A number of original prisms from Leica Geosystems have a special coating on the reflective surfaces – the anti-reflective coating – and a copper coating on the reverse side. Without these, the range of distance measuring, ATR and PowerSearch would be reduced by up to 30%. The workmanship and the durability of the copper coating are decisive for a long life. The glass dimensions, the position in the holder and the areal orientation are important for measuring accuracy.\u003c\/p\u003e \u003cp\u003eLeica Geosystems prisms are manufactured from glass of the highest quality and furnished with optical coatings so that even under the most extreme environmental conditions, a long lifetime and maximum range of the highest accuracy can be achieved.\u003c\/p\u003e","brand":"Leica GeoSystems","offers":[{"title":"Default Title","offer_id":61970036818290,"sku":"ES2188","price":320.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/3234\/1874\/files\/1372_main.jpg?v=1782229008","url":"https:\/\/allenprecision.com\/products\/641618-gpr111-prism-assembly","provider":"allenprecision","version":"1.0","type":"link"}
