產品介紹 Products Information

LCOS-SLM are reflective space light phase modulators that freely modulates light phases. Laser or other irradiation light goes through a phase modulation by the liquid crystal and reflected. The wavefront shape can be controlled freely. Wavefront control of the light can be applied to optical beam photolithography, aberration correction, and the like.

LCOS-SLM是反射性空間光相位調製器，可自由調製光相位。雷射或其他照射光通過液晶進行相位調製並反射。波前形狀可以自由控制。可以將光的波前控制應用於光蝕刻，像差校正等。

Technologies

Optical beam shaping technology

Unlike conventional intensity modulation techniques using masks to block out light to form a desired optical pattern, the LCOS-SLM redistributes the light to generate light patterns efficiently by using phase type holograms.

◎ Optical system

※ High efficiency achieved through maskless design.

Aberration correction technology
Imaging performance is degraded largely by aberrations that are wavefront distortions on any kind of optical system. In a micro- scope, the aberrations cause lower resolution and contrast, and in laser processing, they cause lower processing quality and efficiency, for example. An optimum optical system can be achieved by controlling the wavefront to cancel its distortion.

When aberrations remain		When aberrations are corrected by LCOS-SLM
△ Aberrations (wavefront distortions) affect imaging performance. ・Decreased resolution and contrast during microscope observation ・Decreased processing quality and efficiency		※ An optical system is optimized by controlling the wavefront to correct aberrations.

The driver circuit supports a variety of interfaces to meet your system requirements. The product comes with a DVI interface for evaluation. The product can be customized to meet your needs. For details, consult with your nearest Hamamatsu sales office.

LCOS-SLM (for research applications)-X15213 series

Control your light ! Shape your beam ! Improve your image !

The X15213 series devices are a reflective type of pure phase Spatial Light Modulators (SLMs), based on Liquid Crystal on Silicon (LCOS) technology in which liquid crystal (LC) is controlled by a direct and accurate voltage, and can modulate a wavefront of light beam. The LCOS-SLMs are carefully designed to achieve high light utilization efficiency from various points of view, such as reflectivity, aperture ratio and diffraction noise due to the pixel structure.

The X15213 series can be controlled via a PC using the Digital Video Interface (DVI), which is a standard interface for PC displays. The distortions in the LCOS chip, such as wavefront distortion and non-linear response of the LC, are efficiently compensated by the controller.

Easy PC control, precise and linear phase modulation characteristics can be accomplished with the X15213 series. They can also provide high diffraction efficiency and high light utilization efficiency. We also provide water cooled types with a built-in water-cooled heatsink for improved power handling capability.
