AR coating process

[samwkn]

May i know what is the correct process for the full AR Coating process?
This is the process that what i am running now;

1) Precleaning by Aceton
* is it need to clean 2 time in the precleaning process? ( clean by aceton --> ultrasonic clean --> clean by aceton again)
2) Detergent unit with 10% detergent
3) Ultrasonic Machine with detergent and DI water
4) Oven curing 30minute
5) Flow Box 15minute for cooling before hard coat
6) Dipping Hard Coat + precuring 68'C 4minute
7) Curing in Oven 3 hours 90'C
* is it need to be clean by Aceton + DI water in ultrasonic before coating AR? *
8) AR Coating

Did my process all right? Please advice. Thank you~

cleaning with acetone will make the lens attract dust and easier charge by static electricity through rubbing. Look up my website at http://optochemicals.com for more ideas on the subject.
