The Red Spray Formula First Contact polymer solution from Photonic Cleaning Technologies facilitates cleaning of any size or shape optic, mirror or crystal without touching the delicate surfaces. The polymer film prevents recontamination. The solution cleans and protects precision surfaces and optics made of glass, fused silica, silicon, crystals, nonlinear crystals, metals, Ge, ZnSe, NaCl, KBr, KRS-5, first-surface mirrors and optical thin films, including antireflection and reflective coatings. The red color is not added to the solvent but is in the polymer, so it leaves no residue. The solvent removes dust, fingerprints and other contamination without scratching or otherwise damaging sensitive surfaces.
