The Ella Series offers advanced MWIR continuous zoom performance for 640 × 512 × 15 µm cooled detectors, covering focal lengths from 25–500 mm F/5.5 up to 70–1400 mm F/5.5 with optional beam extenders. Combining a high optical zoom ratio with active athermalization, Ella lenses maintain precise focus from wide to narrow fields of view and through changing environmental conditions. With motorized dual-axis control, excellent boresight stability, and fast zoom/focus response, the series delivers long-range imaging accuracy and clarity. Built for field endurance with IP66/67 sealing and robust mechanical construction, Ella lenses are ideally suited for defense, surveillance, and security systems requiring extended MWIR reach and exceptional thermal imaging fidelity.
