Photography enthusiasts and professionals know that the secret to capturing perfection often lies in the details. One such critical detail is the glass's reflectance —a measure of how much light is reflected from the surface of the filter. Lower reflectance means higher image clarity and less glare.
Some manufacturers indicate reflectance or transmittance values without clarifying their measurement conditions. However, such figures often represent a single minimum or maximum point on the reflectance or transmittance curve under specific circumstances, not the overall performance across the visible spectrum.
Marumi, on the other hand, discloses the typical reflectance value of 0.18% for the Plasma CPL, measured consistently across the visible range (420–680 nm, average). This value represents the typical performance rather than an isolated “champion” data point, providing reproducible and accurate values of real-world results.
Through precise in-house testing and strict quality control, we ensure that every Plasma CPL maintains a typical reflectance of 0.18% across the visible range — ensuring higher clarity, reduced glare, and faithful color reproduction.
