LCOS Spatial Light Modulators for color-sequential holographic applications

LETO-3 LCOS Phase Only SLM
HOLOEYE offers three fast Spatial Light Modulator models, which are capable of color sequential phase operation. The LETO-3, LUNA and PLUTO-2.1 devices can address 3 x 8 bit within a frame (180 Hz) using fast display versions for the visible range. The three HD resolution (1920 x 1080 pixel) SLMs also feature an RGB light source sync connector on the driver board for use with RGB color-switchable laser sources. The LETO-3 SLM has a resolution of 1920 x 1080 pixels with 6.4 µm pixel pitch. (more…)

live webinar: Spatial Light Modulators – Status and Potential for Holography

Webinar icon
SPIE Webinar: October 7, 2021 (6:00 pm CET // 9:00 a.m. PT) Spatial light modulators (SLM) play a central role in various application areas such as image projection, wavefront control, and light beam steering. There are liquid crystal as well as MEMS-based modulators. Hosted by SPIE Journal of Optical Microsystems editor-in-chief Hans Zappe of the University of Freiburg and moderated by Harald Schenk of Fraunhofer-Institut für Photonische Mikrosysteme, the webinar will present three talks from SLM experts addressing different complementary SLM variants (more…)

Pattern Generator Software Update (5.1)

SLM Pattern Generator Software
An update for the HOLOEYE SLM Pattern Generator software is availalbe now. Besides some minor bug fixes the following changes were made in version 5.1:  
  • Added support for Direct3D 11.
  • The graphics card used for rendering data can now be changed during the device selection, if desired.
  • Added support for wavefront compensation.
  • Extended system information to make it easier to identify problems / provide support
  • Updated contact form used from the about dialogue.

New LETO-3 Spatial Light Modulator Version

LETO-3 Spatial Light Modulator
We just released a major update for LETO Phase Only Spatial Light Modulator series. The LETO-3 SLM has a resolution of 1920 x 1080 pixels with 6.4 µm pixel pitch. The new driver features a faster pulse addressing frequency which provides a higher dynamic range for addressing voltages. With an adjusted drive sequence and configurations the phase stability was further improved and with that, the diffraction efficiencies could also be enhanced. (more…)

New Version of Pattern Generator Software

SLM Pattern Generator Software
The release of version 5 of the Pattern Generator software is really a big step forward, as we integrated core components of the Display SDK into Pattern Generator, along with almost all Display SDK features which are available now. We also reworked a lot of the user interface to make these new functions more accessible and give the user a better overview of the optical functions applied to the data. (more…)

Major update for PLUTO-2 Phase Only Spatial Light Modulators

PLUTO-2.1 Spatial Light Modulator
We recently released a major update for the PLUTO-2 SLM series. The PLUTO-2.1 features a faster pulse addressing frequeny which provides a higher dynamic range for addressing voltages. With an adjusted drive sequence and configurations the phase stability was further improved and with that, the diffraction efficiencies could also be enhanced. The higher bandwith also increases flexibility in terms of configurations. The SLM devices come with (more…)
