Prizmatix High Power Fiber Coupled Three LED Light Source

  • FC3-LED Triple Wavelength Fiber Coupled LED Light Source


The Prizmatix FC3-LED light source is a compact fiber-coupled LED system consisting of 3 independent high power LEDs at specified wavelengths, with an SMA fiber connector for each one. 

This light source is available in a wide range of wavelengths (365nm- 940nm). Its advanced low noise LED driver electronics support CW and fast TTL pulsing. A ten turn potentiometer enables precise power adjustment and the analog input (0-5 Vdc) enables control of output power from a computer via a digital to analog (D/A) converter. There is an option for built-in USB interface for use with LabView, Matlab, and other software that can send HyperTerminal commands.

With power output of up to >220mW for each fiber, the FC3-LED is an excellent choice for a high power fiber coupled LED source.

Note: The power output of the FC-LEDs varies with the fiber characteristics. Larger core diameter and higher NA will increase power output.  See Power Output Table.

Optical fibers are not included and are made to order. Design your fibers here
Custom fiber bundles for combining outputs into one output available on request.

When multiple wavelengths in a single fiber are needed, the Prizmatix Mic-LED with our Beam Combiner module and Fiber Coupler are recommended. (See Relevant Add-Ons)
For higher power requirements Prizmatix Ultra High Power or Optogenetics LEDs are recommended.

Call or chat with our sales consultant for help choosing the ideal fiber or to discuss your application.

  1. Prizmatix FC3-LED light source 4 Star Review

    Posted by on 3rd Mar 2014

    So far, an easy to use assembly of LED UV light source and POF optic fiber for bech-scale photocatalytic experiments; reasonable flexibility for irradiance/fluence dependent reaction kinetic studies made possible by adjustible photopower in combination with other features such as collimation et cetera.
