LED Source LEDD3

Thorlabs has released its modulating LED Source LEDD3, which is designed for frequency domain fluorescent lifetime imaging (FLIM) and other microscopy applications that require modulated high brightness LED sources (HBLEDs).

The LEDD3 source comprises a non-switching high current driver plus a HBLED head with passive cooling for high thermal dissipation losses.

The driver is compact, easy to use and offers three operation modes for flexibility in usage and application. The first mode is for frequency modulated FLIM applications offering modulation frequencies from 10 to 100MHz. A second mode offers modulation control via external trigger for frequencies up to 100kHz. In the third mode an adjustable constant current can be set for visual inspection of samples.

The LEDD3 head offers flexible mounting options. Via a 2-inch external thread different collimation optics can be connected.
