CRAFT & OPTICS
L39 OPTICAL GLASS. PURE SPECTRAL CLARITY.
Atmospheric ultraviolet scatter produces subtle haze and chromatic fringing across high-altitude and coastal scenes. XT UV filters use genuine L39 optical glass to absorb UV light below 390nm while hydrophobic and oleophobic outer coatings repel sea spray, dust, and fingerprint oils in the field.
390NM UV ABSORPTIONAbsorbs ultraviolet wavelengths below 390nm directly within the glass melt, cutting environmental haze without digital post-processing.
HYDROPHOBIC NANO-SEALMulti-layer water- and oil-repellent coating makes droplet wipe-downs fast and streak-free without degrading antireflective coatings.
