infocus #69 March 2023 Investigating the liquid Characterising the surface quality of 3D printed optical elements using interference reflection microscopy

Optical microscopy has used the same manufacturing methods for milling and sanding glass elements to produce high-quality optics for over a century. Recent developments in 3D printing have opened the possibility of printing optical components, but the surface quality of these 3D prints remains unknown.
