High Power Black-LED


  The new compact fiber-coupled high power UV, Violet, Blue and Green LED light source modules are effective replacements of lasers and lamps in many applications, such as spectroscopy, illumination and curing.

  These compact modules provide tens of milliWatts of CW or pulsed power at fiber output.

  The LED current controller supports external TTL modulation and CW or chopping mode operation with preset frequency and duty cycle.

  The external TTL input enables synchronous operation with various fiber optic spectrometers such as Ocean Optics in strobe mode or external triggering mode.

  Currently the Black-LEDs are available at following wavelengths:
  • 365nm, 385nm, 390nm, 395nm
  • 400nm, 405nm, 410nm, 415nm,
  • 420nm, 425nm, 430nm, 435nm
  • 440nm, 445nm, 455nm, 460nm
  • 470nm, 480nm, 500nm, 515nm
  • 535nm, 540nm, 595nm

Power output:

  Black-LED power output is limited by the reciprocal fiber characteristics. Larger core and higher NA will increase maximum power output, and vice versa.

  The table below shows a few examples of the CW output power at different fibers:

Fiber brand Fiber type*¹ NA Fiber Core Diameter 365nm 405nm 460nm 480nm
Toray PGR-FB1500 or Mitsubishi Rayon SH6001 POF 0.5 1500 µm 55 mW 35 mW 35 mW 36 mW
Toray PGR-FB1000 or Mitsubishi Rayon SH4001 POF 0.5 1000 µm 50 mW 30 mW 32 mW 32 mW

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...
The output from optical fiber is divergent according to fiber NA. In order to reduce the divergence angle a collimator module can be used. Prizmatix collimator was especially designed to fit thick core high NA Polymer Optical Fibers. See more info...
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...
