  • Example AR Coating Curve (Guidance only)

    AR coating curve chart titled “440–850 nm BBAR on <110> TeO2,” showing reflection percentage plotted against wavelength from 400 to 850 nanometres. The single curve begins at about 4.5% reflectance near 400 nm, falls steeply to below 1% by roughly 445–450 nm, then remains low and relatively flat across most of the broadband range. It reaches its lowest point at around 720 nm at approximately 0.25% reflectance before rising gradually again toward about 0.9% at 850 nm, illustrating broadband antireflection performance across the visible and near-infrared range.
