Positive Fresnel Lens SC 922
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 the lenses ranges from 6.3 mm to 764.0 mm, depending on the specific part number.
The standard material used is PMMA (Polymethyl Methacrylate), which has a refractive index of 1.49 and relative dispersion of 58.
The standard thickness of the lenses is 1.8 mm, with some models available in 2.5 mm thickness. Other thickness options (≥ 0.8 mm) are also available upon request.
The focal lengths listed apply to a wavelength of 546 nm for PMMA.
Yes, outside diameters or sizes can be customized with dimensions beyond the clear aperture by 5-20 mm. Special trimmings or designs are also available upon request.
The number of lines per mm can be determined by using 1/facet spacing, where facet spacing is provided for each part number.
Yes, while PMMA is the standard material, other materials can be used upon request.
Most lenses have a conjugate of infinity on one side, with varying conjugate distances on the other side depending on the specific part number.
The clear aperture of the lenses can range from 6.4 mm to 600.0 x 590.0 mm², depending on the part number and model.
Yes, these lenses are engineered to manage light effectively and can be used in high-precision optical systems for focusing and directing light.
