SupIR 35/110/450 mm 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)

Your Long Range Distance Needs Met

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.
