The F5.5 Continuous Zoom Motorized Thermal Objective is designed for cooled thermal imaging systems operating in the 3–5 μm spectral band. Its F/5.5 optical design, continuous optical zoom capability and multilayer broadband coatings provide high infrared transmission and clear thermal imagery.

With a compact, shock-resistant structure suited to electro-optical system integration, this MWIR thermal lens delivers reliable performance for border security, coast guard missions and long-range reconnaissance. Continuous zoom between a wide field of view of 22.5° and a narrow field of view of 2° enables seamless transitions from wide-area observation to detailed long-range surveillance, supporting situational awareness.
