The LensPen ® is a convenient and compact solution to optical cleaning. The two-part cleaning system includes a soft-bristled brush which can be used to remove rough particles and access hard-to-reach areas. Remove the cap on the other end and a cleaner pad with a special non-liquid compound can be used to wipe away smudges and other marks without damaging the lens. Replace the cap when done to apply fresh solution to the pad. The Lenspen ® MiniPro is also available for smaller lenses.
