etalon

e·ta·lon

(ā′tə-lŏn′, ĕt′ə-)

A type of interferometer in which incoming light is repeatedly refracted and reflected between two surfaces into multiple beams that are then focused together, causing self-interference of the light.

[French étalon, standard (of weight or a unit of measurement), reference point, etalon (in reference to the fixed widths between the two surfaces in the first such interferometers), from Old French estalon, standard, of Germanic origin; akin to Middle Dutch stael, model, sample.]
