Positive Fresnel Lens SC 210
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 of these lenses ranges from 6.3 mm to 763.4 mm, depending on the part number.
The standard material used is PMMA, 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, with some lenses available in 2.5 mm thickness. Custom thicknesses of 0.8 mm or greater are also possible.
Yes, special designs, dimensions, and trimmings are available upon request.
The clear aperture varies from 6.4 mm to 615.7 mm, depending on the lens model.
Yes, the focal length tolerance is ± 5%, measured at 546 nm for PMMA material.
The number of lines per mm is calculated by using the inverse of the facet spacing.
These lenses are optimized for use at 546 nm, but they can be designed for other wavelengths upon request.
Yes, the outside diameter or size can be adjusted up to 5–20 mm beyond the clear aperture to meet specific design requirements.
The facet spacing varies from 0.076 mm to 0.762 mm, depending on the lens model.
