We offer optical-quality acrylic, polycarbonate, cyclic olefin copolymers (COC), and other specialized materials for the visible light spectrum, that also transmit somewhat in the near-infrared and ultraviolet as well.
FTI produces infrared transmitting Fresnel lenses in seven materials, each with unique transmittance capabilities for various applications.
Most widely applicable
General-purpose material in the visible light region
Transmittance is nearly flat and is almost 92% from the UV to the near-infrared
Available in standard, impact modified, UV transmitting and UV filtering grades
Offer acrylic-like transparency in the visible and UVA ranges with a higher index of refraction
Superior chemical resistance and lower water absorption than acrylic
Grades available with low birefringence, biocompatibility and/or resistance to high power NIR or blue light
Can be coated
Spectrally similar to acrylic
Useful at higher temperatures and very impact resistant
Standard thicknesses available in polycarbonate are 0.015" (0.38 mm), 0.030" (0.76 mm), 0.050" (1.3 mm), 0.060" (1.5 mm), and 0.125" (3.2 mm). 0.015" and 0.030" are the preferred thicknesses for polycarbonate, unless an item cannot be molded in one of those thicknesses

The template is really nice and offers quite a large set of options. It's beautiful and the coding is done quickly and seamlessly. Thank you!
It was easy to put together pages and when I was done, I could just click and have the page automatically created in HubSpot.
We built our old site using a template, and it left a lot to be desired. With SprocketRocket, we can go page by page and get the exact flow of content we need.
