Meadowlark High-Speed Reflective Phase SLM
This Meadowlark Optics Full HD (1920×1200) liquid-crystal-on-silicon (LCoS) spatial light modulator provides reflective phase modulation with 60 Hz monochrome (or 180 Hz color) refresh. The 9.6 mm × 15.36 mm active area with 8 μm pixel pitch supports complex wavefront generation for advanced photonics labs.
Multiple wavelength-optimized variants (400-800 nm, 500-1200 nm, 850-1650 nm) cover visible through SWIR bands. HDMI video input + external trigger I/O simplify lab integration.
Key Features
- 1920×1200 resolution (Full HD format)
- 60 Hz monochrome / 180 Hz color refresh rate
- 8 μm pixel pitch, 15.36×9.60 mm active area
- Phase modulation up to 7.1π at 450 nm (model-dependent)
- Multi-wavelength variants (VIS, NIR, SWIR)
- External trigger input/output
- Compact 121×73×22 mm form factor
Typical Applications
- High-speed beam steering and scanning
- Adaptive optics in biomedical imaging
- Holographic display research
- Coherent control experiments
- Industrial laser pulse-shaping
- Computer-generated hologram (CGH) projection
