Solar Thermal Systems Fresnel Lens 900mm Focal Length Φ360mm Large-Aperture Solar Concentration Optic


This Solar Thermal Systems Fresnel Lens is designed for optical applications that require controlled solar radiation concentration and efficient collection of incident sunlight. With a 900mm focal length and 0.5mm groove pitch, the lens provides a defined Fresnel optical structure for directing incoming solar energy toward a designated focal region.

The lens can be manufactured within a maximum diameter of Φ360mm, providing a relatively large optical aperture for solar concentration assemblies and experimental thermal-energy systems.

Its Fresnel architecture offers a lightweight alternative to conventional thick concentrating lenses, making it suitable for optical systems where aperture size, focal geometry, and component weight need to be considered together.

Customer also Ask

What is a Fresnel lens used for in solar thermal systems?
A Fresnel lens can redirect and concentrate incoming solar radiation toward a defined focal region, where the concentrated energy can be used by a downstream thermal or experimental system.

What does the 900mm focal length mean in a solar Fresnel lens?
The 900mm focal length describes the lens's principal concentrating geometry and serves as an important reference when positioning the lens relative to the target or receiver.

What is the advantage of a large-diameter Fresnel lens for solar concentration?
A larger optical aperture can collect sunlight over a greater area, making aperture size an important consideration when designing solar concentration systems.

Can this solar Fresnel lens be customized?
Yes. The lens can be manufactured within a maximum diameter of Φ360mm, with the final optical configuration evaluated according to the collector design and application requirements.
