The Benoy dial was invented by Walter Gordon Benoy of [[Collingham, Nottinghamshire]], England. Whereas a gnomon casts a sheet of shadow, his invention creates an equivalent sheet of light by allowing the Sun's rays through a thin slit, reflecting them from a long, slim mirror (usually half-cylindrical), or focusing them through a [[cylindrical lens]]. Examples of Benoy dials can be found in the United Kingdom at:<ref name="BSSRegister">List correct as of British Sundial Register 2000. {{cite web |title=The Sundial Register |url=http://www.sundialsoc.org.uk/register.htm |url-status=dead |archive-url=https://web.archive.org/web/20070717073638/http://www.sundialsoc.org.uk/register.htm |archive-date=2007-07-17 |access-date=2008-01-05 |website=British Sundial Society}}</ref>
