  • Example AR Coating Curve (Guidance only)

    AR coating curve chart showing percent transmission (%T) plotted against wavelength from 485 to 625 nanometres. The single curve forms a steep U-shape, starting near 1.0% at the shortest wavelengths, dropping to a minimum close to 0.02% around 545 nanometres, and then rising again toward 1.0% by 625 nanometres, indicating optimum antireflection performance near 545 nm.
