Positive Fresnel Lens SC 2135
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 range from 6.3 mm to 763.4 mm, depending on the specific model. Each model's focal length is optimized for its intended application, making the lenses versatile across a wide range of optical systems.
The lenses are made from PMMA (polymethyl methacrylate), with a refractive index of 1.49. Other materials are available upon request for specific application needs.
The standard thickness for the lenses is 1.8 mm, with certain models available in 2.5 mm. Custom thicknesses starting from 0.8 mm are also possible.
The facet spacing ranges from 0.076 mm to 0.762 mm, depending on the model. This affects the lens's optical resolution and light management capabilities.
The lenses are designed for use with 546 nm wavelengths, with a tolerance of ±5%. Custom designs for other wavelengths can be created on request.
The clear aperture varies between models, ranging from 6.4 mm to 600 mm, allowing them to cover a broad spectrum of applications in optics and imaging.
Yes, custom designs, sizes, and trimmings can be made upon request. Special requirements like different focal lengths, facet spacing, or aperture sizes can be accommodated.
The number of lines per mm can be calculated by taking the reciprocal of the facet spacing (1/facet spacing). This provides the density of lines that influence the lens's resolution and performance.
The focal lengths listed apply to 546 nm light with a tolerance of ±5%, ensuring precise light focusing and control for various applications.
The lenses are primarily made of PMMA, which offers good optical clarity and durability. However, additional details about their environmental stability can be requested based on specific applications.
