Product Introduction

Description:

MDC is a motorized device which changes beam pergence from approximately -2 mrad (converging) to +4 mrad (perging). As an addon to 2D galvo scanners this device upgrades automated 2D fabrication setup to 3D. It is achieved by changing focal point position along z-axis when adjusting beam pergence. MDC can control working distance and focus beam diameter in real time. Device is lighter in weight and smaller in dimensions compared to other solutions in the market. Due to simplified design it is a cost saving and user-friendly device.
