Black-LED-365

The new compact fiber-coupled 365 nm LED light source module is an effective replacement of UV lasers and Hg lamps in many applications, such as spectroscopy and fluorometry. This new member of the modular OptiBlocks family provides >40mW 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.

Features

• High Power
• Narrow UV spectrum emission FWHM~10 nm
• Excellent for fluorescence excitation
• LED spectrum can be narrowed by optional band pass filter
• Compact and robust head: 50mm x 50mm x 40mm
• Precisely adjustable power
• TTL external modulation
• Long life (no lamp replacement required)

Specifications

Peak wavelength: 365nm typ.
Spectrum half width: 8nm
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
Mitsubishi Rayon SH6001 Super Eska	POF	0.5	1500 µm	50 mW
Mitsubishi Rayon SH4001 Super Eska	POF	0.5	1000 µm	45 mW
Thorlabs BFH48-600	Silica High OH	0.48	600 µm	15 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 365nm

Optical output connector:
The Black-LED is available with SMA, FC or ST reciprocal fiber connector.
