Mid Spatial Frequency (MSF) Error Surface Smoothing
Eliminating errors is a central tenet of optical innovation. Small tool polishers tend to leave residual mid-spatial frequency (MSF) errors on surfaces which can lead to blurring or even scattering of light. Even small scattering angles can be detrimental to optical performance and needs a solution.
The Challenge
Small tool polishers leave residual MSF errors on surfaces that in an imaging system can create blur or small angles of scatter.
Solution Delivered
We deliver an iterative smoothing process to reduce MSF errors and are currently developing a robotic machine learning solution that can be used on freeform surfaces.
