MWIR Zoom Lens Assemblies
Teledyne FLIR custom and off-the-shelf mid-wave infrared (MWIR) 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 MWIR 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.
- Optimized for smaller pixel, larger-format focal plane arrays (FPA)
- Elimination of expanders minimizes lens count, maximizes transmission, reduces size & weight, and improves MTF
- Proprietary alignment method improves performance, boresight retention, and reliability through zoom
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.
- Compensate for range and thermal gradient
- Includes built-in-test (BIT), data logging module, ID module and other features
- High speed communication at 1 kHz
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.
- Provide the ideal interface to your camera to match cold shield height
- Accommodate operational environment or custom enclosure
- Collaborate and support to make the mission a success
