The F4 Continuous Zoom Motorized Thermal Objective is designed for cooled thermal imaging systems operating in the 3–5 μm spectral band. Its F/4 optical design, continuous optical zoom capability and multilayer coatings provide high infrared transmission and clear thermal imagery.

Designed for electro-optical system integration, this MWIR thermal lens supports border surveillance, coast guard missions and long-range reconnaissance. Its rugged construction delivers reliable performance in harsh environments, while continuous zoom enables seamless transitions from wide-area observation to detailed long-range surveillance, enhancing situational awareness.
