Handheld LED Brilliance Found Nowhere Else

The Technology Challenge

Since the beginning of endoscopy, providing sufficient illumination has been difficult.

With the advent of LED light source technology, many of the problems of weight, size, heat and noise have been eliminated, but the challenge of getting enough light remained. With as much as 60% of the light generated by a typical LED never making it to the fiber optic, most of the light was being wasted. Acera has solved the problem of how to fully harness the light output of an LED into the fiberoptic.

So What is the Problem?

It's all about the angles

An LED emits light in a hemispherical pattern with a 180 degree output angle. However an optical light guide will only accept light which arrives within a 27 degree cone. Any light outside that cone just goes through the side of the fiber and is lost.

Problem Solved

The Acera TIR (Total Internal Reflection) lens collects about 90% of the light coming from the LED and directs it into a beam of the correct angle to enter the light guide.Thus this innovative technology delivers much more light to the scope.

The most advanced LED technology on the planet

That’s it! You have to see the result to believe it. More light at the distal end of the light guide than you would believe possible.
