Marktech - Domed Point Source Surface Mount LEDs Address Sophisticated Optoelectronic Applications

The MTPS4088CP, 880nm point source LED features a 3.5 x 0.94 x 2.2mm package with domed lens, and a typical power output of 3.0mW. Developed primarily for optical encoder, optical switch, scanning and precision edge sensing applications, this ±20° Point Source LED utilizes a unique, LED die configuration which provides an unobstructed, radiated beam pattern by masking the die and relocating the topside electrode (see figure 1). By eliminating the dark spot typically associated with the center of conventional LEDs, the point source LED yields superior results when used with application specific optics to obtain desired radiation pattern characteristics. The device also offers an extremely low thermal coefficient.

In addition to its newest Surface Mount package, Marktech also offers Point Source LEDs in TO-18, TO-46 and Mini Pill packages with other configurations available. Marktech's Point Source LEDs come with or without optics to provide the designer with optimum flexibility in sophisticated design efforts. Point Source LEDs supplied with factory optics provide an extremely narrow, near parallel radiation pattern. The optical grade, parabolic glass lens is specifically designed to optimize the effects of the Point Source chip. Devices supplied without optics are supplied with a glass window allowing the designer to utilize proprietary collimating or other application specific optics to take full advantage of the undistorted beam.
