Point Source Emitters
Available from Marktech Optoelectronics
The Marktech Point Source Emitter series incorporates a specially designed LED die and aperture window to create a precise, unobstructed light output pattern. The key design feature of the Point Source LED die is a wire bond which attaches next to the emission window as opposed to the center of the window eliminating any dark spots in the light output pattern. Traditional wire bonding of a standard LED emitter die is attached to the top center of the die which creates a "dark spot" and therefore will effect the light output from device to device. These variations in light output of a standard LED emitter can have a negative affect in a critical sensing application.
