New LCOS Spatial Light Modulator

Hamamatsu Photonics, one the world’s leading manufacturers of innovative opto-electronic products, introduce the new Liquid Crystal on Silicon spatial light modulator (LCOS-SLM), the X10468.

This compact system features high light utilization efficiencies (95%), high diffraction efficiencies close to theoretical maximum values and high precision phase modulation control with excellent linearity providing industry leading performance. Furthermore, compared to the previous generation of spatial light modulators, this new SLM offers a high-speed response and a higher power handling capability due to its package type, large active area and optimised dielectric mirror coatings.

There are many applications for the LCOS-SLM including laser material and micro-processing due to its high power handling capability and ophthalmology where high quality imaging can be obtained with wavefront corrections. Other applications include optical manipulation (holographic optical tweezers), pulse shaping, laser beam steering, optical testing, astronomy and many more.

Hamamatsu is collaborating with academic institutions including the Optics Group at the University of Glasgow where the X10468 has been used in Quantum Optics experiments. Professor Miles Padgett, the Head of Research, comments that “the X10468 combination of high diffraction efficiency, low aberrations and ease of interfacing makes them ideal for our Ghost Imaging Experiments”.
