HOLOEYE introduces 13 new of off-the-shelf standard glass diffractive optical elements. These stock elements are made of Fused Silica glass by etching and feature an anti-reflective (AR) coating on both sides of the glass substrate. The DOEs are optimized for a wavelenth around 800 nm. (more…)
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…)
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…)
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…)
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…)
We released a new compact phase only Spatial Light Modulator series. The LUNA SLM is based on an 0.39" LCOS microdisplay with a resolution of 1920 x 1080 pixels and 4.5µm pixel pitch. The SLM provides linear 8 bit phase levels and is addressed via DisplayPort at 60 Hz input frame rate. The driver also features an USB connector for power and advanced configurations (more…)
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…)
We recently added 4 new standard polymer Diffractive Optical Elements with different patterns for wavelengths around 450 nm. HOLOEYE offers a broad range of standard polymer DOEs. Standard Diffractive Optics are a fast and low cost way for proof-of-concept and product developments. With a standard size of 8 mm in diameter (more…)
