📝 Product Details
Pocket Lighthouse – Miniature Lighthouse Optics for Your Smartphone
Inspired by Augustin Fresnel’s historic lighthouse lenses, this attachment creates a compact lighthouse-style beam.
How It Works: Flat sheet Fresnel lenses need ~120 mm focal distance and cannot focus a smartphone LED. This lens uses deeper prism geometry with a working distance of ~21 mm for efficient beam formation.
Not an Imaging Lens: Designed for illumination, not magnifying text or focusing sunlight.
How to Align: Center the lens over the LED. Use the included 40 mm disk for flexibility. Raised cases may interfere.
Lightweight PET Construction: Recyclable PET, only 35 g. Great for tours, STEM, and emergency signaling.
Educational + Novelty Function: A souvenir that doubles as a STEM teaching aid demonstrating real lighthouse optics.
LIGHTHOUSE-INSPIRED OPTICS: Miniature version of multi-stage Fresnel principles pioneered by Augustin Fresnel.
COMPACT SHORT-FOCUS DESIGN (~21 mm): Works close to the LED, unlike flat Fresnel sheets requiring ~120 mm.
ILLUMINATION LENS, NOT A MAGNIFIER: Designed for beam shaping, not reading or solar focusing.
ALIGNMENT REQUIRED: Center lens over LED. 40 mm metal disk gives flexible placement. Raised cases may interfere.
LIGHTWEIGHT RECYCLABLE PET: Only 35 g. Ideal for lighthouse tours, STEM demonstrations, and signaling.
NOVELTY + EDUCATIONAL TOOL: Originally created for lighthouse gift shops and STEM learning.
