Spatial Light Modulator
Santec 's LCOS (Liquid Crystal on Silicon) Spatial Light Modulator (SLM) is an optical device that precisely controls the phase, amplitude, and polarization of light. Its key features include WUXGA (1920 x 1200) high resolution, 10-bit (1024 levels) phase resolution, and phase stability of less than 0.002π, providing excellent wavefront control performance. Its unique liquid crystal material and reflective structure ensure low flicker and high reliability. Its wide range of applications, from research to industrial use, include numerous customizations realized with Santec 's proprietary Spatial Light Modulator. By optimizing laser light, it contributes to the realization of new processing technologies and highly efficient production processes.
What is a Spatial Light Modulator?
Spatial light modulators are optical devices that electrically control the spatial distribution of light amplitude, phase, or polarization. They are widely used in cutting-edge applications such as holography, AR displays, laser beam shaping, optical communications, and quantum computing, and play an important role in modern optical systems.

Professor Yasuhiro TakakiTokyo University of Agriculture and Technology
Tokyo University of Agriculture and Technology, presents an application example. Spatial light modulators are used in computer-synthesized hologram research. At Tokyo University, Santec's SLMs are used in research on stereoscopic displays, holographic contact lens displays, and digital holography.
Associate Professor Zongwei XuTianjin University
"We use the SLM-200 for laser beam adjustment, wavefront correction, and micro-nanometer processing.
Mr. Christopher PanuskiMassachusetts Institute of Technology
We use the SLM-200 to generate dynamic, large-scale optical focus arrays for applications in integrated photonics and quantum information science.
Dr. Moussa N'GomRensselaer Polytechnic Institute
Manipulating the phase of our input beams to let us interrogate novel materials with very specific electromagnetic interactions. The high dynamic range and numerous wavelength options. The Santec SLMs afford us a variety of avenues to explore when optimizing our experimental designs.
Dr. Hamid Hasani BalyaniNorthwestern University
Using the SLM together with further computational processing, we are able to project a set of 2D object fields onto the SLM and make a 3D object out of it. The Santec SLM converts phase patterns into 10-bit grayscale images helping us to acquire high dynamic range images for our display purposes."
