Steiner officially announces that it has acquired two U.S. companies, the Sensor Systems Division of The O’Gara Group. The group is comprised of Sensor Technology Systems (STS) and Diffraction LTD.

For more than 25 years, STS and Diffraction have provided the most technologically advanced night vision, beacon and laser devices. Specialized users include Homeland Security, special operations forces, law enforcement and other military personnel.

“Whether it’s digital imaging systems like night vision or thermal rifle scopes, or high-end military technology adapted for the commercial user, it’s inevitable that the future of optics is electronic,” said Stephen McKelvain, Steiner’s Chief Global Marketing Officer. “By combining STS and Diffraction with our established eOptics Division and our existing line of daylight optics, Steiner solidifies its pioneer role in electro-optics.”

STS is best known for its Low-Profile Night Vision Goggle, the AN/PVS-21 used by special operations forces around the world. STS designs and manufactures equipment, all of which provides improved situational awareness in both day and night operations. STS specializes in supporting the equipment needs of government, military and law enforcement worldwide featuring:

  • Intensified night vision systems
  • Heads Up Display (HUD) and Helmet Mounted Display (HMD) systems
  • Combat ID/IFF systems

Diffraction LTD is an innovator in optical, electrical and mechanical systems, providing the military with some of the most advanced, electro-optic devices in the world. Key focus areas include:

  • Digital and fused imaging systems
  • Optical beacons for combat ID or tagging, tracking and locating
  • Lasers including illuminators and pointers

Diffraction’s primary focus has been on advanced electro-optic imaging and communication designs throughout the optical spectrum including UV, Visible, NIR, SWIR, MWIR and LWIR.

Steiner delivers trusted sighting solutions to the world by building cutting edge optics and eOptics products that offer the performance demanded by military/law enforcement and commercial markets globally. Steiner’s superior performance, service and support will enable our users to more quickly and accurately detect, identify, and target their objectives.

The STS and Diffraction products are built in the U.S., and will join Steiner’s current line of eOptics products, which are also American made, and manufactured in Monterey, California.
