Production Capabilities

Ophir designs and manufactures a wide range of high-performance MWIR and LWIR optical elements and lens assemblies for use in cooled and uncooled cameras. We deliver OEM Build to Spec (BTS), Build to Print (BTP) and Commercial Off-the-Shelf (COTS) products, which include single FOV, multiple FOV and motorized zoom lenses, as well as IR components.
With decades of field-proven experience, and a dedicated team of engineering experts, there’s no task too big or too small for us. We manufacture every optical component to the highest standard, using the best quality materials. Our high-end, large production facilities enable us to work with the tightest tolerances and produce the widest variety of components, from VIS to LWIR wavelengths, for any application. Our R&D engineers design, develop, and test lens assemblies, leveraging state-of-the-art design tools and continuously improving manufacturing techniques. Our innovative optomechanical designs use fewer elements and lighter-weight components to increase efficiency and lower assembly costs.
