									<p data-start="836" data-end="1458">The ability to accurately characterize tooth surfaces, including micro-roughness and 3D surface topography at the nanometer scale, enables advanced research and applications in orthodontics and dental materials science. Non-contact optical profilometry provides a precise method for measuring dental surface roughness and analyzing tooth surface morphology without damaging delicate structures. These measurements support the development of composite dental materials that replicate the natural surface roughness of enamel, as well as the design and fabrication of patient-specific dental casts and restorative components.</p><p data-start="1460" data-end="1982">Low surface roughness plays a primary role in limiting bacterial adhesion and plaque formation, thereby reducing the risk of cavities. An increase in average roughness (Ra) above 2 µm leads to a steep increase in biofilm formation in vivo.¹ An Ra of 0.2 µm is considered the threshold value below which no further reduction in bacterial adhesion can be expected.²</p><p data-start="1984" data-end="2182">Reconstruction of the tooth’s 3D surface topography enables the fabrication of dental casts, which are essential for accurate diagnosis, treatment planning, and the fabrication of dental appliances.</p>								</div>

Chromatic Light technology offers significant advantages over classical touch probe techniques. It acquires data points from deep crevices and complex geometries without introducing measurement errors or artifacts caused by local plastic deformation and without requiring extensive data manipulation.</p><p data-start="715" data-end="1135">Compared to focus variation systems, single-point optical sensing provides superior lateral and height accuracy, with X/Y resolution below 0.5 µm, maximum vertical resolution of 1.9 nm, and the ability to measure surface angles up to 87°.

					<description><![CDATA[<p>SHOT PEENED SURFACE ANALYSIS USING 3D NON-CONTACT PROFILOMETER Prepared by CRAIG LEISING INTRODUCTION Shot peening is a process in which a substrate is bombarded with spherical metal, glass, or ceramic beads—commonly referred to as &#8220;shot&#8221;—at a force intended to induce plasticity on the surface. Analyzing the characteristics before and after peening provides crucial insights for [&#8230;]</p>

									<p>图 2、图 3 和图 4 分别显示了代表性时间的假色视图、三维视图和干燥油漆形貌的二维剖面图。图像中的假色有助于检测不易辨认的特征。不同的颜色代表样品表面不同区域的高度变化。三维视图为用户提供了从不同角度观察油漆表面的理想工具。在测试的前 30 分钟，油漆表面的假色逐渐从暖色调变为冷色调，表明在此期间高度随时间逐渐降低。这一过程会减慢，正如在 30 分钟和 60 分钟时比较油漆的颜色变化轻微所显示的那样。</p><p>样品的平均高度和粗糙度 Sa 值与涂料干燥时间的函数关系如图 5 所示。 表 1 列出了干燥 0、30 和 60 分钟后涂料的完整粗糙度分析。可以看出，在干燥时间的前 30 分钟内，油漆表面的平均高度从 471 微米迅速下降到 329 微米。溶剂汽化的同时，表面纹理也随之形成，导致粗糙度 Sa 值从 7.19 微米增加到 22.6 微米。此后，涂料干燥过程减慢，导致样品高度和 Sa 值逐渐下降，在 60 分钟时分别降至 317 微米和 19.6 微米。</p><p>这项研究强调了 NANOVEA 3D 非接触式轮廓仪在实时监测干燥涂料的 3D 表面变化方面的能力，为了解涂料干燥过程提供了宝贵的资料。通过在不接触样品的情况下测量表面形态，轮廓仪避免了滑动测针等接触式技术可能对未干涂料造成的形状改变。这种非接触式方法可确保对干燥涂料表面形态进行准确可靠的分析。</p>								</div>

<p>在这一应用中，我们展示了 NANOVEA ST500 3D 非接触式轮廓仪在监测干燥过程中涂料表面形态演变方面的能力。高速光学线传感器可产生一条由 192 个光点组成的线，同时扫描样品表面，从而在确保无与伦比的精确度的同时提高了研究的时间效率。</p>
<p>采集软件的宏功能可对三维表面形态进行编程自动测量，特别适用于在特定目标时间间隔内进行多次扫描的长期测量。它大大减少了时间、精力和用户出错的可能性。在涂料干燥的过程中，表面形态的渐进变化会被持续监测和实时记录，为了解涂料的干燥机理提供有价值的信息。</p>
<p>此处显示的数据仅代表分析软件中可用计算的一小部分。NANOVEA 轮廓仪几乎能够测量任何表面，无论是透明表面、暗表面、反射表面还是不透明表面。</p></div></div></div>

									<p>断口分析是对断裂表面特征的研究，历史上一直通过显微镜或 SEM 进行研究。根据特征的大小，选择显微镜（宏观特征）或SEM（纳米和微观特征）进行表面分析。两者最终都可以识别断裂机制类型。尽管有效，但显微镜具有明显的局限性，并且在大多数情况下，除了原子级分析之外，SEM 对于断裂表面测量来说是不切实际的，并且缺乏更广泛的使用能力。随着光学测量技术的进步，NANOVEA <a href="https://nanovea.com/profilometers/">3D 非接触式轮廓仪</a> 现在被认为是首选仪器，能够通过宏观尺度 2D 和 3D 表面测量提供纳米级测量</p>								</div>

									<p>在这个应用中，我们展示了NANOVEA ST400 3D非接触式轮廓仪是如何精确表征断裂表面的全部地形（纳米、微观和宏观特征）的。从三维区域中，可以清楚地识别出表面，并且可以快速提取子区域或剖面/横截面，并通过无尽的表面计算列表进行分析。亚纳米级的表面特征可以通过集成的AFM模块进一步分析。</p><p>此外，NANOVEA还在其Profilometer阵容中加入了一个便携式版本，这对于不可移动的裂缝表面现场研究来说尤其重要。有了这些广泛的表面测量能力，使用一台仪器进行断裂表面分析从未如此简单和方便。</p>								</div>

					<description><![CDATA[<p>FIBERGLASS SURFACE TOPOGRAPHY USING 3D PROFILOMETRY Prepared by CRAIG LEISING INTRODUCTION Fiberglass is a material made from extremely fine fibers of glass. It is used as a reinforcing agent for many polymer products; the resulting composite material, properly known as fiber-reinforced polymer (FRP) or glass-reinforced plastic (GRP), is called &#8220;fiberglass&#8221; in popular usage.

									尽管玻璃纤维加固有许多用途，但在大多数应用中，尽可能地提高强度是至关重要的。玻璃纤维复合材料是目前强度与重量比最高的材料之一，在某些情况下，其强度比钢铁还要高。除了高强度外，拥有尽可能小的暴露表面面积也很重要。大面积的玻璃纤维表面会使结构更容易受到化学侵蚀，并可能导致材料膨胀。因此，表面检查对于质量控制生产至关重要。								</div>

									<p>摩擦和磨损对于皮带驱动的机器中的皮带来说是不可避免的。足够的摩擦确保有效的动力传输而不打滑，但过度的摩擦可能会迅速磨损皮带。不同类型的磨损，如疲劳、磨损和摩擦，都发生在皮带传动操作中。为了延长皮带的使用寿命，减少皮带维修和更换的成本和时间，可靠地评估皮带的磨损性能对于提高皮带寿命、生产效率和应用性能是可取的。准确测量皮带的摩擦系数和磨损率，有利于研发和皮带生产的质量控制。</p>								</div>

									<p>在这项研究中，我们展示了NANOVEA T2000摩擦仪在以良好的控制和定量方式评估皮带的摩擦系数和磨损率方面的能力。在皮带的使用性能中，表面纹理对皮带的摩擦和耐磨性起着关键作用。有纹理的皮带表现出稳定的摩擦系数约为0.5，并拥有较长的使用寿命，从而减少了工具维修或更换的时间和成本。相比之下，光滑皮带对钢球的过度摩擦会迅速磨损皮带。此外，皮带上的负载是影响其使用寿命的一个重要因素。过载会产生非常大的摩擦，导致皮带加速磨损。</p>
<p>NANOVEA T2000摩擦仪采用符合ISO和ASTM标准的旋转和线性模式，提供精确和可重复的磨损和摩擦测试，并在一个预集成的系统中提供可选的高温磨损、润滑和摩擦腐蚀模块。&nbsp;<span style="font-size: 16.8px;">NANOVEA的&nbsp;</span>无与伦比的产品系列是确定薄或厚、软或硬的涂层、薄膜和基材的全部摩擦学特性的理想解决方案。</p>								</div>

									<p>在这项应用中，我们展示了NANOVEA ST400三维轮廓仪如何精确地描述加工皮革的表面光洁度。在这项研究中，拥有测量表面粗糙度、窝点深度、窝点间距和窝点直径的能力，使我们能够量化两个样品的光洁度和质量之间的差异，这些差异通过目视检查可能并不明显。</p><p>总的来说，SAMPLE 1和SAMPLE 2之间的3D扫描的外观没有明显区别。然而，在统计分析中，这两个样品之间有明显的区别。与SAMPLE 2相比，SAMPLE 1含有更多直径较小、深度较大、窝点与窝点之间间距较小的窝点。</p><p>请注意，还可以进行更多的研究。特别感兴趣的领域可以通过集成AFM或显微镜模块进一步分析。NANOVEA 3D轮廓仪的速度范围从20毫米/秒到1米/秒，用于实验室或研究，以满足高速检测的需要；可以定制尺寸、速度、扫描能力、符合1级洁净室标准、索引传送带或用于在线或在线集成。</p>								</div>
