Introducing the WNDSN High-Viz Quadrant Telemeter

BERLIN, 2020-01-23 - WNDSN Messtechnik is introducing the latest iteration of one of the most popular WNDSN Telemeter products. After more than a thousand units sold, the new white WNDSN Quadrant Telemeter is released in the beginning of 2020 in a high-contrast, high-visibility version with a number of new features.

"I don't paint things. I only paint the difference between things." --Henri Matisse

The WNDSN Quadrant Telemeter is a measurement and calculation instrument for indoor and outdoor use, its users require attributes such as ruggedness, durability, and integrity of the various scales. For black and transparent instruments, WNDSN uses cast Acrylic that works reliably under these conditions and is deep-engraved.

To increase legibility without losing durability in the process, after various tests examining legibility, resilience, and resistance of different surfaces, a new material has been chosen: A sandwich acrylic consisting of a black core with matte white outer surfaces that are cut through by engraving, thereby exposing the black material underneath for high contrast and scales that cannot wear off (a requirement that prohibits simply printing the scales).

Other new and updated features on the WNDSN High-Viz Quadrant Telemeter are:

  • A 100 MIL mark on the angular size scale, it's a special value for various calculations, one of which being the point where an object of unknown size has a height of 0.1x the known distance, or vice versa.
  • Another scale mark, just as easy to miss; this one is also to be found on the angular size scale and is located at 7.5°. WNDSN’s naked-eye astronomy users have asked for this one, 7.5° equals 30 minutes of earth rotation and the mark can be used against a fixed star to measure minutes passed in the sky.
  • The slope/tan scale on the quadrant side received a makeover and got redesigned according to the updated WNDSN style guide for logarithmic scales. The result is a more refined scale with higher precision and better readability.

WNDSN Telemeters are wallet-size distance and altitude nomographs developed in the WNDSN applied science lab. They combine a thousand years of civil engineering, surveying, navigation, and astronomy in durable, low-tech, high utility instruments that can be brought anywhere, are self-containing, and independent of external, modern technologies.

The WNDSN Quadrant Telemeter is a naked-eye observation instrument for measuring angles via various inputs and sighting methods. In addition, the Quadrant Telemeter is a graphical, analog computer providing functions to directly process or convert the acquired values.

Scales on the WNDSN Quadrant Telemeter:

  • Angular size and distance
  • Height or depth of object
  • Altitude or elevation
  • Computation of sine, cosine, and tangent from a given angle and back
  • Degree and slope quadrant
  • Shadow square
  • Inclinometer

The various engraved scales enable the user to copy dimensions from the real world onto a small ruler in their hand, and read the matching distances directly from the instrument, thereby computing arbitrary navigational distances and other essential information about the world around us, as long as a triangle is formed between user, scales, and object of interest.

Under certain conditions or in cases where laser rangefinders tend to fail or result in errors, WNDSN Telemeters prevail and can be used as primary or “second opinion” tools, to cross-check values obtained with different means, or in austere situations when other methods fail or are unavailable.

The credit-card sized instrument is handmade in Germany and manufactured in the spirit of astronomical instruments of the Renaissance, built by the likes of Tycho Brahe, Johannes Kepler, Galileo Galilei, and Gemma Frisius. The scales are laser-engraved and precision-cut into 3 mm black, acrylic with white, matte surfaces. The device carries the WNDSN maker's marks; scientific instructions are engraved and supplemented by a printed how-to in both English and German. A 240-page printed manual is included as a PDF and is also available separately at WNDSN or via bookstores.

About WNDSN

WNDSN's Applied Science Lab, based in Berlin, develops and manufactures that which can't be improvised; measurement, navigation, and surveying instruments informed by the motto "Ex Mensura, Scientia" -- knowledge from measurement.

WNDSN produces archival quality products that are designed with intent by combining techniques proven over centuries; arcane science meets cutting edge contemporary methods, resulting in iconic, timeless, high-utility designs.

In addition to custom-built instruments and tools, metrology & illumination solutions, WNDSN creates expedition mementos and morale patches to celebrate cross-disciplinary exploration in the spirit of the Renaissance. WNDSN morale patches are acutely designed -- no line is left to randomness, no element is mere filler. They serve as infographics, how-tos for the WNDSN tools, magic sigils, as well as functional markers.
