Negative Fresnel Lens SC 239 neg
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 meeting 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
A negative Fresnel lens is used to diverge light, spreading incoming rays outward. It's commonly applied in beam expansion and projection systems.
The lens is constructed from high-quality optical-grade PMMA or glass, ensuring durability and high transmission.
The lens has a negative focal length, meaning it diverges light rather than converging it. The exact value is customizable.
The lens operates effectively across a wavelength range of 400 nm to 1100 nm.
Yes, the lens is suitable for laser beam manipulation and shaping in various laser applications.
The Fresnel design reduces the lens's thickness and weight while maintaining its optical performance, making it ideal for compact systems.
The lens features a 60/40 scratch-dig surface quality, which minimizes optical distortions and maintains image clarity.
Applications such as imaging systems, laser beam manipulation, and projection technologies benefit from the lens's precise light control and divergence.
The lens is designed to operate in temperatures ranging from -40°C to +80°C.
The lens has a diameter of 50 mm and a thickness of 2.5 mm.
