Positive Fresnel Lens SC 948
Description
Our SC series lenses are crafted through advanced injection molding and compression molding technologies, insuring a superior surface quality and by that optical performance.
The unique design of our polymer Fresnel lenses not only ensures optimal optical performance but also offers significant advantages. Compared to traditional glass lenses our lenses provide substantial weight, space and cost reductions making them indispensable in lighting, sensor, and machine vision applications.
At ORAFOL Fresnel Optics we take pride in offering comprehensive solutions, from optical design and prototyping to tooling and high-volume production. Whether you choose one of our standard products or opt for a custom solution, including high-volume production, we are committed to meet your specific requirements.
Customization options include precise trimming to desired shape, changing of thickness (>0.8 mm) and material (PMMA, Polycarbonate, silicone on glass), optical coating (reflective and anti-reflective coating of various kinds) and combination with other components (diffusive microstructures, microlens arrays) directly into the plano side of the lens. A completely new design of the microstructure specificly made for your application including tooling and prototyping is also possible. Contact us for details.

Frequently Asked Questions
Positive Fresnel lenses are commonly used in solar concentrators, illumination systems, and optical instruments requiring light collection or focusing.
The standard material used for these lenses is PMMA (polymethyl methacrylate), with a refractive index of 1.49. Other materials are available upon request.
The focal lengths listed apply to 546 nm for PMMA and have a tolerance of ±5%.
Yes, the lenses can be customized. Thicknesses of 0.8 mm or greater are possible, and outside dimensions can be adjusted beyond the clear aperture size.
The number of lines per mm is calculated by using the reciprocal of the facet spacing.
PMMA lenses are generally not suitable for high-temperature applications. For such environments, alternative materials can be used upon request.
The standard thickness is 1.8 mm for most lenses, although other thicknesses are available.
Yes, custom designs and additional optical features can be requested to meet specific application requirements.
Specifications are subject to change without prior notice, and tolerance levels may vary depending on the application.
Yes, positive Fresnel lenses can be used effectively in both reflective and transmissive systems, depending on the design.
