Quote:I have seen the small spots you refered to when cleaning. They have always been the result of contaminated cleaning cloths, the most recent example, ( I start cleaning by blowing off the lens with a bulb blower followed by brushing the surface with a Edmund Optics lens brush to loosen any particles along the edge of the lens, then blowing again), was caused by ( eyelash oil? ) contamination on the brush. Cleaning the brush with alcohol fixed that issue. I would be very suspicious of any lens cleaning cloths that were not new out of the package. Purosol is a very good cleaner but remember, any cleaner just suspends the oil or grease and that can find its way onto the cleaning cloths etc to be re-deposited again. Rex

All MY reflectors are apochromatic. I am personally covered with infrared detectors and emit at 295 Kelvin, 24/7. If I were to recieve a spin entangled photon before you recieved its twin, MY photon would predict your photon's spin. Every time. MY family's lineage goes back over three billion years and has a whole branch of science devoted to studying it... The most Quotidian of observers
Quote:The link said alcohol from the hardware store is ok.Would that be "Isopropyl" or "Denatured" alcohol?Acetone is used to strip finishes, paint, laquer etc. Too strong in my opinion.

Quote:I tried a number of cleaners and methods and was never really happy with the results. There was always a streak or residue and I felt like I had to go over the optical surface multiple times (risking damage).
