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

What is the purpose of the Negative Fresnel Lens DC 434U neg?
It is used to diverge light, making it suitable for beam expansion and defocusing applications.
What material is the lens made of?
The lens is made from high-quality optical-grade materials for enhanced durability and clarity.
How does the negative focal length impact light behavior?
The negative focal length causes light rays to spread outward, which aids in beam shaping and expansion.
What are the common applications for this lens?
It is commonly used in imaging systems, laser beam shaping, projection systems, and scientific research.
How does a Fresnel lens differ from a traditional lens?
Fresnel lenses are thinner and lighter due to their concentric grooves, which control light with less material.
Can this lens be used in compact devices?
Yes, its lightweight and thin design make it ideal for use in space-sensitive optical systems.
Does the lens work effectively across different wavelengths?
Yes, the lens provides high optical efficiency across a broad range of wavelengths.
How does the Fresnel design benefit optical performance?
The Fresnel grooves reduce aberrations and allow for precise light control in a compact form.
What industries typically use this lens?
It is widely used in scientific research, imaging technology, laser systems, and projection systems.
