For night vision & thermography

Infrared (IR) Anti-Reflective (AR) Coatings

Producing vivid infrared sensor images and video by using anti-reflective effects optimized for infrared-rays

Overview

The protective covers (window applied) for the infrared sensors used in night vision and thermographic goggles use materials like silicon and germanium that easily transmit infrared rays. However, these materials also reflect infrared rays at a high frequency, making the suppression of those reflections necessary to improve performance. With Geomatec's Infrared (IR) anti-reflective (AR) coatings, the reflection of infrared rays is effectively minimized, contributing to improved thermographic and night-vision performance.

  • Point1By coating on both sides, average transmittance of infrared rays (in the 8-14 µm wavelength range) is improved by 78%*1
  • Point2Anti-reflective coatings can be customized for optimization with specific infrared ray wavelengths
  • Point3They can also be coated directly to 8 inch silicon wafers
  • Point4Infrared (IR) anti-reflective (AR) coatings with advanced DLC*2 are also possible

  2. *2DLC (diamond-like carbon) coatings: Amorphous hard carbon film with a materiality that falls between diamonds and graphite. It can be applied to all varieties of substrate surface to strengthen durability (hardness) and infrared ray transmittance

Specifications & Data

Example specifications

By layering optical films that are optimized for infrared rays, it is possible prevent reflection and ensure vivid images and video from infrared sensors. For example, if Infrared (IR) anti-reflective (AR) coatings are applied to both sides of the silicon wafer used with protective covers (window applied), the average transmittance of wavelengths in the 8-14µm range increases to 78%.

Graph: With wavelengths in the 8 - 14 µm range, average transmittance for unprocessed silicon wafer is 49.5%. In contrast, silicon wafers with AR coating applied on both sides achieved a transmittance rate of 88.0%. The difference is plain to see.
