MeadowLark Optics Spatial Light Modulators
Based on self-designed LCoS chips
For more than 23 years, MeadowLark Optics has been developing high-quality "Spatial Light Modulators." Meadowlark does not use commercially available CMOS arrays, but designs its own liquid crystal components on silicon (LCoS).
Why choose our Spatial Light Modulators:
High Voltage Backplanes = Fastest Response Times
Meadowlark Optics SLMs use custom backplanes, and proprietary drive schemes to achieve response times down to 1 ms (wavelength dependent). Most other liquid crystal spatial light modulators utilize display backplanes built with standard Nematic liquid crystal, limiting response time to >30 ms.
Highest Phase Stability Commercially Available
Our backplanes are custom designed to allow high refresh rates (up to 6 kHz), and direct analogue 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 analogue drive schemes, as opposed to digital dithering, reduces optical flicker as low as 0.1% (0.001 π radians).
Low Inter-pixel Cross Talk
Our backplanes are custom designed to offer high voltage at the pixel (5 – 10 V). 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 offer SLMs with minimal inter-pixel effects.
Broad Wavelength Capabilities
Meadowlark Optics is the only SLM supplier capable of offering SLMs designed for use from UV (>365 nm) up to the MWIR (3 - 5 μm). Analog is Better - All Meadowlark SLMs have been designed for phase modulation. Unlike many display LCoS backplanes which require a pulse width modulation (PWM) scheme, Meadowlark backplanes utilize analogue voltages at each pixel. This results in a very stable phase response over time.
High Bit Depth Controllers
Meadowlark offers 8, 12, and 16-bit controllers to provide the most linear resolvable phase levels commercially available (up to 500). Fast transfer speeds from the computer to the SLM are offered up to 2 kHz.
