Build-To-Spec (BTS) & Build-to-print (BTP) expertise

With decades of knowledge and experience, having designed and delivered thousands of infrared components in the LWIR, MWIR or SWIR wavebands for multiple defense applications, Ophir has earned its reputation as a world-leading, one-stop-shop designer and manufacturer of Infrared thermal imaging components for defense OEMs.
Advanced optical design technologies and innovative engineering are applied to our build-to-specification (BTS) development processes, allowing us to reach efficient design results with fewer elements, lighter components, and reduced-cost.
These same advanced capabilities and expertise are combined with cutting-edge manufacturing technologies such as MRF technology, diamond-turning machines, CNC generators and polishers, automated coating chambers, and advanced metrology and test equipment, to create our our build-to- print (BTP) component and assemblies, including aspheric, diffractive and spherical lenses, mirrors, domes, windows and prisms.

Widest IR assemblies product range

Our range of long-lasting products includes IR complex lens assemblies with various focus mechanisms:

  • Fixed
  • Manual
  • Motorized focus
  • Continuous zoom

From LWIR, MWIR to SWIR we excel in the production of the following product configurations:

  • Single Field-of-view (1-FOV)
  • Multiple FOV
  • Motorized Continuous Zoom

Our knowledge and experience in motorized continuous zoom lens systems is recognized by customers around the world.

Meeting defense market strict demands

We harness innovative designs to provide largest portfolio products with field-proven performance, answering the strict demands of global defense customers for:
