Thermal Imaging System for Search & Rescue Operations

Defense & Security Contractor

Provided ruggedized Germanium optics with DLC coating for handheld thermal imagers deployed in search and rescue operations worldwide. Field-proven durability and enhanced detection range.

The Challenge

The client needed ruggedized optics for handheld thermal imagers operating in extreme conditions:

  • Durability in harsh field conditions including temperature extremes and physical impact
  • High transmission in 8-14μm LWIR range for optimal detection
  • Lightweight design for portable systems carried by first responders
  • Scratch and abrasion resistance for field deployment
  • Optical performance consistency across operating temperatures

Our Solution

Our comprehensive solution for defense and security applications:

  • Germanium optics with DLC coating for superior scratch resistance
  • Aspheric lens design for compact, lightweight optics
  • AR coating optimized for LWIR (8-14μm) with >98% transmission
  • Ruggedized mounting interfaces for shock and vibration resistance
  • Environmental qualification testing including thermal cycling and salt spray

Results

Successful deployment and operational results:

  • Field-proven durability with zero coating failures reported
  • Improved detection range by 25% compared to previous optics
  • Deployed in 500+ units with military and civil defense agencies worldwide
  • Operational temperature range extended from -40°C to +60°C
  • Reduced system weight by 18% through optimized optical design
