- Thickness: 3mm
- Pitch/groove: standard (we are open to your suggestion)
- Quantity: 10
Please know that this is an angle bending lens. This means that is has parallel similar prisms all over the surface. Attached are the drawings of the prisms and also a snapshot of a sample lens.
Please let me know your pricing including tooling fee, price per lens and "lead time" for 10 lenses.

Yes - it is possible to use smaller pieces. Even 5"x5" square pieces with the proper prism patterns can be tiled together to generate the appropriate effect we are looking for (which is angle bending the light).

Diameter 23inch is too big for linear type lens.
Could you make smaller or split into several pieces?
Now we are on vacation until upcoming Sunday, therefore my answer can be delayed.
