3 Description

Featuring over 8.9 million micromirrors, the highresolution

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.
