PRODUCTION OF LENSE USING PMMA.

[possibilita]

pls could somebody give me some tips on the production of lense using polymethylmethacrylate as the base polymer?and a well formulated table will be appreciated

Perhaps you should contact a PMMA manufacturer or PMMA lens manufacturer. I would presume that this is usually proprietary information.

I've worked with PMMA and it's fine for some things. Keep in mind that if you are casting you will be working with a finished material that is not fully cross linked, which can lead to free radicals and interactions with oxygen. If you are injection molding then you need to find an optical grade PMMA. Tooling with these materials is very expensive and it is difficult/expensive to hold tolerances comparable glass optics. Have you considered using an optical grade silicone? I've found that some of the new injection moldable optical silicones have superior properties to thermal plastics and they are less expensive to tool. These materials are also great for prototyping. Clarity is same as PMMA, temperature range is up to 200 C and over, yellowing in UV is not a problem. I could go on and on.
