Dear K. Rattana,
According from phone call, normally lenses color after hard and AR coat should be within tolerance.
It should not clearly separate by visual.
Even the film properties can be passed the standard. The color should be confirmed also.
For the product lenses which are complete produced.
Please ask the acceptance from QA and QC side for this matter.
I could not make a decision can be sale or not?
In my opinion, the color much more differences (look like PNX color and CR 39 color).
Therefore it quite difficult to send it to customer
In the technical point of view, we must investigation what is the main root caused.
Please make discussion or please send us as much as information.
If the lenses from Cast are no problem, we must to check PRD1 liquid and temperature distribution between line 1 and line 2 also final cure oven.
Best regards,
H.Chonlatee
