E-Series 1920 x 1200 SLM

There are 3 variations in the standard SLM series, each varying in calibration wavelength and response time, for more information or guidance please contact our experts.

The new 1920 x 1200 E-Series Liquid Crystal on Silicon (LC0S) SLM.  Don’t let the name fool you; with improved specifications over our previous model, it is anything but entry-level. It is, however, economical and ideally suited for educational labs with a limited budget.  Liquid Crystal on Silicon (LCoS) Spatial Light Modulators (SLMs) are uniquely designed for pure phase applications and incorporate analogue data addressing with high refresh rates. This combination provides users with the fastest response times and highest phase stabilities commercially available.  Meadowlark offers both transmissive and reflective SLMs in either one- or two-dimensions.  Phase-only SLMs can also be used for amplitude-only or a combination of both.

Key features

  • Entry-Level
  • 1920 x 1200 Resolution
  • Pure Analogue Phase Control
  • High Phase Stability – as low as 0.025%
  • 60 Hz HDMI Controller with Output Trigger

High Phase Stability

Meadowlark Optics is known for having the fastest SLMs with the least amount of phase ripple on the market. Our backplanes are custom designed with high refresh rates and direct analogue drive schemes, resulting in phase ripple for standard products ranging between 0.10 – 0.30%. For customers who require even better performance, customisation is possible with phase ripple as low as 0.025% (0.0008 π radians). Phase ripple is quantified by measuring the variation in the intensity of the 1 st order diffracted spot as compared to the mean intensity while writing a blazed phase grating to the SLM.


Meadowlark Optics’ SLMs are supplied with a Graphical User Interface and software development kits that support LabVIEW, Matlab, Python and C++. The software allows the user to generate images, to correct aberrations, calibrate the global and/or regional optical response over ‘n’ waves of modulation, to sequence at a user defined frame rate, and to monitor the SLM temperature.

Software Features
  • Output Trigger
  • Image Generation
  • Automated Sequencing
  • Wavefront Calibration
  • Global and Regional Look Up Tables
