Goniometer 测角仪

（重定向自Contact goniometer）
Goniometer made by Develey le Jeune in Lausanne, late 18th–early 19th century
Manual (1), and Mitscherlich's optical (2) goniometers for use in crystallography, c. 1900
Surface scientists use a contact angle goniometer to measure contact angle, surface energy and surface tension.
Surface tension exists because the molecules inside a liquid experience roughly equal cohesive forces in all directions, but molecules at the surface experience larger attractive forces toward the liquid than toward gas

A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry is derived from two Greek words, gōnia, meaning angle, and metron, meaning measure.

The first description of a goniometer, derived from the Astrolabe, was apparently in 1538, by Gemma Frisius.
