Spatial Light Modulators

As their name would indicate, spatial light modulators modulate light according to a fixed pixel, or spatial, pattern. Meadowlark Optics manufactures and sells three different variations of these modulators to address a variety of photonics-based applications.

The XY Series of Spatial Light Modulators are designed for typical optical laboratory environments. They feature:

  • 256 x 256 or 512 x 512
  • Phase, Amplitude or Combined
  • High Speed Phase Modulation (up to 500 Hz)
  • High Efficiency (up to 95%)
  • Low Phase Ripple
  • Minimal Crosstalk
  • High Optical Resolution

The linear series of spatial light modulators are ideal for beam steering and printing applications. They use standard Liquid Crystal (LC) on CMOS technology and feature:

  • 1 x 12,288 Pixels
  • High optical efficiency
  • No mechanical motion
  • High speed phase control
  • Safe, low voltage operation
  • User-friendly graphical interface

Lastly, Meadowlark Optics has begun offering engineering evaluation samples of their polarization independent liquid crystal on silicon spatial light modulators (LCoS SLM). They’re well suited for flexible-grid fiber telecommunication networks, enhanced microscopy, and high-resolution adaptive optics. They feature:

  • 256 x 256 Format
  • Doubles Your Efficiency
  • Analog Phase Operation
  • Efficiently Diffracts Randomly Polarized Light
  • Insensitive to Polarization variation
  • Diffracts LED light
  • Works up to 1550 nm
