Looking for abrasion resistant and anti-reflective polycarbonate sheet.

Flashlight Modding and DIY Parts

Is there such a thing as Polycarbonate sheet with one side anti-abrasion and the other side anti-reflective? As you might guess I want the AR coating facing in and the anti-abrasion coating facing out. This is for an automotive light bar.

Let me know if you have know of such a thing.

Thanks.

I know individual lenses but not sheet:

Used this for a flashlight and it was pretty tough to scratch.

Thanks, but I need it Polycarbonate, not Acrylic, and needs to be sheet. Those would be good for flashlights no doubt.

Look to the window manufacturers for ready made coated sheet. Parker “Duralan II” is one example I found: http://www.parker.com/literature/Chomerics/Duralan-II-prnt.pdf
Otherwise, there are many companies who specialize in coatings of this sort but the cost is probably prohibitive for a single order.

Vapor deposited AR coatings will provide you with some 3-5% more output but the cost difference may be significant vs uncoated sheet.
