Thorlabs' DC3100 Series of Modulated LED Sources is designed for frequency domain Fluorescence Lifetime Imaging (FLIM) and other microscopy applications that require advanced modulated high brightness LED sources. This compact LED source is comprised of a high current and high power driver and a LED head with modulating electronics which is designed for high brightness LEDs with high thermal dissipation losses. The LED is included in the head. There are four standard wavelengths available: 365 nm, 405 nm, 470 nm and 630 nm (other wavelengths on request). Collimated Mounting Adapters for the Microscopes Olympus BX and IX, Leica DMI, Nikon Eclipse (Bayonet-Mount) and Zeiss Axioskop are available as optional accessories (see below). The head mount on these LED sources is also compatible with our SM2 (2.035"-40) Lens Tubes.
This LED driver can be remotely operated using the USB 2.0 connector and the included software package with an intuitive GUI and an extensive driver set. The GUI software, µManager, is a versatile, open source, software platform for automated microscopy. A plugin allows the user to control the LED driver right out of the box.
3 Modes of Operation
- Internal Modulation:
Modulated FLIM Mode (Sine Wave), Adjustable LED Brightness, Modulation Frequency in 0.1 MHz Steps and Modulation Depth in Percent
- External Control:
Customizable External Trigger Mode for non FLIM Applications, Adjustable Modulation Frequency up to 100 kHz, Input Voltage 0 to 10 V (1 V corresponds to 100 mA LED Current)
- Constant Current:
For Visual Inspection, Adjustable LED Current: 0 to 1 A in 1 mA Steps
The driver offers three operation modes for great flexibility in usage and applications. The internal modulation mode is the standard mode for typical frequency modulated FLIM applications. Here the LED's modulation frequency can be set from 10 to 100 MHz in 0.1 MHz steps (depending on the connected LED) together with brightness adjustments and setting the percentual modulation depth via the front panel. An additional external trigger mode offers LED control via an external voltage. Here the modulation is adjustable up to 100 kHz by an input voltage of 0 to 10 V (1 V corresponds to 100 mA LED current). This mode is generally used for non FLIM applications.
For easy visual inspection of the microscopy samples the constant current mode allows to control the brightness of the LED by a non modulating LED current from 0 to 1 A.
The COP series adapters are designed to collimate the light emitted by the LED and mate the LED mounting head directly to the illumination ports on Olympus IX/BX (COP1), Leica DMI (COP2), Nikon Eclipse (COP3), or Zeiss Axioskop (COP4) microscopes. These adapters are available with one of two AR coatings: -A for 350 nm - 700 nm, and -B for 650 - 1050 nm.
The rear of the collimator accepts any of the modulated LED sources described above. To switch between LED sources, simply unscrew the LED housing and replace it with an alternative housing.
