FAQ: I saw other manufacturers claim better reflectance. What's difference?
Marumi’s factory lab research demonstrates a consistent performance with an average reflectance of 0.18% across the visible spectrum (400-700nm). This isn't just a one-off peak performance but a steadfast guarantee across all wavelengths that matter.
Have you already heard the word of photography like “F-stops”, “Filter Factor”, “Optical Density” or “Transmission rate”, and somehow you vaguely understand what they really mean?
If yes, the chart and description below enable you precisely to understand the correlation comprehensively.
