Looks like it's just dirty. Pretty easy to clean. It uses glass optics I'm sure. (Mine does) which can be cleaned no contact with lab purity acetone or methanol.. 91% isopropyl alcohol on a fresh cotton swab/q-tip VERY GENTLY rubbing in ONE DIRECTION can sub in a pinch. But whatever you do don't scrub. The optics are easily degraded by any kind of contact so the least pressure the better.
