Multi-Wavelength Fiber-Coupled LED Sources

Overview
Specifications

Multi wavelength fiber coupled LED light source (up to 8 wavelengths)

The Gewu Optical Multi wavelength Fiber Coupled Light Source adopts the latest LED technology and Goptica's proprietary beam combination and coupling optical devices. Up to eight (8) LEDs are coherently combined into a multimode fiber with the highest efficiency. Each LED can be powered individually or simultaneously, making the WFC series a new type of light source with adjustable spectra.

The light source offers two configurations: standard configuration and high-power configuration. The standard configuration uses a neutral beam combiner. The standard configuration has the advantages of low cost and the most flexible wavelength planning. In the standard configuration, any wavelength and white color can be combined. However, for applications that require the highest possible output power, a high-power configuration should be chosen, where an efficient dichroic beam splitter is used to combine different wavelengths. Due to the fact that not all possible dichroic beam splitters are in stock, certain wavelength combinations may require customization. Please contact us and provide your detailed wavelength plan to obtain a quote for customized high-power configurations.

There are multiple LED wavelengths to choose from, ranging from 365nm to 940nm, with white color. The selected LED is installed in the light source chassis in the factory. Fiber optic coupling is performed through standard SMA ports, so customers can use different fibers with LED light sources according to their specific application requirements. SMA connector fiber jumpers have various core diameters and numerical apertures.

The 4-channel light source includes a 5-foot cable, and the 8-channel light source includes two such cables. Each cable has an 8-pin locking connector at one end that can be plugged into a 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 the LED controller. Users can use Mightex multi-channel LED controllers or other constant current sources to drive installed LEDs individually or simultaneously. The light source is equipped with a cooling fan with a built-in heat sink. When two or more wavelengths are operating at full power, the fan should be turned on to maintain the low temperature of the LED junction to prevent damage to the LED due to overheating. Contains a separate power source to drive the cooling fan.

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

Important note: (1) LEDs can only be driven by a constant current source and cannot be driven by a voltage source (such as a battery or AC/DC power supply); (2) Before applying current to the LED, be sure to verify the rated current of the LED and always ensure that no current exceeding the rated current of the LED is applied.
