Overview

New benchmark for cooled MWIR zoom optics for next-gen cooled MWIR 5μm SXGA detectors

The SupIR 10-135mm f/1.8 is a compact, high-performance MWIR zoom lens optimized for next-gen 1280×1024 SXGA cooled detectors with a 5µm pixel pitch. It delivers superior image clarity, long-range detection, and seamless integration, making it ideal for defense, security, aerospace, and industrial applications.

With 14× continuous zoom and detection beyond 17km for NATO vehicle targets, it ensures precision for surveillance, reconnaissance, UAVs, UGVs, RCWS, and industrial inspection. Its high MTF, athermalized optical design, and rugged coatings provide stability and durability in extreme conditions.

Designed for demanding applications, the lens features a wide field of view of 37.7° and a narrow field of view of 2.67°, with a compact 90mm front diameter, 129mm length, and lightweight 780g design. The SupIR 10-135mm f/1.8 sets a new standard in MWIR zoom optics, pushing the boundaries of thermal imaging with unmatched clarity, extended range, and reliability.

Key features:

Optimized for 1280x1024 resolution, 5μm pixel pitch MWIR cooled detectors
Detection range exceeding 17km, NATO vehicle detection
Continuous zoom lens with 14x zoom ratio
High Modulation Transfer Function (MTF) maximizing image clarity for long-range target detection and thermal contrast enhancement
High-durability coatings for abrasion, humidity, and thermal stability in extreme environments
Athermalized optical design maintaining consistent focus and image stability across wide temperature ranges

SupIR 10-135mm f/1.8 Motorized Cont. Zoom MWIR 5μm SXGA Imaging Lenses

DRI ranges enable one to easily estimate the maximum range that an object can be either detected, recognized or identified. It is important to note that these estimates are based solely on geometrical parameters – the target size, distance, lens focal length and camera detector pixel size. Signal level, detector sensitivity, atmospheric conditions and other factors are not considered!

The calculations used here are based on the “Johnson Criteria”. According to the Johnson Criteria, the minimum resolution, pixels on target, required to achieve a 50% probability for an observer to discriminate an object are:

Detection: An object is present – 2 pixels on target (Lower Bar)
Recognition: discern the type of object, a human vs. a vehicle – 8 pixels on target (Middle Bar)
Identification: discern specific objects, a man vs. a woman, a car model – 12.8 pixels on target (Upper Bar)
