Zygo Corporation (a division of AMETEK)announced the release of Compass 2, its latest optical profiler with Diamond Turning Machine (DTM) optimization and freeform surface metrology capability. Unlike comparable solutions, mold pins remain on their manufacturing fixture during metrology―shortening the time to data processing and minimizing uncertainty from remounting and re-aligning the sample. With new interface improvements, the Compass 2 now delivers 3x better form deviation performance than the original Compass.
在过去的十年中，Compass和Compass RT计量系统为非接触，自动3D表面计量学和生产过程控制了离散的微镜头和模具的标准汽车视觉系统。
Zygo产品经理Eric Felkel说：“ Compass 2设计用于分析旋转对称的球形和无球，几何截断和自由形式表面。它可以测量离散的镜头和注入成型引脚；该仪器是专门针对使用此过程的一系列新功能来满足制造商需求的。”
“Beyond just DTM integration, the Compass 2 has the necessary XYZ precision to report nm-level roughness data that includes automatic generation of high frequency texture and tooling mark surface maps. A unique feature is the ability to click at a point on a data map and the system quickly navigates to that specific location on the sample for a more detailed inspection.”
Diamond Turning Machine (DTM) tool path correction support: The data obtained by the Compass 2 can now be directly used to optimize a DTM toolpath by automatically exporting 3D prescription deviation data for use with multiple DTM platforms as well as multi-platform software such as DIFFSYS™.
DTM tool setup support: Compass 2 supports DTM Tool setup with tool offset and tool radius measurement for spheres and aspheres and can report predicted surface deviation after offset and radius correction.
DTM固定装置支持：新的Compass 2样品接口包括一个标准真空CHUCK固定装置，该固定装置支持DTM Chuck/Jigs，直径为10-155毫米，重量高达0.8 kg。在计量学期间，霉菌销可以保留在制造固定装置上，从而缩短数据的时间，并最大程度地减少对样品进行重新安装和重新调整的不确定性 - 尤其是在进行刀具路径校正测量时。
自由形式支持：随着移动设备摄像机的设计的发展，越来越多地使用了自由式表面。Freeforms的设计几乎没有对称性，这使它们在大多数计量仪器中都具有挑战性。Compass 2现在在其软件包中包括自由形和截断的表面分析。Compass 2使用其在测量过程中跟踪表面以捕获自由形式表面的能力。该平台将以与完整的3D测量区域的传统沥青相同的方式计算该轨道表面的偏差到自由形式的光学处方。
一个全新的平台：Compass 2是从头开始设计的，重点是强大的计量学和高信心。这起着使用高度准确的计量工具在过程中而不是内置的使用，并且通常在工厂地板上极具动态和挑战性的区域工作。改进包括新的：
•具有10倍更好的地震隔离的隔离平台
•高度优化的支持结构
•外壳和用户站完全与仪器解耦
•分离的电子机架隔离噪声源与计量学
外壳和设备架还可以更轻松地安装，更轻松的维修，更容易的测量零件访问以及降低机器的振动和湍流。
Legacy metrology tools can be challenged with measuring larger slope angles, can be time-consuming, have a small measurement range, and have a small working distance. The Compass 2 addresses these challenges by using optimized non-contact, three-dimensional coherence scanning interferometry with field stitching―making it the platform of choice for system-critical micro-optical surfaces.
