Complete the procedure by wiping with a clean lens tissue as in 1b) above. After this type of cleaning, washing with acetone is recommended to remove all traces of the liquid cleaner. Again a finger inside a latex glove is a suitable tool for removing stubborn marks. These generally come in three types bare metal, coated metal (usually with gold) and enchanced coatings (dielectric coatings - e.g., phase retarders or circular polarising optics orsilicon mirrors).īare metal optics (usually copper) can be cleaned if in a very dirty condition using liquid proprietary metal polishers. In addition alcohol evaporates more slowly than acetone and generally leaves more residues on the surface. This is acceptable but care should be taken to prevent the solvent reaching the fingers as it may dissolve oils which can be deposited on the optic. Some people use ethyl or methyl alcohol in place of acetone. Repeat the above step until the optic is clean. Note that the dry part of the tissue helps remove acetone residue. Lower the lens tissue onto the optic and pull it over the surface.

Hold a piece of lens tissue above the mirror and place a few drops of acetone on the paper.

Always hold the optic at its edge or place on a clean drywork surface on a lens tissue. Acetone and the 'drop and drag' technique are recommended.

After the above preparatory cleaning, (which is not always necessary), the optic is ready for a final cleaning.

When complete wipe with clean white tissue. A finger inside a latex glove is a useful tool for stubborn marks.

Gently flush the part with the solution being careful not to abrade the surface. This may be done by washing in soapy warm water using a mild liquid detergent, or acetone. Completely remove all excessive amounts of oil, grease, dirt and other contaminants.The coatings on the silica optics commonly used with high power Nd:YAG lasers are very durable and usually harder than the substrates themselves.
