SupIR 33.5 mm f/1.3 Detection, Recognition & Identification (DRI) Range
Assumptions: 50mK NETD for LWIR uncooled detectors 12µm pitch | 30Hz frame rate | 50% detection probability | 0.2km-1 atmospheric attenuation coefficient | human ΔT = 1.74x0.46m, 5°C | vehicle ΔT = 2.3x2.3m, 2°C | Fill factor – 80% | Center Wavelength – 10µm | Q factor – 1.121
DRI ranges enable one to easily estimate the maximum range that an object can be either detected, recognized or identified. Note: these estimates are based on the specified system, target, and environmental assumptions listed above. Actual performance may vary depending on operating conditions.
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: 2 pixels on target (Lower Bar) | 1.0 spatial cycle on target
- Recognition: 8 pixels on target (Middle Bar)| 4.0 spatial cycles on target
- Identification: 12.8 pixels on target (Upper Bar) | 6.4 spatial cycles on target
Hard-carbon AR Coating
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.
Designed for 640x480 Format LWIR Cameras
The SupIR 33.5mm f/1.3 lens is designed for use with 640x480 pixel array uncooled LWIR cameras with a 12 μm pixel pitch. It provides a 13.1° horizontal field of view.
