High-Field NMR illuminator

As for the illumination experiments at high-field NMR, the illumination device, in-situ NMR illuminator, provides a compact and user-friendly adaptation to attach the light source kit directly to the sample tube with a light guide deep into the sample.

For whom do not have High-Field Field-Cycler, the high-speed sample shuttling system, we also provide an option, the fixed-field NMR illuminator, to perform the photo-related NMR experiments at commercial high-field NMR spectrometers. The major components of this NMR illuminator are a light source module and a light guide to couple the light directly to samples inside the NMR tube. The compactness of our in-situ NMR illuminator implements photo-related experiments without additional hardware requirements in an NMR spectrometer.

Key features:

  1. Seamless Integration: The entire set integrates the light guide with the light source, eliminating the need for additional hardware.
  2. Universal Compatibility: The light guide is designed to fit the inner diameter of conventional 5mm liquid-state NMR tubes, ensuring compatibility with standard equipment.
  3. Optimized Output: Featuring a 4mm-diameter output for efficient light coupling inside the NMR tube, ensuring precise and reliable results.
  4. Versatile Lighting: Equipped with high-power LEDs, users can choose from optional wavelengths directly installed on the light guide, offering flexibility for various experiments.
  5. Easy Installation: Designed for effortless installation onto commercially available NMR tubes, saving time and effort in setup.
  6. Precise Synchronization: The system synchronizes illumination timing with NMR pulse programs through TTL triggers, ensuring accurate data acquisition.
  7. User-Friendly Control: Utilizing computer aid, users can effortlessly control light powers and select from various illumination timing modes, enhancing experimental control and customization.
  8. Compact and Portable: Engineered to be compact and easy to handle, facilitating seamless integration into experimental setups while ensuring convenience and portability.
  9. Ready-to-Use: With this set, users can directly initiate experiments without the need for self-made additions or additional add-ons, streamlining the experimental process and minimizing setup time.
