Meadowlark Optics’ Liquid Crystal on Silicon (LCoS) Spatial Light Modulators (SLMs) are uniquely designed for pure phase applications and incorporate analog data addressing with high refresh rates (1400 Hz). This combination provides users with the fastest response times with high phase stability. The 1024 x 1024 SLM is good for applications requiring high speed, high diffraction efficiency, low phase ripple and high-power lasers.

High Phase Stability – Making an LCOS SLM faster usually means the phase stability is worse. However, we’ve combined our traditional analog drive scheme with new proprietary technologies to suppress phase instabilities to 0.05% to 2.0% without compromising speed. Phase ripple is quantified by measuring the variation in intensity of the 1st order diffracted spot as compared to the mean intensity while writing a blazed phase grating to the SLM. Since phase stability varies as a function of pixel voltage, this measurement approach is an average and does not represent all scenarios. If your application requires extremely low phase ripple, please contact a Meadowlark Solutions Engineer for more information on the 19×12 SLM.

1024 x 1024 Spatial Light Modulator

High Speed with High Phase Stability – Great care was taken in the design of the 1024 x 1024 silicon backplane to enable high speed operation while simultaneously maximizing phase stability. The 1024 x 1024 SLM is incredibly fast with liquid crystal response times ranging from 0.6 to 8 ms (wavelength dependent) for a full wave of modulation. In our ultra-high speed model customers can control the temperature set point to find the perfect balance between switching speed and phase stability.
