High-Resolution Reflective Phase SLM (2048×2048, LBTEK)
This LBTEK reflective-phase spatial light modulator (SLM) uses a liquid-crystal-on-silicon (LCoS) micro-display with 2048×2048 active pixels and 8 μm pixel pitch, delivering pure phase-only modulation up to 2π at the design wavelength. The high fill factor and low wavefront distortion make it suitable for demanding optical wavefront shaping applications.
Operating wavelength variants cover UV, VIS, and NIR bands. Maximum optical input power is up to 1000 W/cm² (model-dependent), enabling use in high-power femtosecond laser systems. HDMI input + external trigger I/O simplify integration with existing laser setups.
Key Features
- 2048×2048 resolution with 8 μm pixel pitch — high spatial frequency control
- Pure phase modulation, up to 2π@design wavelength
- 8-bit (256 levels) gray-scale depth
- Low wavefront distortion (≤λ/12 at 1550 nm typical)
- External trigger input/output for synchronization
- Liquid cooling option for high-power applications
- HDMI video input — plug-and-play integration
Typical Applications
- Femtosecond laser pulse shaping and compression
- Holographic optical trapping and tweezers
- Adaptive optics — aberration correction
- Beam shaping (top-hat, vortex, Bessel, structured light)
- Multi-spot laser processing / patterning
- Quantum optics experiments — phase-encoded states
- Microscopy — structured illumination, computational imaging
Product Family
The SLM-P series LBTEK reflective phase SLMs offer multi-wavelength options (VIS, IR, VISIR2, HP-IR) covering 400-1700 nm. The HP-IR variant is rated for high optical power up to 1000 W/cm² damage threshold. Custom phase masks, calibration tables, and AR coatings available on request.
