Advanced Vision System for Long-Term Infrastructure Monitoring

AR Coated ITO Coated Protective Window

A global OEM needed a vision system capable of withstanding extreme outdoor conditions for over a decade. This system, deployed across critical infrastructure sites worldwide, integrates multiple cameras and sensors within a ruggedized module.

Demanding Specifications

The front-facing window of the module had to meet the following specs:

  • High visible light transmission for clear imaging
  • Low UV and IR transmission to protect internal components
  • Integrated heat control to prevent fogging and ice buildup
  • Permanent bonding for long-term durability
  • High impact resistance to survive environmental hazards

Engineered Solution

JNS collaborated with the OEM to engineer a high-performance optical window with the following specifications:

Dual-Sided BBAR Coating

  • Type: Broadband Anti-Reflective (BBAR)
  • Location: Applied to both sides of the window in critical optical zones
  • Performance: Visible reflectance AvgR < 0.50%
  • Benefit: Maximizes light transmission while minimizing glare and reflection

Hot Mirror Coating (Shortpass Filter)

  • Cut-on Wavelength: 400 nm
  • Cut-off Wavelength: 700 nm
  • Function: Blocks UV and IR radiation while allowing visible light
  • Benefit: Protects sensors from thermal and UV damage, improving longevity

ITO Coating with Bus Bars

  • Material: Indium Tin Oxide (ITO)
  • Function: Transparent conductive layer with integrated bus bars
  • Purpose: Heats the window to prevent ice and condensation
  • Benefit: Maintains optical clarity in cold and humid environments

Double-Sided 3M VHB Adhesive

  • Type: Very High Bond (VHB) tape with release liner
  • Thickness: Customizable (as thin as 0.1mm)
  • Application: “Peel-and-place” installation for fast, secure bonding
  • Benefit: Eliminates the need for mechanical fasteners, ensuring a clean seal

Ruggedized Cover Glass

  • Material: Chemically strengthened aluminosilicate glass
  • Thickness: Range 0.4–2.0 mm
  • Impact Resistance: Up to 8x better than float glass
  • Benefit: Lightweight yet highly durable, ideal for harsh environments

Summary

JNS partnered with an OEM to develop a turnkey rugged optical window for global infrastructure monitoring. The solution features advanced optical coatings, integrated heating, and toughened, impact-resistant glass – engineered to deliver high performance and reliability for over a decade in extreme conditions.
