Square Fresnel Lens 30x30 40x40 50x50 100x100mm PMMA Acrylic DIY Projector Solar Condenser Magnifying Glass(30x30mm-FL28mm)

Precision molded PMMA acrylic Fresnel lens with 92% light transmission, offering clear magnification and efficient light condensation for DIY projectors, solar concentrators and optical experiments. Available in different sizes (30x30mm, 40x40mm, 50x50mm, 100x100mm) with clearly marked focal lengths, allowing flexible integration into custom lighting, stage lights, flashlights and fishing lamps. The threaded surface structure (0.3mm or 0.5mm pitch) helps reduce glare and improve light scattering, while the 2mm flat thickness ensures easy mounting in various frames or housings. The durable acrylic material withstands temperatures from -40°F to +176°F, making it suitable for both indoor and outdoor applications including solar collection and heat exposed environments. Ideal for teaching physics experiments, optical research and product prototyping, this one-piece lens delivers consistent performance and reliable optical characteristics for hobbyists and engineers.
