<p style="font-size:15px; font-family:'Open Sans', Arial, sans-serif !important;"><p>This webinar will delve into the definition and evaluation of topography measurement noise in optical instruments, focusing on the importance of low noise levels for accurate surface topography measurements. We will explore the ISO standards for measurement noise, experimental methods for quantifying noise, and the distinction between instrument noise and measurement noise. Practical examples, including phase-shifting interferometry and measurements of super-polished and rough surfaces, will illustrate key concepts. Attendees will gain insights into strategies for reducing noise and optimizing measurement tasks, ensuring confidence in their metrology results.</p>
