The differences between Large caliber MWIR camera and normal one

The main differences between a large caliber MWIR (Mid-Wave Infrared) camera and a normal MWIR camera come down to performance, durability, and intended use case. Here's a breakdown:

1. Purpose & Use Case

Large caliber MWIR camera: Designed to be mounted on or used near large caliber weapon systems (e.g., tanks, artillery, naval guns). Built to handle high recoil, shock, and vibration.

Normal MWIR camera: General-purpose thermal imaging camera used for surveillance, industrial inspection, search and rescue, etc.

2. Mechanical Robustness

Large caliber: Reinforced housing, ruggedized for military-grade shock and vibration resistance, including the shock from firing heavy weapons.

Normal: Less rugged; may not survive the mechanical stress of a large caliber weapon firing nearby.

3. Optical Performance

Large caliber: Often has higher resolution optics and longer focal lengths for extended-range target detection and identification.

Normal: May have shorter focal lengths optimized for medium or short-range imaging.

4. Thermal Sensitivity (NETD)

Large caliber: Typically optimized for high sensitivity to detect faint thermal signatures at long distances.

Normal: May have slightly lower sensitivity or be optimized for broader temperature ranges, depending on the application.

5. Integration

Large caliber: Integrated into fire control systems, with ballistic computation, target tracking, and aiming assistance.

Normal: Standalone or networked system, typically not integrated into weapon targeting systems.

6. Cost

Large caliber: Much more expensive due to specialized design and military-grade specs.

Normal: More affordable and widely available for commercial or civilian use.

7. Environmental Sealing

Large caliber: Often sealed to military standards (e.g., MIL-STD-810), ensuring operation in harsh environments.

Normal: May have IP-rated sealing, but not necessarily military grade.
