Black-LED-415

The new 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 new 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. 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.
Spectrum half width: 20 nm Typ.
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	Output Power Typical*²
Toray PGR-FB1000 or Mitsubishi Rayon SH4001	POF	0.5	1000 µm	30 mW
Thorlabs FT800UMT	Silica 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.
