Beam Shifting Devices

Optotune’s XPR®-25 is an Extended Pixel Resolution 4-position Actuator. With a clear aperture of about 25mm it is designed for use with Texas Instrument’s 0.47” DMD ECD and Pico chipset.

Main features:

  • High angular position accuracy of typically +/-8%
  • Fast transition times of typically 1.2 to 1.3ms
  • Low acoustic noise of typically 21dBA
  • Fully pre-calibrated at 50 & 60Hz for temperatures up to 75°C

Working principle:

The pixel shifting principle is that of tilting a glass window. The XPR®-25 tilts a glass window in two axes to reach four distinct positions. As a result each pixel is projected to four locations. The result is a high-quality 4K display.

Beyond the use case at 50 or 60Hz in projectors, the XPR®-25 can also be used in DC mode or calibrated to perform different shifting patterns. Further applications include 3D printing (resolution increase and/or smoothing), cameras (super-resolution imaging) and metrology
