Now, with the \u003cstrong\u003ecamera + lens\u003c\/strong\u003e \u003cem\u003e(ideal: 2.8 \/ focal length 24 mm - 35 mm)\u003c\/em\u003e, the motif in the glass sphere can be focused with a shallow depth of field, while still allowing the background to artistically flow into the image.\u003c\/p\u003e\n\u003cp\u003eFor all of this to be possible, the \u003cstrong\u003eglass must be manufactured with the highest quality and without inclusions\u003c\/strong\u003e. This is ensured by our special \u003cstrong\u003equality controls and the transparent manufacturing process\u003c\/strong\u003e, in which the spheres are checked multiple times during production for material defects, inclusions, and cracks.\u003c\/p\u003e\n\u003cp\u003eThe glass is first melted into a long rectangle. The \u003cstrong\u003ehigh temperatures make the glass soft and easily formable\u003c\/strong\u003e. Subsequently, individual cuboids are cut from this glass rectangle. Due to the previous melting process, these cuboids are still easily formable and are now placed in a hydraulic press and shaped into their round form. Now it's time for \u003cstrong\u003ecooling to room temperature of approx. 20 degrees Celsius\u003c\/strong\u003e. To avoid imperfections such as surface irregularities and bubbles, the glass spheres are cooled down very slowly and temporarily stored. \u003cstrong\u003eAfter cooling\u003c\/strong\u003e, the \u003cstrong\u003efirst inspection of the raw material for cracks \u0026 inclusions\u003c\/strong\u003e takes place. All solid glass spheres that are of impeccable quality then go for \u003cstrong\u003egrinding and polishing\u003c\/strong\u003e \u003cstrong\u003euntil they have received their absolutely flawless and round shape\u003c\/strong\u003e. Then, the \u003cstrong\u003enext check for air inclusions and other defects\u003c\/strong\u003e takes place. If a defect is found here, the glass sphere is sorted out. Now, the \u003cstrong\u003efinal fine grinding\u003c\/strong\u003e is carried out with a \u003cstrong\u003ehigh-speed polishing machine\u003c\/strong\u003e. After a certain time, the spheres are completely transparent and have a perfect surface quality. Now, the final quality control follows – \u003cstrong\u003euntil the perfect end result of each glass sphere\u003c\/strong\u003e. Only in this way can it be ensured that the glass sphere does not negatively affect light refraction later, or that inclusions and scratches appear as disturbing elements in your mirrored motif.\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg height=\"1024x1024\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0273\/9113\/1725\/files\/22694_Lensball-110mm_Purple_Louvre_Paris_1024x1024.jpg?v=1598971581\" style=\"float: none;\" width=\"1024x1024\"\u003e\u003c\/div\u003e\n\u003cp\u003e\u003ca href=\"\/en\/products\/lensball-halterung-22924\" title=\"Produktinformation Lensball-Halterung\"\u003e\u003cimg alt=\"Lensball holder for lensballs up to 90 mm in size\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0273\/9113\/1725\/files\/22924_Lensball-Halter_06.jpg?v=1651732156\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eSafety notice!
