3 Description

The DLP301S digital micromirror device (DMD) is

a digitally controlled micro-opto-electromechanical

system (MOEMS) spatial light modulator (SLM).

When coupled to an appropriate optical system, the

DMD displays a very crisp and high quality image.

This DMD is a component of the chipset comprising

the DLP301S DMD, DLPC1438 3D Print controller,

and DLPA200x/DLPA300x PMIC/LED driver. The

compact physical size of this DMD coupled with

the controller and the PMIC/LED driver provides a

complete system solution that enables high output

optical engines for fast, high resolution, reliable DLP

3D printers.
