Optical element cleaning agent and cleaning method thereof

[0026] Cleaning CeO after grinding of general optical lenses 2 Pollution and residual, can use described cleaning water agent I and cleaning water agent (II), wherein the raw material formula (weight percentage) of cleaning water agent I is sodium hydroxide (0.2%), sodium tripolyphosphate (0.2%), Emulsifying penetrating agent (OP-10) (0.2%), the raw material formula (percentage by weight) of cleaning agent (II) is sodium silicate (0.2%), sodium dodecylbenzene sulfonate (0.2%), emulsifying penetrating agent (AES) (0.2%), so that the concentration of the aqueous solution is 0.5%, the temperature of the aqueous solution is 50±5°C, the use conditions are that ultrasonic waves can be assisted, and the conductivity of pure water is greater than 8MΩ.

[0027] Cleaning steps:

[0028] ① Put the optical lens into the cleaning agent (I), and clean it with ultrasonic wave for 100s;

[0029] ② Put the optical lens into the circulating pure water and perform ultrasonic cleaning for 110s;...

[0035] For a small amount of oil stains (after solvent) and fingerprint residue after the optical element is cored, the cleaning water agent I and the cleaning water agent II can be used, wherein the raw material formula (weight percentage) of the cleaning water agent I is sodium hydroxide (0.15%) , sodium tripolyphosphate (0.15%), emulsifying penetrant (OP-10) (0.15%), the raw material formula (percentage by weight) of cleaning agent (II) is sodium metasilicate (0.2%), lauryl Sodium benzenesulfonate (0.2%), emulsifying penetrant (AES) (0.2%), and make the concentration of the aqueous solution 2.5%, the temperature of the aqueous solution is 75±5°C, the conditions of use are that ultrasonic waves can be assisted, and the conductivity of pure water is greater than 8MΩ .

[0036] Cleaning steps: ① Soak the optical lens in cleaning water agent I for 60s;

[0037] ②Put the optical lens into the circulating and filtered cleaning water (I), and ultrasonically clean it for 100s

[0044] Considering the particularity and requirements of the surface of the coated lens, the lotion must be adjusted according to the actual situation, mainly for fingerprints and dust pollution. The cleaning water agent II and the cleaning water agent I can be used, and the cleaning water agent I Raw material formula (weight percentage) is the raw material formula (weight percentage) of sodium hydroxide (0.25%), sodium tripolyphosphate (0.25%), emulsification penetrating agent (OP-10) (0.25%), cleaning water agent (II) It is sodium silicate (0.2%), sodium dodecylbenzenesulfonate (0.2%), emulsifying penetrant (AES) (0.2%), and the concentration of the aqueous solution of cleaning agent II is 0.5%, and the temperature of the aqueous solution is 50±5 °C; the concentration of the aqueous solution of cleaning agent I is 0.1%, and the temperature of the aqueous solution is 25±5 °C; the use conditions are all ultrasonic-assisted, and the conductivity of pure water is greater than 8MΩ...
