Thorlabs Chrolis 6-Wavelength High-Power LED Source

Thorlabs’ Chrolis 6-Wavelength High-Power LED Source is a 6-colour light engine for fluorescence excitation applications. The configurable design combines the light from six user-chosen high-power LEDs into a single 3 mm liquid light guide. Users can select from 11 different wavelength options with outputs ranging from 365 to 780 nm, covering all known fluorophores. As experimental needs change the light engine is easily reconfigured, as the LED modules and dichroic mirrors are also available for individual purchase.

Each LED’s intensity can be individually controlled via an easy-to-use graphical user interface, which also offers extensive pulse capabilities. Light pulses are generated internally. For each LED, the pulse parameters can be set separately. The pulses are optimised for fast rise/fall times and offer high-quality waveforms. Via a BNC breakout box, it is also possible to trigger the LEDs from external signals. Alternatively, the pulses generated internally can be used to trigger external devices, such as cameras.
