A breakthrough technology, "Plasma Sputtering" coating pursuing the top of the top polarizer realized the Marumi Prime Plasma Sputtering C-P.L (Plasma CPL), which enabled an extremely clear vision even under a backlight scene by lowering the reflectance to the limit, almost perfectly neutralized color balance, and the spectacularly enhanced scratch-resistant performance.

Absolutely close to the neutral gray, redressing the yellowish color balance that originated from Polarizer. Contrast-enhanced, more saturation is provided, and the blue sky will be vividly deepened.
The Plasma Sputtering coating technology implemented/ Twenty-eight layers in total on both sides with a reflection rate under 0.18% (400-700nm average)
Static quick discharge works wonders on the surface of the glass, which is structured to prevent static electricity. Dust and dirt are hardly adhered to the surface; even if they do, the blower blows them off quickly and easily.
Water-/oil repellence sheds water simply by the air blower. Nuisances such as sweat, skin crème, lotion, fingerprints, or compounded grease stains will be wiped off.
While color neutrality is given priority to avoid a yellowish color shift, the transmittance rate remains approximately 33%. (400-700nm average)
Realized an ultra-thin aluminum rotating structure to avoid vignetting.
Knurling embedded in the lightweight frame enables easy and smooth handling.
Made in Japan, lamination technology has been indurated by decades of technical succession.
