IR Materials advantages

Apr 19,2021

VY OptoelectronicsVY, a renowned provider of optical components, vy can provide a variety of infrared material products including germanium and siliconIR materials are appropriate for applications such as electro-optic sensors, medical imaging,missile and rocket windows, spectroscopy, and thermal imaging. 


Advantages of silicon materials

  • Cubic in nature and will not exhibit birefringence
  • High environmental durability
  • Silicon is lower in density making it ideal for weight-sensitive applications when compared to other popular IR materials such as germanium and zinc selenide
  • Thermal stability
  • More cost-effective for mid-wave applications than other IR materials

Advantages of germanium material

  • Highest refractive index and lowest optical dispersion of commonly available IR-transmitting materials
  • Germanium is relatively hard with high-density making it ideal for IR applications requiring rugged optics
  • Generally, an anti-reflection coating is recommended on germanium windows for sufficient transmission in the region of interest
  • Subject to decreases in transmission as temperature increases, therefore, it must be used at temperatures below 100°C
  • Germanium makes an effective 50:50 beamsplitter without the need for coatings
