Positive Fresnel Lens SC 213-600
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
The product offers a wide range of focal lengths from 6.3 mm to 764.0 mm, providing versatility for various applications.
The standard thickness is 1.8 mm for most models, with some variants available in 2.5 mm. Other thicknesses (≥ 0.8 mm) are also available upon request.
The lenses are made from PMMA (Polymethyl Methacrylate) with a refractive index of 1.49. Other materials can be requested based on specific needs.
The facet spacing varies by model, with values ranging from 0.076 mm to 0.762 mm. To determine the number of lines per mm, the formula 1/facet spacing is used.
Yes, customization is available for outside diameter, thickness, and facet spacing. Special designs can also be requested to meet unique application requirements.
The clear aperture varies by model, with sizes ranging from 6.4 mm to 615.7 mm. It is possible to have up to 5-20 mm beyond the clear aperture for specific dimensions upon request.
The focal lengths listed apply to 546 nm for PMMA and have a tolerance of ±5%.
Yes, the lenses are optimized for specific wavelengths, with focal lengths applying to 546 nm for PMMA, but they can be designed for other wavelengths upon request.
These Fresnel lenses are ideal for optical systems, projection systems, solar concentrators, and other applications where precise light control and focusing are required.
While the lenses follow standard specifications, there are few limitations. Special thicknesses, trimming options, and other customizations can be discussed to meet specific needs.
