Positive Fresnel Lens SC 928
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 focal length range varies from 6.3 mm to 763.4 mm, depending on the specific lens model.
The lenses are made from PMMA (Polymethyl Methacrylate) with a refractive index of 1.49 and a relative dispersion of 58.
The facet spacing ranges from 0.076 mm to 0.762 mm, depending on the model.
The standard thickness is 1.8 mm, with some models featuring a thickness of 2.5 mm. Custom thicknesses of 0.8 mm or more are also available upon request.
Yes, custom designs, including special trimmings and dimensions, are available upon request.
The lenses are optimized for 546 nm light, with a tolerance of ±5%.
Yes, while PMMA is the standard material, other materials are available upon request for specialized applications.
The number of lines per mm can be calculated by using the inverse of the facet spacing value (1/facet spacing).
The largest lens, SC 213-600, has a focal length of 763.4 mm and a clear aperture size of 600.0 x 590.0 mm², with a thickness of 2.5 mm.
