Stable, high-precision LED source for microscopy

Thorlabs' (Dachau, Germany) LEDD3 series modulating LED source is designed for frequency domain fluorescent lifetime imaging (FLIM) and other microscopy applications that require modulated high brightness LED sources (HBLEDs). The first in a new line of ultra stable HB-LED drivers and light sources for demanding scientific applications from Thorlabs, LEDD3 comprises a non switching high current driver plus a HBLED head with passive cooling for high thermal dissipation losses.

The driver is compact, promises ease of 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 100 MHz. A second mode offers modulation control via external trigger for frequencies up to 100 kHz. 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" external thread different collimation optics can be connected. Collimation optics that are compatible with the following microscopes are optionally available: Olympus BX & IX, Leica DMI, Nikon Eclipse (F-Mount), and Zeiss Axioskop.
