The fold-out body protects the lens and acts as a focusing jig: open until the specimen appears sharp (typically 8–12mm working distance at 30×). Black chrome finish reduces stray light reflections.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e30× magnification; 21mm achromatic triplet lens — flat field, colour-correct\u003c\/li\u003e\n\u003cli\u003eBlack chrome aluminum body; fold-out protective housing\u003c\/li\u003e\n\u003cli\u003eWorking distance ~10mm; resolves features as small as 0.05mm\u003c\/li\u003e\n\u003cli\u003eIncludes leather case and neck lanyard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eEvery purchase directly funds independent physics research at the Golden Physics Project.\u003c\/em\u003e\u003c\/p\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54144338854180,"sku":"GPP-OPT-LOUPE30X","price":49.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/photo-1516035069371-29a1b244cc32_fdfb589f-aa90-4875-8c73-aa4e930f19ad.jpg?v=1780368572","url":"https:\/\/shop.goldenphysics.org\/products\/jewellers-loupe-30-triplet-achromatic-black-chrome-21mm-lens","provider":"Golden Physics Project","version":"1.0","type":"link"}
