3D DMD mechanical geometry
Data sheet
DLP301S
- 0.3-Inch (7.93-mm) diagonal micromirror array
- 1280 × 720 array of aluminum micrometer-sized mirrors, in an orthogonal layout
- 3.6 Megapixels, 2560 × 1440 pixels on the resin
- 5.4-micron micromirror pitch
- ±17° micromirror tilt (relative to flat surface)
- Side illumination for optimal efficiency and optical engine size
- Polarization independent aluminum micromirror surface
- 8-Bit SubLVDS input data bus
- Dedicated DLPC1438 3D print controller and DLPA200x or DLPA300x PMIC/LED driver for reliable operation
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.
