Featuring over 8.9 million micromirrors, the high-resolution DLP991U digital micromirror device (DMD) is a spatial light modulator (SLM) that modulates the amplitude, direction, or phase of incoming light. This advanced light control technology has numerous applications in the industrial, medical, and consumer markets. The streaming nature of the DLP991U and its DLPC964 controller make it ideally suited for exceptionally high-speed continuous data streaming for direct imaging (LDI) applications. The DMD enables large 3D print build sizes and ultra-fine resolutions for various 3D printing applications. The high resolution provides a direct benefit to the scanning of larger objects in 3D machine vision applications.
