Pentax is a world-famous optical brand, and its products cover astronomical telescopes, medical endoscopes and glasses. Pentax's brand culture can be traced back to Asahi Optical Joint Venture established in Tokyo, Japan in 19 19.
Asahi Optical Co., Ltd. is a famous optical manufacturer in Japan, which has created a number of world firsts and Japanese firsts in photography. As a brand of SLR cameras under Xu Optics, Pentax once dominated, and once existed as a world-famous Pentax Company (in 2002, Xu Optics was officially renamed Pentax Company). In 2007, all the business of Pentax was absorbed and merged by HOYA Co., Ltd., another major Japanese optical company, and Pentax no longer existed as an independent company. 20 1 1, Ricoh Group, a famous Japanese office equipment manufacturer, announced the acquisition of the photography department of HOYA Co., Ltd., and the Pentax brand was split into two parts, except the medical optics part, which still belongs to HOYA Co., Ltd., and its main imaging business was renamed from 20 1 1(20 13).
