Product Features:
■ 3-layer construction with high abrasion resistance
Fircrest Ultra IRND filters feature a three-layer construction that bonds an IRND coating with two optical glass.
This ensures that the coating is completely protected from external factors, improving abrasion resistance and service life.
■ Rare earth metal coating that enhances neutral.
The IRND filter coating uses a "rare earth metal coating" that absorbs almost every wavelength range of light (ultraviolet rays, visible rays, near infrared and infrared rays).
Compared to other glass filters, it has been significantly improved in color cast, especially due to IR (infrared range).
■ High flatness with precision glass polishing technology.
"Wrap & Polished" (Glass Polished) ensures high clarity and sharpness that you expect as a high-end class filter.
■High quality SCHOTT B270® glass
The optical glass uses SCHOTT B 270® glass with high transmittance and low refraction. SCHOTT B 270® glass has stable transmission properties of ultraviolet (UVA) to near infrared rays, and a very low refractive index.
Resistant to reflections and flares, water repellent, maximizes filter performance
■Edge ink processing
The side of the filter is applied to the side of the filter to reduce inner reflections and prevent flare and ghosting.
