Fresnel Lenses are lightweight optical components engineered to focus or collimate light using a series of concentric grooves rather than a thick curved surface. At Band Optics, Fresnel lenses are produced under a fully customized, B2B-oriented custom optics wholesale model, supporting OEM and industrial clients with flexible designs and stable long-term supply. Instead of retail inventory, all Fresnel lenses are manufactured to order based on technical requirements defined during engineering review.
Compared with traditional lenses, Fresnel lenses significantly reduce material usage and weight while maintaining effective optical power. This makes them ideal for large-aperture or space-constrained systems where efficiency, cost control, and integration flexibility are critical.
The stepped surface profile of Fresnel lenses replaces the bulk of a conventional curved lens. This design offers:
Substantial weight reduction
Lower material cost for large diameters
Easier mechanical integration
Improved feasibility for portable or embedded systems
Fresnel lenses can be optimized for focusing, collimation, or beam shaping. Groove pitch, focal length, and aperture size can be customized to match system-level requirements. Through precision tooling and molding or machining processes, Band Optics ensures consistent optical performance across volume production for custom optics wholesale programs.
Fresnel lenses can be produced using a range of optical materials depending on application needs:
Optical-grade PMMA
Polycarbonate (PC)
Optical glass (for high-temperature or high-stability use)
Infrared-compatible polymers (upon request)
Material selection is guided by wavelength range, environmental exposure, and mechanical constraints.
Depending on design complexity and volume, manufacturing methods may include:
Precision injection molding
CNC machining
Diamond turning
Custom tooling development
