Single wavelength AR coating (V-coating)
Single wavelength AR coating (V-coating)
Single-wavelength AR coating (V-coating) is designed for specific laser wavelengths, achieving near-zero reflectivity and ultimate anti-reflection effects in the target band through a multilayer dielectric coating stack. Its core value lies in minimizing reflection loss at the designated wavelength (typically below standard values) while maintaining transmission stability in adjacent bands.
