PLUTO HDTV phase only SLMs   

PLUTO Series   

  • Reflective LCOS (Phase Only) display
  • Dielectric mirror coated versions available
  • 1920 x 1080 HDTV resolution, 8 µm pixel pitch
  • Frame rate: 60/180 Hz
  • Up to 93% fill factor
  • 2π up to 1550 nm
  • 15.36 x 8.64 mm (0.7" diagonal) active area
  • 8-bit (256 grey levels) addressing
  • HDMI & USB interface (PLUTO-2)

The PLUTO phase only Spatial Light Modulators (SLMs) are based on reflective LCOS microdisplays delivering 1920 x 1080 pixel resolution with an 8 µm pixel pitch. The SLM panel's high fill factor ensures a high light efficiency, the active area being 0.7” diagonal with an aspect ratio of 16:9.

PLUTO is plug & play, offers fast full digital addressing, and can be programmed with phase functions via a standard graphics card as an extended monitor device using the supplied software.

HOLOEYE offers different panel versions optimised for use with different wavelength ranges, and their new dielectric mirror versions enable use with higher incident power lasers due to the coating's reduction of absorption.

PLUTO-2 driver

The new enhanced PLUTO-2 driver features an HDMI interface for addressing phase functions, a USB connection for advanced calibrations, and a trigger sync output for synchronising with external devices - such as colour-switchable lasers. The PLUTO-2 driver's faster addressing speed allows for a colour-field-sequential (CFS) mode at 180 Hz input frame rate and, as a bonus, also offers a more stable phase response.

The PLUTO-2 driver is equipped with a dual-core processor and on-chip memory, enabling user-programmed (Ubuntu™) additional functionality. For example, a slideshow of images can played back from a USB stick or internal memory.

High retardance

Panels are available with considerably higher phase retardation in comparison to the standard models, enabling up to 4π or even up to 6π phase functions to be addressed. This can be beneficial for wavefront functions, as it enables higher slopes and reduced transition points compared to the usual 2π encoding.

For some applications a stable phase response is required, and this can be accomplished by driving the High Retardance panel with 2π phase retardation settings. The driving forces to the LC molecules in such a configuration are reduced, so response time is slower, but the phase signal typically shows a standard deviation of 0.2-0.7% (wavelength dependent).
