HOLOEYE

HOLOEYE offers three different versions of the LETO-3 spatial light modulator, which are optimized for use in different wavelength ranges. Optimized for visible, near-IR up to 1100 nm, fast response (180 Hz).

The LETO-3 spatial light modulator is based on a reflective LCOS (liquid crystal on silicon) microdisplay with Full HD resolution. With a pixel pitch of 6.4 µm and a small pixel spacing of 0.2 µm, the LETO-3 SLM provides a high fill factor of 93 %.

The LETO-3 spatial light modulator provides a reflection coefficient of 62% to 75% (depending on wavelength and version). The device provides diffraction efficiency of more than 80% (diffraction grating with 16 levels), which provides a total light output of ~60%.

The panel versions of the device are optimized for use in different wavelength ranges. Currently available models are visible (420 - 650 nm), near infrared (650 - 1100 nm) and a version for operation in the telecommunications wavelength range - on the order of 1550 nm.

The GAEA-2 Spatial Light Modulator (SLM) consists of a driver with a standard digital video interface (HDMI), a 10 megapixel (4K) phase LCOS microdisplay with 3.74 µm pixel pitch.

Meets plug & play standard and allows phase function to be set via a standard graphics board. The graphics card used must support HDMI-2 and have a minimum resolution of 3840 x 2160 pixels.

PLUTO-2.1 is a plug & play compliant phase modulator that can be set the phase function via a standard graphics board. The green channel of the video signal is used to specify a pattern with 8-bit digitization.

The PLUTO-2.1 Spatial Light Modulator (SLM) consists of a driver unit with a standard digital video interface (HDMI) and an LCOS phase microdisplay with Full HD resolution and a pixel pitch of 8 µm, allowing an active area diagonal of 0.7 inches with an aspect ratio of 16:9.

The PLUTO-2.1 driver features a dual-core ARM Cortex-A9 processor with on-board memory. This allows the user to add their own functions that will be directly processed by PLUTO-2.1. The driver runs on the embedded Linux™ SMP operating system and is equipped with libraries that allow full control of the display and remote control.

The ERIS analog spatial light modulator demonstrates exceptional phase stability, low latency and low crosstalk. 3 versions of the ERIS phase SLM are available, operating in the 420 - 650 nm, 420 - 1100 nm, and 1500 - 1600 nm spectrum bands.

The ERIS spatial light modulator is based on a 0.7 inch LCOS microdisplay with a resolution of 1920×1200 pixels and a pixel pitch of 8 µm. The ERIS SLM is a plug & play phase modulation device that can be accessed with phase functions via a standard graphics board.

The phase function is set using the supplied or standard graphics software. HOLOEYE also provides an SDK with APIs in different languages.

Compact SLM platform for integration into small portable solutions. The LUNA spatial light modulator consists of a driver with a standard DisplayPort digital video interface and a phased array LCOS microdisplay with Full HD resolution, 4.5 µm pixel pitch.

The ASIC driver is embedded in the LCOS microdisplay, saving board space and allowing for a very compact driver. The display can receive video data through the 4-way MIPI DSI port. This takes phase space light modulator technology to a new level of capability.

LUNA utilizes a fast and fully digital addressing system that provides high reliability and a compact driver unit. Each gray level represents the corresponding value of the average voltage on the LCD cell.

It is based on a transparent LCD panel (LC) with a resolution of 1024 x 768 pixels. LC 2012 has a compact housing and is easily integrated into the optical system. Addressing to the device is carried out via standard HDMI interface, brightness and contrast adjustment - via USB interface.

Performs phase and amplitude modulation depending on the system configuration. High transparency and contrast LC panel guarantees excellent image quality. Addressing to the LC 2012 modulator is done via standard DVI / HDMI interface of the graphics board.

HOLOEYE modulators are supplied with additional specialized software for Pattern Generator, which performs calculation of digital holograms (CGH) from user defined images, generation of signals for assigning standard optical functions to the modulator: lenses, gratings, axicons, etc.

A training kit developed by HOLOEYE for laboratory courses in optical physics. The main topics covered in the six experimental modules are: polarization effects, amplitude modulation, phase modulation and Fourier optics.

The main component of the OptiXplorer is the Spatial Light Modulator (SLM) from HOLOEYE, which is based on a transmissive twisted nematic LCD with XGA resolution. Also included are a laser module, two rotating polarizers and some optomechanical components.

LCOS (liquid crystal on silicon) is a reflective LCD microdisplay technology that utilizes an active silicon substrate (backplane) on which the display control circuitry is formed. The pixel control circuitry in this technology is located under the reflective electrodes and does not obstruct light reflection. As a result, a very high modulation fill factor is achieved.

LCOS technology is a powerful combination of two well-developed technologies: IC/CMOS and liquid crystal (LC). LCOS has a significant advantage in high-end projection applications due to IC/CMOS and LC technologies.

The image formed by LCOS microdisplays has less discretization compared to the image formed by lumen-type displays. The technology of LCOS-microdisplays can surpass other display technologies by a set of characteristics (resolution, size, ease of application, high quality and low price) when realizing many applications. When implementing backplane LCOS-microdisplays, a standard CMOS process is used.

HOLOEYE offers a wide range of diffractive optical elements for industry and research. Optical elements from HOLOEYE are made of glass or polymer materials.

Standard diffraction gratings made of glass are widely used in industry and research as well as in teaching laboratories.

Standard diffractive optical elements are made of polymethylmethacrylate or polycarbonate. Due to their dimensions (diameter: 8 mm, thickness: 1 - 2 mm) these elements are perfectly suited to work with various standard models of laser modules. For laboratory use, HOLOEYE diffractive optical elements are supplied in a 12.7 mm diameter steel frame, which allows easy mounting of the elements in standard optics holders.
