Em estudos onde a interface das caracter\u00edsticas da superf\u00edcie, padr\u00f5es, formas, etc., est\u00e3o sendo avaliados para orienta\u00e7\u00e3o, ser\u00e1 \u00fatil identificar rapidamente \u00e1reas de interesse em todo o perfil de medi\u00e7\u00e3o. Ao segmentar uma superf\u00edcie em \u00e1reas significativas, o usu\u00e1rio pode avaliar rapidamente limites, picos, po\u00e7os, \u00e1reas, volumes e muitos outros para entender seu papel funcional em todo o perfil de superf\u00edcie em estudo. Por exemplo, como a imagem de um limite de gr\u00e3os de metais, a import\u00e2ncia da an\u00e1lise \u00e9 a interface de muitas estruturas e sua orienta\u00e7\u00e3o geral. Atrav\u00e9s da compreens\u00e3o de cada \u00e1rea de interesse podem ser identificados defeitos e ou anormalidades dentro da \u00e1rea geral. Embora as imagens de limite de gr\u00e3o sejam tipicamente estudadas em uma faixa que ultrapassa a capacidade do Profil\u00f4metro e seja apenas uma an\u00e1lise de imagem 2D, \u00e9 uma refer\u00eancia \u00fatil para ilustrar o conceito do que ser\u00e1 mostrado aqui em uma escala maior, juntamente com as vantagens da medi\u00e7\u00e3o de superf\u00edcie 3D.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Ao contr\u00e1rio de outras t\u00e9cnicas, como sondas de toque ou interferometria, o Perfil\u00f4metro sem contato 3D<\/a>, usando cromatismo axial, pode medir praticamente qualquer superf\u00edcie, os tamanhos das amostras podem variar amplamente devido ao preparo aberto e n\u00e3o h\u00e1 necessidade de prepara\u00e7\u00e3o da amostra. A faixa nano a macro \u00e9 obtida durante a medi\u00e7\u00e3o do perfil da superf\u00edcie com influ\u00eancia zero da refletividade ou absor\u00e7\u00e3o da amostra, possui capacidade avan\u00e7ada para medir \u00e2ngulos de superf\u00edcie elevados e n\u00e3o h\u00e1 manipula\u00e7\u00e3o de resultados por software. Me\u00e7a facilmente qualquer material: transparente, opaco, especular, difusivo, polido, \u00e1spero, etc. A t\u00e9cnica do perfil\u00f4metro sem contato fornece uma capacidade ideal, ampla e f\u00e1cil de usar para maximizar estudos de superf\u00edcie quando a an\u00e1lise de limites de superf\u00edcie for necess\u00e1ria; juntamente com os benef\u00edcios da capacidade combinada de 2D e 3D.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
