Optical Lens Cleaning
Q. How do you clean wax marks on optical lenses which are difficult to remove?
A. Use either 1% Alconox or Liquinox in a heated 160 deg F ultrasonic bath followed by a deionized water rinse to clean optical lenses during manufacturing.
Stripping NiCr-AG-NiCr Coating
Q. To strip NiCr-Ag-NiCr coating, I was preparing a solution @4% of Cerium Ammonium Nitrate (C.A.N.)and I added Citrajet @1% to be used as a wetting agent (surface inclined). The addition of Citrajet neutralized completely the effect of the C.A.N; which did not attack the NiCr layers. Can you give me some explanation and which Alconox product I have to use as wetting agent.
A. CAN is a very strong oxidizing agent. Organic functional groups with double bonds, alcohols, benzene rings and ethers are likely to be oxidized by CAN, thereby “neutralizing,” or depleting it, thereby rendering it less effective for stripping coatings. Most wetting agents have organic functional groups that will be oxidized by CAN, including Citrajet.
Using Liquinox as Optical Cleaner
Q. We have some problems about coloring and exfoliation of partly chromate conversion applied surface. We are trying to find a solution. Is it possible to use Liquinox to clean alodine applied parts or not? Click for the answer . . .
Removing Latex from Optical Cuvette
Q: How do I remove latex particles from an optical cuvette.
A: We recommend you use a warm 1% Alconox detergent followed by a warm water rinse to clean the optical cuvettes.
Lens Cleaning During Manufacturing
Q. How do you clean optical lenses during manufacturing? A. To clean optical lenses, typically you use warm (120 deg F or 50 deg C) solutions of 1% Liquinox in an ultrasonic bath followed by a thorough rinse.
