Wndsn Telemeter Toolmaking

Engravings, accuracy, and precision.

Wndsn Telemeters are handmade and manufactured in the spirit of astronomical instruments of the age of discovery, built by the likes of Tycho Brahe, Johannes Kepler, Galileo Galilei, and Gemma Frisius.

Accuracy vs. Precision

Accuracy is determined and limited by the precision with which physical markings can be created and reproduced, as well as read and aligned to the corresponding object to be measured.

The maximum achievable precision is ± half of the smallest division of the scales.
