 UV, Violet, Blue, Green, Yellow, Red NIR LED Fiber-Coupled LED Light  Sources



Silver-LED is a series of fiber-coupled LEDs. Silver-LEDs are high power UV, Violet, Blue, Green, Yellow, Red or NIR LED light source modules. These fiber-coupled LEDs are effective replacements of fiber-coupled lasers in many applications, such as spectroscopy, illumination and curing. These compact modules provide high power CW low noise output as well as fast pulsed operation.

The TTL input enables external triggering. The Analog input (0-5Vdc) enables control of output power from computer equipped with digital to analog module (D/A).

Silver-LED is ideal for use with various fiber optic spectrometers in continuous, strobe or external triggering measurement mode. The Silver-LEDs are available at standard wavelengths as in the table below.
Other wavelengths are available on request.

 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..
