脉冲LED光源

Nothing could be easier. OBB engineers have developed a broad range of simple， inexpensive， nanosecond pulsed light emitting diodes (LED's) to be used as excitation sources with the EasyLife™ systems. These small but robust light sources are available in a broad range of wavelengths， from UV to NIR. They have excellent pulse to pulse， and long term， stability in their intensity as well as their temporal pulse profiles as is evidenced by the high quality of data the system produces. Switching from one LED to another requires no alignment， and takes only a few seconds. You could not possibly work with any simpler， maintenance-free， light source for fluorescence lifetime research.

脉冲LED的优势

The EasyLife™ pulsed LEDs have certain distinct advantages over more conventional light sources， such as nanosecond flash lamps and lasers.

These advantages are:

• Inexpensive

• Durable

• Require no maintenance

• Very stable pulse sources

• Fast

• Wavelengths from UV to NIR (currently 280–670 nm)

• Small size

• Easily interchangeable (snap in—snap out)

Impressive Pulse Stability

Available LEDs

What you need to do is to select a source or sources. The following list shows you the current choices. To exchange sources is real easy， just snap off and then snap on and it is done—no alignment required.

Below 280 nm we are limited by the current state of the technology for LED’s. Do not despair the future should offer even more choices.
