 Fiber Coupled Blue LED Light Source


This new compact fiber-coupled high power RED LED light source module at 630nm is an effective replacement of lasers and lamps in many applications, such as spectroscopy, inspection and component texting. This new member of the modular OptiBlocks family provides >18mW of CW power at fiber output (2000 micron core POF fibers).

The LED driver supports CW or external TTL modulation with user controllable frequency and duty cycle.

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.

630nm Spectrum
 The table below shows a few examples of the CW output power at different fibers:
Fiber brandFiber type*¹ NAFiber Core Diameter Output Power Typical*²
Mitsubishi Rayon Super Eska SH8001 POF 0.5 2000 µm 18 mW
Mitsubishi Rayon Super Eska SH6001 POF 0.5 1500 µm 15 mW
Mitsubishi Rayon Super Eska SH4001 POF 0.5 1000 µm 13 mW

*1: Fiber length ~ 1 m; POF – Polymer Optical Fiber
