SupIR 45-900 mm f/4.0 Motorized Continuous Zoom MWIR SXGA Imaging Lenses
SupIR 45-900 mm f/4.0 Motorized Continuous Zoom MWIR SXGA Imaging Lenses
The SupIR 45-900mm f/4.0 is based on the legacy of the SupIR 15-300mm f/4.0 with its proven track-record of thousands of units operating in the field and its ruggedized design. This motorized focus MWIR imaging zoom lens has a 45 to 900 mm focal length with an f-number of 4.0. This continuous zoom lens is designed for 1280x1024 SXGA format cooled MWIR cameras and provides superior DRI ranges exceeding 26km for vehicle detection, ideal for long range observations and surveillance systems.
- Advanced technologies for the highest performance mid-wave focal planes
- High-durability and low reflection hard-carbon 3.4-5 µm MWIR AR coatings
- Passive athermalization with the highest imaging performance from -32 to +75°C
- Optimized for 1280x1024 SXGA cooled MWIR cameras with 10 μm pixel pitch
- Focus and f# maintained for crisp image through the entire zoom range
- Designed for long range observation systems with vehicle detection exceeding 26 km See All Features

Features
SupIR 45-900mm f/4.0 Detection, Recognition & Identification (DRI) Range
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)
High Performance Mid-Wave Focal Plane
Using advanced technologies, top-quality materials and unique coating techniques, together with innovative engineering and opto-mechanical designs, we have earned a reputation for excellent performance, durability and quality.
High-durability and Hard-carbon AR Coatings
Our highly abrasion-resistant, anti-reflective advanced optical coatings include several types of Hard Carbon coatings which provide maximum durability, energy transmission & minimal reflection. Our innovative coating technologies include:
- Physical Vapor Deposition (PVD) – Thermal heating and electron gun
- Ion Assisted Deposition (IAD) – Ion gun
- Plasma Enhanced Chemical Vapor Deposition (PECVD) for DLC coatings
Passive Athermalized Lens Assembly
Our IR imaging lens assemblies incorporate passive athermalization of the lenses and opto-mechanical system to maintain the highest imaging performance over the full operating temperature range. We use advanced materials that enable unique athermalization properties and optomechanical designs that effectively compensate for optical variations over a wide temperature range.
