VGA-interface light modulator
PLUTO HoloEye Photonics

The PLUTO phase modulator models are based on reflective LCOS microdisplays with 1920 x 1080 pixel resolution and are optimized to provide a phase shift above 2 π up to 1550 nm. The PLUTO devices are packaged in an very small housing to ensure an easy integration into optical setups and applications. The PLUTO phase modulator series includes 4 versions, optimized for the visible, a version optimized for a broad wavelength band centered at 850 nm, a version for the near infrared around 1064 nm and a version optimized for typical telecommunication wavelengths around 1550 nm to ensure optimal results for specific requirements.

Applications range from holography, lithography, optical metrology, interferometry, optical tweezers, wave front corrections to phase shifting applications. The high fill factor of the display also ensures a high light efficiency.

The displays show a reflectivity of approx. 60% and diffraction efficiencies of more than 80%. Thereby a total light efficiency of more than 50% per addressable diffractive device is possible. The driving of the PLUTO devices is as easy as with all HOLOEYE Spatial Light Modulators. A HDTV graphics card is sending HDTV resolution images to the device (via DVI) with a frame rate of 60 Hz. The Pluto Modulators are easily addressed as an external monitor.
