1 General Information
The Chrolis 6-Wavelength High-Power LED Source is a light source featuring up to six different
LED modules ranging from UV to IR. The light output of the LEDs is combined via dichroic mir-
rors and coupled into a Liquid Light Guide (LLG). The LLG can for example be coupled to a mi-
croscope for fluorescence imaging or any other application where multiple wavelengths of light
are of use. In addition to generating CW light, the Chrolis has extensive pulse capabilities.
The Chrolis is a modular device and allows the user to configure a light source with LED mod-
ules of different wavelengths and corresponding dichroic mirrors most suitable for the individual
application. The Chrolis is available as two pre-configured devices with preselected LEDs of dif-
ferent wavelength, the CHROLIS-C1 and CHROLIS-C2, or as a configurable item CHROLIS.
Available LED modules for the configurable CHROLIS are listed on the Thorlabs website of the
Chrolis . Further, the user can insert a bandpass filter after each LED to restrict the excitation
wavelength. The LEDs and dichroic mirrors are mounted on an actively cooled heat sink and
the temperature of the LED modules is continuously monitored to ensure highly stable perfor-
mance.
This multichannel light source is compatible with Thorlabs' Ø3 mm liquid light guides. The tip of
the liquid light guide is cooled using thermoelectric coolers (TECs) to extend the lifetime of the
LLG.
The Chrolis is controlled by the Chrolis software via a USB interface. The software recognizes
the assembled LED configuration which is then displayed with the respective spectra. The
Chrolis software allows the user to set the intensity for each LED as well as to modulate the
LEDs for pulsed light applications without the use of an external function generator.
A BNC breakout box (available separately) allows input and output of TTL signals to link the
LED modulation with the timing of external devices. The BNC Breakout Box can be configured
with the Chrolis software for the following applications: (1) direct modulation of the LEDs by an
external TTL signal, (2) triggering internal modulation by an external TTL signal, (3) generating
a TTL output signal for other devices.
