Key Takeaways Cylindrical lens performance depends on surface profile accuracy, curvature radius precision, and transmitted wavefront quality. Utilizing a mix of contact profilometry for high-roughness parts and non-contact ZYGO interferometry for ultra-high-precision (PV 0.05λ) ensures compliance with ISO 10110-5 standards. Beyond geometry, wavefront sensing and MTF testing are critical to verifying imaging resolution and contrast. […]
Key Takeaways: Surface roughness, surface texture, surface finish, surface roughness measurement, profilometer, Ra value, Rq roughness, and high-precision optics are essential for controlling optical performance. Nanometer-scale roughness causes light scattering, distortion, and lowers laser damage thresholds. Surface roughness results from manufacturing methods, material structure, and environmental effects. Tools like profilometers and AFM provide accurate surface […]
