Positive Fresnel Lens SC 2045
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 lengths are listed for 546 nm with a tolerance of ±5%.
The standard material is PMMA (Polymethyl Methacrylate), with a refractive index of 1.49. Other materials are available upon request.
The standard thickness is 1.8 mm, but other thicknesses (≥ 0.8 mm) are possible.
The number of lines per millimeter can be calculated by using 1 divided by the facet spacing of the lens.
Yes, special designs and dimensions can be made upon request, with the possibility of custom trimming and modifications.
The outside diameter or size may be up to 5–20 mm beyond the clear aperture, depending on the lens design.
The focal lengths are optimized for 546 nm, but lenses can be customized for other wavelengths if requested.
The lenses are made of PMMA, which is suitable for various applications, but for specific environmental conditions, additional coatings or materials may be required.
The relative dispersion of PMMA is 58.
Yes, special trimmings and dimensions can be realized based on customer requirements.
