High Voltage Backplanes = Fastest Response Times Meadowlark Optics SLMs use custom backplanes, and proprietary drive schemes to achieve response times Resolution: 512 x 512 Array Size: 7.68 x 7.68 mm Pixel Pitch: 15 x 15 µm Wavelength Wavefront Distortion down to 2 ms (wavelength dependent). Most other liquid crystal spatial light modulators Highest Phase Stability Commercially Available - Our backplanes are custom designed to allow high refresh rates (up to 6 kHz), and direct analog drive schemes. Refreshing the voltage at the pixel at rates far surpassing the response time of the liquid crystal ensures high temporal phase stability. Further, use of direct analog drive schemes, as opposed to digital dithering, reduces optical flicker to the noise floor of detectors. Low Inter-pixel Cross Talk - Our backplanes are custom designed to offer high voltage at the pixel (5 – 12 V), and a large pixel pitch. Further, our SLMs are built with Meadowlark Optics proprietary liquid crystal which minimizes the required thickness of the LC layer in the SLM. By maximizing the ratio of pixel pitch to LC thickness we are able to Liquid Crystal Response Time (Standard Efficiency / High Efficiency) Model P512/PDM512 utilize display backplanes built with standard Nematic liquid crystal, limiting response time to >30 ms.
