Zinc Selenide (ZnSe) has the lowest absorption of the common CO2 transmitting materials and is, therefore, the material of choice for high-power applications. It is also the only material that transmits visible light, a requirement for the use of a HeNe alignment laser.
Advantages

  • High Quality Material.
  • Excellent Durability.
  • Excellent Beam Quality.
  • Excellent Performance

Gallium Arsenide (GaAs) is the material of choice in dirty or highs platter environments. It has relatively high hardness which helps repel debris particles. It also has high thermal conductivity which helps transmit heat away from imbedded particles.
