Select Mid Spatial Frequency (MSF) Error Surface Smoothing
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.

Smoothing Mid-spatial Frequency (MSF) Errors on Freeform Optics with an Algorithm-based Robotic Platform Utilizing Deflectometry Input
Optimax has developed the HERMES (High End Robotic MSF Elimination System) a robotic platform that uses a machine learning algorithm to smooth parts. Preliminary research indicated promising results, but the process had not yet been compared to the “gold standard” of human smoothing.

Optical designers choose Optimax for our high-precision freeform optics, which reduce system complexity with smaller, lighter profiles. As a leading producer, we combine optimal grinding and smoothing technologies to fabricate precise components with minimal positional and mid-spatial frequency errors. This expertise allows us to tackle challenging projects and produce high-precision freeforms for UV, Visible, and IR applications using proprietary low-scatter techniques.
