Digital Silicon/Analog Silicon Liquid Crystal Spatial Light Modulators
SBN Series Liquid Crystal Spatial Light Modulators(SLM)
Our spatial light modulator (SLM) is based on reflective liquid crystal on silicon (LCOS) micro-display technology. The SLMs enable optical phase modulation freely and generate arbitrary 2D phase patterns on a LCOS pixel-by-pixel basis. SBN-RD series are our latest Full-HD LCOS model. The SLMs are suitable for various scientific and industrial applications, including beam shaping, wavefront correction and optical manipulations.
Applications:
HUD
Micro-projection
Holographic imaging
Optical communication
Optical forceps
Light field regulation
Adaptive optics
Beam shaping
Laser processing
Product model naming rules:
Serial Number - Modulation Type - modulation Mode - Resolution - Pixel Size - Window - Optional wavelength - Others
For example: SBNA-PP2K-6355-NIR-H, SBNA series, Phase modulation, analog control, resolution 1920*1080, pixel 6.3m, window 0.55, wavelength NIR-H 1064nm (high power version)
This series of spatial light modulators (SLMS) are a high-resolution version of digital silicon based liquid crystals (LCoS). It provides up to 4160×2460 resolution and allows dynamic adjustment of modulation region, so it is suitable for multi - mode or single - mode high - resolution optical system applications.
Features/Advantages:
Easily calibrated
Digital drive, flexible modulation
Easy to use, plug and play
Good linearity of amplitude/phase gray curve
High resolution, high phase accuracy and good phase stability
