THORLABS EXULUS-4K1 Instructions Manual page 2

highly stable with minimal fluctuations and minimal crosstalk with adjacent
pixels. For maximum phase shift values, refer to the table to the upper right.
These spatial light modulators provide far more pixels than lower-order phase modulators such as segmented or deformable mirrors. For applications requiring
improved thermal stability and high-power handling (≤200 W/cm) in the 400 nm to 850 nm or 650 nm to 1100 nm wavelength ranges, high-power SLMs are
available.
Exulus spatial light modulators are driven by an input video signal and operate as a general Full HD, WUXGA, or 4K screen. They are bundled with a software
GUI that provides complete control over the device. Different driving modes are supported by the software, including full frame, image input, video input, Fresnel
lens, diffraction, and computer-generated holography (CGH). The CGH mode also allows tilting and focusing effects to be overlaid onto a pattern. The GUI
enables quick switching between operating modes, as well as allowing images, videos, and patterns to be uploaded to the panel. For more details on the
operating modes, please see the Software and App Note tabs.
Standard Models
Each standard spatial light modulator (EXULUS-HD1, -HD2, -HD3, -HD4, and -4K1) includes a built-in SLM panel with independent horizontal and vertical tilt
adjustment of ±3.2°. Locking rings are installed to fix the adjustment settings, as well as provide extra stability. Customized versions are also available with the
panel separated from the control unit; contact Tech Support for details.
These Exulus spatial light modulators have input ports compatible with HDMI* connectors and ship with two corresponding cables: one for connecting to an
HDMI-compatible output, and one for connecting to a DisplayPort*-compatible output. Also included are a mini-USB cable for connecting to a PC, a power supply
with a location-specific power cord and a HKTS-5/64 hex key thumbscrew for adjusting the horizontal and vertical tilt adjusters.
High-Power Models
Each high-power SLM (EXULUS-HD2HP and EXULUS-HD3HP) features a liquid-cooled SLM head and adapter board, which can be mounted directly on the
controller or positioned separately from the main housing. The SLM head includes two preinstalled 1/4" hoses with CPC
for easy connection to a chiller, and the adapter board houses the FPC connectors and a circuit board that connects the controller and SLM head. We
recommend using Thorlabs' LK220 chiller (sold below) for full compatibility with the Thorlabs EXULUS software package.
These high-power spatial light modulators have input ports compatible with HDMI* connectors and ship with two corresponding cables: one for connecting to an
HDMI-compatible output, and one for connecting to a DisplayPort*-compatible output. A mini-USB cable is also included for connecting to a PC. To aid in
connecting to a liquid chiller, two CPC valved quick-connection fittings for both 4.3 mm (0.17") and 6.0 mm (0.24") inner diameter hoses are included with the
unit, as well a 2.5 mm stereo cable for thermistor compatibility. A power supply with a location-specific power cord, a USB drive with the software and manual,
and a BD-2M 2 mm balldriver for removing the adapter board and SLM head from the main unit are also shipped with these Exulus models.
