Thorlabs Introduces Configurable 6-Color Light Source for Microscopy

Newton, NJ – May 11, 2020 – Thorlabs has announced the release of its new 6-Color Light Engine for fluorescence excitation applications. The configurable Chrolis™ design combines the light from 6 customer-chosen high-power LEDs into a single Ø3 mm liquid light guide. Users can select from 11 different wavelength options with outputs ranging from 365 nm to 780 nm, covering all known fluorophores.

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 optimized for fast rise/fall times and offer best-in-class 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.

"We are excited to introduce this new high-end LED source, which is designed, developed, and produced by Thorlabs’ Munich-based team," noted Bruno Gross, General Manager of Thorlabs GmbH. "Over the next year, we are planning to expand this product line with additional optical, electronic, and software features."
