Diffractive Optical Elements (DOE)

Diffractive Optical Element utilizes a surface with a complex microstructure for its optical function. The surface structures are either etched in fused silica or other glass types, or embossed in various polymer materials

Microdisplay Technology

LCOS (Liquid Crystal on Silicon) is a reflective microdisplay technology based on a silicon backplane. The electronic circuits controlling the liquid crystals are fabricated on a silicon chip, which is coated with a highly reflective surface…

LCOS Spatial Light Modulators for color-sequential holographic applications

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. Read more →

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

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 Read more →

Pattern Generator Software Update (5.1)

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. Read more →
