Core Concepts
This paper presents a novel catadioptric relay system optimized for high-resolution, high-contrast imaging in maskless array synthesis (MAS) of biomolecules, addressing the limitations of previous Offner relay systems for large-format DMDs and enabling more efficient and accurate synthesis of DNA, RNA, and other oligomers.

The study aimed to develop an improved optical relay system for maskless array synthesis (MAS) of biomolecules, specifically designed to overcome the limitations of existing Offner relay systems when used with large-format digital micromirror devices (DMDs). The goal was to achieve higher resolution and contrast imaging for more efficient and accurate synthesis of DNA, RNA, and other oligomers.
