300mm PMMA Fresnel Lens Solar Concentrator 3x

300mm Fresnel Lens for Solar Concentration & Clear Magnification

This 300mm round PMMA Fresnel lens is designed for accurate light concentration and consistent optical performance in solar and inspection applications. With a large 300mm diameter and carefully engineered Fresnel grooves, it concentrates sunlight or artificial light into a defined focal area, or works as a large-area magnifier for viewing, testing and demonstration tasks.

Manufactured from optical-grade PMMA (acrylic), the lens offers high light transmission of around 92% for bright, clear images and efficient solar concentration. It supports multiple focal length options, including 120mm, 220mm, 360mm, 400mm and 2000mm, allowing you to select the appropriate working distance and spot size for different setups. The 3x magnification factor makes it suitable for enlarging text, components, patterns and surfaces over a broad viewing area. With a thickness of approximately 2mm, it remains lightweight and easy to mount in frames, stands or custom housings. Typical uses include solar concentrators, plane magnifiers, DIY and educational solar projects, flashlight and stage lighting optics, and general optical experiments where a wide aperture lens is required.

Why It's a Smart Choice

• Large 300mm diameter captures a wide light area for effective solar concentration and large-field magnification.
• High-transmittance PMMA construction delivers clear, bright images while remaining lightweight and impact-resistant.
• Multiple focal length options and 3x magnification provide flexibility for solar, educational, inspection and lighting applications.
