Our history

1977: The Birth of SigmaKoki

SigmaKoki Co., Ltd. was created in Tokyo, Japan in 1977. The goal was to provide an industrial and manufacturing solution of optical components to researchers at the University of Tokyo. Fast forward 40+ years and SigmaKoki is the most recognizable name in Japan for manufacturing precision Optics, Optical Systems and Opto-Mechanics. The company owns and operates four production facilities. Three in Japan, (All ISO 9001 and 14001 Certified) and 1 in Shanghai, China. Our identity revolves around our customers. We provide support to leading researchers that require knife edge manufacturing technology, in addition to a wide variety of industries for Original Equipment Manufacturers. We have always been focused on providing the highest service and quality of products. Thanks to the “Monozukuri” mindset, SigmaKoki is a key player in the global market for manufacturing and supplying high precision Photonics Components and systems.

1995: OptoSigma Corporation

SigmaKoki’s first expansion outside of the Asian market was in 1995 when OptoSigma Corporation was created in Santa Ana, California. The goal was to enable stateside manufacturing, technical and Sales support to customers throughout the Americas. Our Southern California facility is 18,500 square feet and incorporates class 1,000 clean rooms and class 100 working environments. We design and manufacture Optical Coatings and have upwards of 100 standard coating designs, along with the ability to design and manufacture the most demanding custom films, all under one roof. Additionally, we manufacture Opto-Mechanical Assemblies for a variety of industries and applications. Furthermore, we maintain a significant level of standard catalog inventory to enable next day delivery for stock items. Our sales and engineering staff are standing by to support your most demanding requirements.

2014: OptoSigma Europe

OptoSigma pursued its expansion into Europe by setting foot in Paris, France. Our desire was to expand the promotion of the OptoSigma brand to the European market. We provide sales and technical support to research and industrial based customers. Our sales and engineering staff are all experienced in photonics to support a large variety of industries and applications. OptoSigma Europe continues to grow and will also be expanding to add manufacturing in the near future. This closer support allows us to stock the popular items for fast shipping to our European customers

2017: E-Commerce Website

Following the globalization trend and understanding a need from the market to have easier access to information, OptoSigma launched its e-commerce website in 2017, enabling global online purchasing of our products and services. Our goal is to provide the highest online experience by making sure our site is intuitive, fast, and complete with all of the information you need to make the right decision. With that in mind, we also know that choosing the right products may not always occur. This is why we have a no questions asked 30-day return policy for most standard products.
