Teledyne FLIR custom and off-the-shelf long-wave infrared (LWIR) continuous zoom (CZ) optical assemblies and lenses are for integrators and operators who do not compromise on quality. All lens assemblies have near diffraction limited performance and include advanced features that ensure continuous focus through the zoom. Formerly New England Optical Systems (NEOS) and now part of Teledyne FLIR, the world-class technical services team provides product support and can also develop new or customize existing lens assemblies for a camera, application, and mission. Designed to maximize infrared-camera performance, the LWIR CZ lens assemblies provide the competitive advantages required in the field and marketspace for a wide range of defense, security, and commercial applications.

  • Uncompromised Performance and Reliability

    Designs have near diffraction limited performance through zoom enabling users to Detect, Recognize, and Identify (DRI) threats in real time.

  • Smart Optics Ensure Continuous Focus

    Control electronics and additional features go beyond simple focus and zoom to provide focus when and where you need it.

  • Custom Designs and Support for the Mission

    Teledyne FLIR technical services team can develop new or customize existing zoom lens assemblies for a camera, application, and mission.
