OSI Optoelectronics

As one of the largest manufacturers of standard and customer photodiodes and optical sensors in the United States, we leverage over 50 Years of success to deliver excellent manufacturing and engineering solutions from our facilities in the US, Malaysia and India.

In 2006, several subsidiaries were consolidated under the same brand name, OSI Optoelectronics, to enhance focus on the core business and utilize all resources within the companies to provide the best possible products. The new company serves the same customers and applications as its predecessors.

UDT Sensors

Founded in 1967, UDT Sensors is one the largest manufacturers of standard and custom photodiodes and optical sensors in the United States. The company provides design and manufacturing capabilities for both commercial and defense applications. Their products include standard and custom photodiodes optical sensors, thin/thick film ceramic hybrid modules, and more.


CentroVision was spun off from Centronics Ltd in the mid-’80s. It became one of the dominant players in the silicon photodiode industry, manufacturing UV, Visible, and Near IR detectors. OSI Systems, Inc. acquired the company in 2002.

OSI Fibercomm

OSI Fibercomm was established by OSI Systems Inc. in 1998. It offered innovative and leading-edge optical transmission solutions in the form of photo-detectors and subsystems for optical network applications related to high-speed data and voice transmission. The company was also a provider of custom fiber-optic subsystem designs and manufacturing services to a wide range of industry clients.


A/S Akers Electronics, the first microelectronic company in Scandinavia, was founded in 1967 to develop and produce microelectronics. AME A/S is one of the leading suppliers of high-quality, custom-designed, advanced microelectronics.

Laser Diode

The company was founded in 1967 as a premier manufacturer of solid-state lasers. LDI became the leader in laser diode technology and collaborated on many of the laser-based military programs still in use today. In 2000 LDI was purchased by TYCO Industries. The demand for high-energy, high-reliability lasers for telecommunications applications made LDI a synergistic acquisition which enhanced TYCO's dominance in the fiber optic space during this time. OSI Systems purchased LDI in 2011. OSI Systems’ vertical integration required a source manufacturer with vision, technology, and expertise, which would supplement its ability to become one of the premier Opto Assemblies companies in the world.

Advanced Photonix

In 2018, OSI Optoelectronics acquired Advanced Photonix from Luna Innovations. With more than 30 years of combined experience in photonics and optoelectronics, the pioneer in developing Large Area Avalanche Photodiodes (LAAPD) with world-class manufacturing globally, Advanced Photonix is one of the largest manufacturers of standard and custom photodiodes and optical sensors in the United States.
