Fresnel Lens Optical Lenses
from ORAFOL Fresnel Optics GmbH
Lenticulars have linear structures where every groove has a small radius creating multiple line images. They are primarily used for projection screens and three dimensional images. The designs can be trimmed according to customer requirements (within limits of clear aperture). Optical coatings for... [See More]
- Lens Type: Fresnel Lens
from Changchun Yutai Optics Co., Ltd.
Fresnel Lens is a specially designed optical lens that focuses or diverts light by breaking down the curved surface of a conventional lens into a series of small concentric rings of prisms. This design allows the lens to maintain its optical performance while significantly reducing the amount of... [See More]
- Lens Type: Fresnel Lens
- Surface Flatness: λ/4
- Surface Quality: 40-20 Scratch / Dig
from ORAFOL Fresnel Optics GmbH
A negative Fresnel lens is the opposite of a positive Fresnel lens with diverging light rays. The designs can be trimmed according to customer requirements (within limits of clear aperture). It is possible to combine a Fresnel lens structure with other structures like diffusers or microlens arrays... [See More]
- Lens Type: Fresnel Lens
- Focal Length: -186
from ORAFOL Fresnel Optics GmbH
Positive Fresnel Lenses can be designed as a collimator, collector or with finite conjugates. They are usually corrected for spherical aberration. The designs can be trimmed according to customer requirements (within limits of clear aperture). It is possible to combine a Fresnel lens structure with... [See More]

from Shanghai Optics
Fresnel Lens Overview. Fresnel lenses are lenses composed of a series of concentric rings. The Fresnel lens construction design allows for large aperture and short focal length with less mass and volume compared with a conventional lens design. Fresnel lens were invented by French physicist Augustin... [See More]
- Lens Type: Fresnel Lens
from Edmund Optics Inc.
A Fresnel lens replaces the curved surface of a conventional lens with a series of concentric grooves, molded into the surface of a thin, lightweight plastic sheet. The grooves act as individual refracting surfaces, like tiny prisms when viewed in cross section, bending parallel rays in a very close... [See More]
- Lens Type: Aspheric; Fresnel Lens
from Knight Optical (UK) Ltd
Fresnel lenses consist of a flat surface with interspaced, concentric steps whereby each step corresponds to the surface of a conventional lens. Each step thereby acts as a refractive surface, much like a prism. This gives the fresnel lens a common focal length equivalent to a traditional lens, but... [See More]

from Knight Optical (UK) Ltd
Lenticular lenses are comprised of regular lines of cylindrical lenses on a flat surface that efficiently divide, focus and diffuse light rays. This type of lens sheet is used for projection screens and stereoscopic (3D) photos. Every component is individually tested by our highly skilled... [See More]
