Positive Fresnel Lens SC 208
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 widely used in optical systems for light management, including solar concentrators, projection systems, and magnifying optics.
The standard material for these lenses is PMMA (Polymethyl Methacrylate) with a refractive index of 1.49. Other materials are available upon request.
Focal lengths listed apply to 546 nm wavelength for PMMA, with a tolerance of ±5%.
Yes, the standard thickness is 1.8 mm or 2.5 mm, but custom thicknesses (≥ 0.8 mm) can be provided upon request.
Yes, special designs and dimensions can be customized to fit specific needs or project requirements.
The facet spacing determines the number of lines per millimeter, which influences the lens's optical performance and resolution.
The clear aperture varies depending on the model, with some apertures ranging from 10.0 mm to 615.7 mm, ensuring a wide range of options for different applications.
These lenses are optimized for a wavelength of 546 nm, but they can be designed to work efficiently at other wavelengths depending on the application.
The lenses can have dimensions up to 600.0 x 590.0 mm², with the outside diameter typically extending 5 to 20 mm beyond the clear aperture.
The focal length tolerance for these lenses is ±5% at 546 nm, ensuring precise optical performance.
