Fresnel Technologies,
Inc. makes a wide variety of stock optical components
to meet the customers¡¯ needs; including design and
construct custom items as necessary. The itemsfall
into a number of categories, but they all have a few
things in common: they are made from plastics aterials,
they are thin (generally under 1/4" [6mm]), and they typically havestepped
surfaces.
These items generally fall into the following categories:
- Positive focal
length aspheric Fresnel lenses
- Cylindrical (actually
acylindrical) Fresnel lenses
- Negative focal
length aspheric Fresnel lenses
- Off-axis Fresnel
lenses
- Lenticular arrays
- Arrays of prisms
(Fresnel prisms)
- Rectangular arrays
of Fresnel lenses
- Microlens arrays,
both rectangular and hexagonal symmetries, as well
as custom symmetries
The various items
are discussed in detail, along with materials for
visible light, near infrared, and ultraviolet
light applications, in Fresnel
Lenses brochure*.
*The
prices on the back of the Fresnel lens brochure are
