3 Description

Featuring over 8.9 million micromirrors, the highresolution

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 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.
