MeadowLark Optics Spatial Light Modulators

Op basis van zelf ontworpen LCOS chips

Al meer dan 23 jaar ontwikkelt MeadowLark Optics hoogwaardige “Spatial Light Modulators.” Meadowlark maakt geen gebruik van commercieel verkrijgbare CMOS arrays, maar ontwerpt zelf haar vloeibare kristal componenten op silicium (LC0S).

Waarom u zou kiezen voor onze 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 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 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 analog 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.
