E-Series: Educational, Economical & Entry-level

Meadowlark Optics is pleased to introduce our latest E-Series Spatial Light
Modulator (SLM). Don’t let the name fool you; with improved specifications
over our previous model, it is anything but entry-level. It is, however, economicaland ideally suited for educational labs with a limited budget. Liquid Crystal on
Silicon (LCoS) Spatial Light Modulators (SLMs) are uniquely designed for purephase applications and incorporate analog data addressing with high refresh
rates. This combination provides users with the fastest response times andhighest phase stabilities commercially available.

Meadowlark offers bothtransmissive and reflective SLMs in either one- or two-dimensions. Phase-only
SLMs can also be used for amplitude-only or a combination of both.

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

SLM Features•••

custom designed with high refresh rates and direct analog drive schemes,

High resolution

resulting in phase ripple for standard products ranging between 0.10 – 0.30%.

High Phase StabilityFor customers who require even better performance, customization is possible
with phase ripple as low as 0.025% (0.0008 π radians). Phase ripple is quantified
by measuring the variation in intensity of the 1st order diffracted spot ascompared to the mean intensity while writing a blazed phase grating to the SLM.

the percentage of light measured in the 1storder when writing a linear repeating phaseramp to the SLM as compared to the light in the
0th order when no pattern is written to the SLM.
Diffraction efficiency varies as a function of thenumber of phase levels in the phase ramp. The

Software - 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, tocorrect aberrations, to calibrate the global and/or regional optical responseover ‘n’ waves of modulation, to sequence at a user defined frame rate, andto monitor the SLM temperature.
Global or Regional Calibrations - Regional calibrations provide the highest
spatial phase fidelity commercially available by regionally characterizing thephase response to voltage and calibrating on a pixel-by-pixel basis.
