Spectral Response Curve
Bare Glass
Uncoated soda-lime glass: ~91% transmittance, ~8% total reflection (both surfaces).
Your Config
Selected coating and substrate combination — performance varies by wavelength.
Ideal Target
Theoretical maximum: 100% transmittance, 0% reflectance (reference line).
Technical Note: Transmittance values are calculated using Fresnel equations for normal incidence, with absorption modeled via Beer-Lambert law. Multi-layer AR performance is based on standard broadband anti-reflection (BBAR) design with MgF₂/ZrO₂/Al₂O₃/SiO₂ stacks. Values are theoretical approximations — actual performance may vary by ±1–2% depending on manufacturing tolerances. Contact our engineering team for measured spectral data.
