The partnership of Lejeune and Perken was founded in 1852 by T. Lejeune and Louis Edmond Perken. The firm was dissolved at the end of 1873: it was described in the dissolution notice as an importer of optical instruments, with the address 24 Hatton Garden, London; however, Lejeune and Perken seem to have made some equipment. The business was continued in partnership with Arthur Rayment as Perken, Son and Rayment (Channing & Dunn give the date of this company as 1887, a few years after Lejeune and Perken separated. The London Gazette carried a notice stating that this partnership, described as manufacturers and importers of optical and scientific instruments, was dissolved by mutual consent at the end of 1889. However, this seems to have been a formality, marking the transfer of the company to a new generation in the Perken family. The partnership reported as dissolved was that of Louis Edmond Perken and Frederic Louis Perken with Arthur Rayment. The London Gazette carried another notice, reporting the dissolution of Perken Son and Rayment 'by effluxion of time' (that is, the partnership agreement had run its stated course) at the end of 1899. The partnership dissolved this time was that of Frederic Louis Perken, Edgar Theodore Perken and Arthur Rayment. The business was continued as Perken, Son and Company, still at 99 Hatton Garden. This company held a patent relating to thermometers; patents were filed in the 1950s by the company Heath, Hicks and Perken (thermometers) Ltd. of Eltham; it seems likely that Hicks was the company of James J. Hicks, also originally of Hatton Garden. Heath, Hicks and Perken appears to have been wound up in 1979.
Louis Edmond Perken died in 1907.
Originally just an importer, the company became a maker of cameras, lenses and other photographic equipment, including studio and darkroom apparatus. The company also made magic lanterns and accessories, telescopes, binoculars, surveying and other scientific equipment.
The company used the brand name Optimus for a great many of its products, including cameras, lenses and magic lanterns.
All the lenses were sold with the Optimus brand
