Positive Fresnel Lens SC 249
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 tolerance is ±5%, and the values are specified for 546 nm wavelength with PMMA material.
The standard material used is PMMA (Polymethyl Methacrylate) with a refractive index of 1.49 and relative dispersion of 58. Other materials are available upon request.
The standard thickness is 1.8 mm, but other thicknesses starting from 0.8 mm can be provided.
The facet spacing ranges from 0.076 mm to 0.762 mm, depending on the specific lens model.
Yes, outside diameter/size can be up to 5–20 mm beyond the clear aperture, and special dimensions or trimming can be requested.
Clear aperture sizes vary by model, ranging from 6.4 mm to 615.7 mm.
Yes, they are designed for applications requiring precision, including those needing specific focal lengths and clear apertures.
These lenses are ideal for applications in optical systems, light management, and imaging systems.
To calculate the number of lines per millimeter, divide 1 by the facet spacing of the lens.
