Description

Featuring over 8.9 million micromirrors, the high-resolution DLP991UUV digital micromirror device (DMD) is a spatial light modulator (SLM) that modulates the amplitude, direction, and/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 DLP991UUV DMD and the DLPC964 controller make the device exceptional for high-speed continuous data streaming for direct imaging (LDI) applications. The DMD enables large 3D Print build sizes and ultra-fine resolutions for a variety of 3D printing applications. The high resolution provides a direct benefit to the scanning of larger objects in 3D machine vision applications.
