Multi-Wavelength Fiber-Coupled LED Sources (up to 8 wavelengths) Description：

Datasheet

Mightex WFC-series multi-wavelength fiber-coupled light sources are enabled by the latest LED technologies, and Mightex’s proprietary beam combining and coupling optics. Up to eight (8) LEDs are coherently combined into a single multi-mode fiber with the highest efficiency practically possible. Each LED can be powered individually or simultaneously to produce a tunable spectrum.

The light sources are offered in two configurations: the standard configuration and the high-power configuration. Neutral beam combiners are used in the standard configuration. The standard configuration has the advantage of low cost and the most flexible wavelength plans. Any wavelength and white color may be combined in the standard configuration. For applications that require the highest possible output power, however, one should choose the high-power configuration where high-efficiency dichroic beam splitters are used to combine different wavelengths. Because not all possible dichroic beamsplitters are in stock, some wavelength combinations may require customization. Please contact us with your detailed wavelength plan to obtain a quotation for custom higher-power configurations.

A wide range of LED wavelengths from 365nm to 940nm and white colors are available for users to choose from. The selected LEDs are installed in the light source chassis in the factory. Fiber coupling is through a standard SMA port, and hence customers may use different fibers with the LED source according to the specific requirements of their applications. SMA-connectorized fiber patchcords are available in various core diameters and numerical apertures.

A 4-channel light source includes a 5-ft electrical cable, and an 8-channel source includes two such cables. Each cable has an 8-pin locking connector on one end to be plugged into the light source, and four pairs of bare-wire terminals at the other end. Each pair of terminals should be connected to a separate channel of a LED controller. Users can drive the installed LEDs individually or simultaneously using a Mightex multi-channel LED controller or other constant current sources. A cooling fan with heat sinks is built into the light source. When two or more wavelengths are running at full power, the fan should be turned on to maintain low temperature of the LED junctions, in order to prevent LED damage due to over-heating. A separate power supply is included for driving the cooling fan.

Mightex 4-channel multi-wavelength light source can be ordered with 2 and 4 wavelengths, and the 8-channel source can be ordered with 6 and 8 wavelengths. In the standard configuration (which is NOT supported by the 8-channel source due to low efficiency), output power of each wavelength decreases with the total number of wavelengths, while in the high-power configuration the output power does not change much with number of wavelengths.
