This configuration includes one controller and one fiber coupling adapter which can be used with various wavelength LEDs. The most popular configuration uses 445 and 365nm LEDs.

A long plastic fiber optic cable is included with an SMA connector on the LED side, and no connector on distal end. The fiber jacket on the distal end is stripped and the cladding removed to allow light to emit from the sides of the fiber for radial illumination.

This popular configuration for LED-NMR spectroscopy and was used in papers such as:

• “Discovery of a Photoinduced Dark Catalytic Cycle Using in Situ LED-NMR Spectroscopy”. September 2018
• “Facile Quantum Yield Determination via NMR Actinometry”  March 2018

Warning: Do not expose fiberoptic to vapors of chemical solvents or allow contact with chemicals that may melt the plastic fiber. Use clear coaxial sleeve inside of NMR tube to sheath fiber optic when in use.
