Marktech Optoelectronics Point Source Emitter MTPS3085WS

Point Source Emitters 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. 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.
