Novel compact LED multiplexing methods can reduce the space required to meet illumination requirements.

Ben Standish, Bookham Inc.

The much-anticipated availability of LEDs for applications in biophotonics finally is manifesting itself in a new selection of more efficient, longer-lived illumination products. LEDs have long held promise as a simple, low-cost alternative to lasers to improve upon the shortcomings of bulb-based illumination — including short lifetimes, excess heat production and the associated energy wasted in generating it as well as, often, an emission spectrum that is too broad. Successful implementation of LEDs into biomedical instruments is not without serious challenges because Lambertian...Read full article
