Point Source Emitters

Cathode

Product Overview

Emitting Light

P-Layer

Active Area

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.

STANDARD LED

The Point Source series outperforms standard emitters at high

speeds yielding a stable output pattern and making them the

device of choice for applications which include encoders and

linear positioning equipment. High reliability package options

range from TO-18 and TO-46 metal cans to ceramic surface

mount packages. Varying package heights and lensing options

provide the designer with optimum ﬂexibility in sophisticated

design efforts. Devices supplied without optics are manufactured

with a ﬂat glass window allowing the designer to utilize proprietary

collimating or other application speciﬁc optics to take full

advantage of the undistorted beam. Custom packaging designs

which include Chip on Board conﬁgurations or custom apertures

are also available.

Unobstructed Light Output Narrow Spectral Bandwidth

In a simple side by side lighting comparison, the light emitted form

the Standard LED (left) has several dark spots due to the wire

bonding pad and obstruction from the wire bond. The Point Source

Emitter (right) has a narrow, well deﬁned and precise light output

pattern.

A key feature of the the Point Source LED series is a very narrow

spectral bandwidth. Custom sorting of wavelength as well as other

key parameters is available. Please contact Marktech to discuss the

application.
