 Fiber Coupled Violet LED Light Source

 Black-LED-405

The compact fiber-coupled high power Violet LED light source module at 405 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 25 mW of CW power at fiber output. The LED driver supports external modulation, 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.

 Spectrum half width:

 15 nm Typ.

 Power Output:

Black-LED-405 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 POF0.51000 µm35 mW
Thorlabs BFH48-600 Silica High OH   0.48   600 µm12 mW


*1: POF - Polymer Optical Fiber
*2: The measurement done by Ophir Nova II power meter equipped with PD300-UV head. The wavelength was set at 405 nm. The values are for non filtered Black-LED-405.
