 Fiber Coupled Violet LED Light Source

 Black-LED-415

The compact fiber-coupled high power Violet LED light source module at 415 nm is an effective replacement of lasers and lamps in many applications, such as spectroscopy and fluorometry.

This member of the modular OptiBlocks family provides up to 30 mW of CW power at fiber output. The LED driver supports external modulation, CW or chopping mode operation with preset frequency and duty cycle.

 Specifications:

 Peak wavelength:

 415 nm Typ.

 Spectrum half width:

 20 nm Typ.

The peak wavelength is current and temperature dependent. The peak wavelength can be blue shifted by up to 4 nm at 100% max output power.

 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 NAFiber Core Diameter Output Power Typical*²
Toray PGR-FB1000 or Mitsubishi Rayon SH4001 POF 0.51000 µm 30mW
Thorlabs FT800UMTSilica High OH 0.39 800 µm 17 mW
Thorlabs BFH48-600 Silica High OH   0.48    600 µm 12 mW
 *1: POF - Polymer Optical Fiber. Fiber length ~1m.
 *2: The measurement done by Ophir Nova II power meter equipped with PD300-UV head.
 The wavelength was set at 415 nm. The values are for non filtered Black-LED-415.

 Optical output connector

 The Black-LED is available with SMA, FC or ST reciprocal fiber connector
