This fully glue-less 3D wooden puzzle kit is a working scope that lets you magnify tiny objects at 4x, 10x, and up to 40x using multiple lenses mounted on a revolving nosepiece. Turn on the LED light, place samples on the slide, and use the knob to adjust the lens barrel for sharper focus. Each full turn produces an audible click and raises the lens barrel by 4.5mm, made possible by its precisely engineered worm and worm-gear system. Improve contrast and sharpen details with green and blue switchable filters. Powered by 2 AAA batteries, this interactive assembly turns curiosity into an enjoyable scientific adventure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"ROKR","offers":[{"title":"Default Title","offer_id":53358790869357,"sku":"ST005","price":50.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/2765\/1230\/files\/14_2bb2feb4-d7f4-4af8-b602-c59f4f9a52ac.jpg?v=1779353001","url":"https:\/\/www.robotimeonline.com\/en-de\/products\/rokr-microscope-wooden-3d-puzzle-st005","provider":"Robotime Online","version":"1.0","type":"link"}
