Marktech Unveils Surface-Mount Point-Source LED
Marktech Optoelectronics has introduced the MTPS4088MC surface-mount point-source light-emitting diode (LED). The MTPS4088MC is designed to deliver consistent performance in demanding environments where space constraints are an issue. The 880nm point-source LED features a 3.5 x 0.94 x 2.2mm package with a flat epoxy lens and a typical power output of 2.0mW. Developed primarily for optical-encoder, optical-switch, scanning and precision-edge sensing applications, this +/-10 point-source LED utilises an LED die configuration, which provides an unobstructed, radiated-beam pattern by masking the die and relocating the topside electrode. By eliminating the 'dark spot' typically associated with the centre of conventional LEDs, the point-source LED yields good results when used with application-specific optics to obtain the desired radiation pattern characteristics, according to the company. The device also offers a low thermal coefficient. In addition to its newest surface-mount pac...
