on a central axis, which facilitates easy rotation and precise positioning.

The Bernsteintype typically includes various adjustment screws and micrometer screws for adjusting the angle settings, allowing users to obtain highly accurate measurements. This instrument's key features include its fine graduations, precision machining, and robust mechanical construction.

The Bernsteintype has been widely used in the fields of surveying, geodesy, and photogrammetry for angular measurements, typically in conjunction with a theodolite or a transitscope. Due to its precision and durability, this latitude ring remains a sought-after in many parts of the world, particularly by professionals working in the fields mentioned above.

It is worth noting that the name "Berntsen" may also refer to a manufacturer, and it's unclear if there's any direct connection between the type of instrument and its manufacturer. Nonetheless, it has contributed to accurate measurements in the given fields, and its influence is still seen in modern surveying and geodetic equipment.
