Laser Optics Antireflection Coating
Product Details:
Antireflection coating on optical components for laser wavelengths is designed with suitable dielectric multilayer to have a low absorption, minimum surface reflection loss with high damage threshold.Antireflection coating on optical components for laser wavelengths is designed with suitable dielectric multilayer to have a low absorption, minimum surface reflection loss with high damage threshold. The designed layers are electron beam deposited under the presence of high energetic ion beam to increase the packing density and stoichiometry and monitored through optical thickness monitor to ensure the close match of the design to achieve the desired transmittance with batch by batch consistency. This advanced deposition technology offers the high resistance to laser damage, making them suitable for high-energy laser usage with minimum transmission loss.
