Photographers hold it in front of the lens to add rainbow flares and light effects to their shots.\u003c\/p\u003e\u003cp\u003eCoitak uses solid, clear K9 glass with high light transmittance, so the colors come through bright. At 1.2 inches per side, the prism is a great size for introducing refraction and dispersion.\u003c\/p\u003e\u003ch2\u003eCare and storage\u003c\/h2\u003e\u003cp\u003eWipe fingerprints off each face with the included microfiber cloth before you start. Keep the prism in its gift box between sessions to protect the glass. Set it on a stable surface during experiments so it cannot roll off the table. The boxed set also makes a thoughtful gift for a rainbow fan or a budding scientist.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"\/collections\/toys-games-for-babies-kids\"\u003escience toys and kids' gifts\u003c\/a\u003e at Big Frenchies.\u003c\/p\u003e","brand":"DS-AMZ","offers":[{"title":"Default Title","offer_id":50689985151216,"sku":"AMZ-B08M38XL6S","price":24.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0434\/7985\/9361\/files\/61YYHQlYPZL._AC_SL1500.jpg?v=1793243587","url":"https:\/\/www.bigfrenchies.com\/products\/coitak-6-inch-optical-glass-triangular-prism-b08m38xl6s","provider":"BIG FRENCHIES","version":"1.0","type":"link"}
