Aldis Brothers was a maker of lenses and other photographic equipment, in the Sparkhill area of Birmingham, England, from 1901, when H.L Aldis left the Dallmeyer company. Among their most successful products was the Uno Anastigmat, which comprises three glass elements, like the Cooke anastigmat, but two of which are cemented.

Aldis produced lenses for some Ensign cameras, some of which are identified with the brand Aldis-Ensign or Aldis-Butcher.

During both the First and Second World Wars, the company made military equipment. Its name is particularly strongly associated with the Aldis lamp, a signalling lamp used to send Morse Code.

The company was bought by the Rank organisation some time after the Second World War, and concentrated on slide projectors, episcopes etc.
