We need a lens with a diameter of at least 24''. We are having trouble finding this big of a lens. Can your company help us do this?
Also we are looking for transmittance data on that lens such as 99.? % of light passes through, and the possibility of adding an anti-reflective coating to the lens.

"How can we reduce delivery time?"
In developing stage of fresnel lens, most of customization requires to invest huge money and time for designing and molding. It is also the most important factor on deciding delivery lead time, which we try our bests to reduce for customers.
Even though the long delivery lead time conflicts with our value, the trade-off between delivery and customer’s needs is can be realized.
