Multi-wavelength fiber coupled LEDs

USA/Canada: +1 (248) 436-8085



The fiber-coupled high power UV, Violet,Blue,Green,Yellow,Red and NIR LED multi wavelength light source modules are effective replacements of lasers and lamps in many applications, such as spectroscopy, bio-illumination and point curing.

Curranty available are FC2-LED, FC3-LED, FC5-LED, FC8-LED and FC10-LED models.
Single channel module is also available
(see Silver-LED ).

Each LED has separate current driver with discrete controls. The driver supports CW and pulsed operation mode.

Each channel manual power control is provided by 10 turns potentiometer with counting dial. The external Analog Inputs provide a simple way of LED output power control by computer through DAC (Digital to Analog Converter).

The external TTL inputs enable external triggering of each LED separately.

Both Analog Inputs and TTL inputs are optically isolated with fast opto-couplers.

The fiber coupled LED sources are ideal for use with various fiber optic spectrometers in continuous, strobe or external triggering measurement mode.

Currently the multi-wavelength fiber coupled light source modules can include any combination of wavelengths from the table below.

 Optional Accessories

 Fiber patch cords:

Various fiber optic patch cords are available for use with the 3-LED or 5-LED products. Most popular patch cords are 1000 / 1500 / 2000 micron core diameter Polymer Optical Fibers (POF) terminated by optical SMA connectors on both sides. Prizmatix can provide Stainless Steel tube at one end of the patch cord instead of the SMA connector. This configuration is more convenient in some applications. See more info.

 Fiberoptic Collimator:

Collimators are required to generate a parallel beam of light out of the naturally diverging light emission from an optical fiber.

Prizmatix collimator is designed to collimate High NA fibers (up to 0.53), such as Hard Polymer Clad fibers and Polymer Optical Fibers (POFs).

 Fiber Bundles:

To combine outputs of multiple LEDs a Y-shaped fiber bundle with two or more input branches can be used. Prizmatix can help to configure and build custom fiber bundles for specific applications. See more info..

 Special Bundles:

For spectroscopy application special fiber optic bundles are very important. Special care must be addressed to eliminate possible cross link between the excitation and the collection fibers. See more info..
