Powerful New Software Platform The MicroXAM-800 features a new software platform with an innovative, yet simple interface. The software has been designed with ease of use in mind. SMART acquire is a simplified acquisition mode that makes intelligent control setting decisions based-on a single user input – the vertical scan range. The remaining scanning control adjustments follow automatically. This enables users to rapidly obtain good results with minimal training, improving time to results, and simplifying the user experience. ZSI acquire is a powerful acquisition mode that allows multiple...

Theory of Operation 3D optical profiling uses white light interferometry (WLI), to generate high-resolution height maps. This is also known as coherence scanning interferometry (CSI). The principle of operation is based on splitting a beam of incoherent light into two beams, redirecting one to reflect from a reference mirror, and the other to reflect from the sample surface. After reflecting, the beams travel to the CCD camera, where each pixel acts as an independent light detector. The light recombines coherently when the path distances for the two beams are matched. The resulting...
