HT-2 : Holotomographic microscopy with 3D fluorescence imaging capability
Research and diagnosis in the life sciences depends on the information that can be found using cellular analysis. However, current microscopy techniques limit the quantity and quality of information available to researchers and clinicians
The HT-2, a microscope that displays both 3D holograms and 3D fluorescence imaging, is able to overcome these limitations through use of new and existing technology. Its abilities can enable researchers and clinicians to break into new frontiers of understanding, diagnosing, and treating disease.
HT-2 is the world’s first microscopy combining both holotomography and 3D fluorescence imaging in one unit.
The HT-2 is an update to our HT-1 microscope. The HT-1 microscope uses holotomographic technology to measure the 3D and 4D refractive indexes using a dynamic micromirror device (DMD) to add unprecedented stability and precision to the performance of the microscope. These innovations allow for quantitative, label free imaging of cells. The HT-2 has all the capabilities of the HT-1, but combines the holotomographic imaging capabilities of the original version with the added ability to perform fluorescence microscopy.

LUNA Phase Only Spatial Light Modulator (Reflective)
The LUNA phase only Spatial Light Modulator (SLM) consists of a driver unit with standard digital video interface (DisplayPort) and a phase only LCOS (Liquid Crystal on Silicon) microdisplay with full HD resolution (1920 x 1080 pixel) and 4.5 µm pixel pitch leading to an active area diagonal of 0.39” with an aspect ratio of 16:9.
The LUNA Spatial Light Modulator is our most compact SLM platform for integration into small sized or even portable solutions.
The LUNA phase only Spatial Light Modulator (SLM) consists of a driver unit with standard digital video interface (DisplayPort) and a phase only LCOS (Liquid Crystal on Silicon) microdisplay with full HD resolution (1920 x 1080 pixel) and 4.5 µm pixel pitch leading to an active area diagonal of 0.39” with an aspect ratio of 16:9.
The driver ASIC is embedded in the LCOS microdisplay itself. This saves board space which enables a very compact driver and makes integration more convenient. The standard driver box has a size of only 84.4 x 47 x 28.8 mm. The display can even accept video data input via a 4-lane MIPI DSI. This brings phase only Spatial Light Modulator technology to a new level of potential for industrial implementations.
The LUNA SLM usees fast full digital addressing which assures high reliability and a compact driver unit. A certain gray level represents a defined average voltage across the LC cell. This voltage leads to a variable tilt of the LC molecules due to their electrical anisotropy. As LC molecules also show optical anisotropy this tilt changes the refractive index of the LC molecules (for incident polarization along the long display axis) which causes a modified optical path length within the LC cell. The addressed gray level is converted into a phase level.
The LUNA driver unit is equipped with an USB interface for changing the voltage vs. phase level distribution (gamma control) and dynamic range (voltage across the LC cell) in order to calibrate the SLM for different wavelengths.
The LUNA SLM is a plug & play phase modulator and can be addressed with phase functions via standard graphics cards as extended monitor device. Addressing can be done using the supplied Pattern Generator software, the HOLOEYE Slideshow Player software or standard image viewer software. HOLOEYE also provides an SLM Display Software Development Kit (SDK) which provides APIs (Application Programming Interface) for different programming languages.
