ClearSource LED emitters enable precision sensing and detection
Standard LED optical sensors use a top-mounting wire bond to connect the LED chip to the anode or cathode. The bond wire obstructs the light output, giving rise to dark spots and patches in the beam which makes precise sensing and detection more difficult. In OMC’s new ClearSource series, the wire is bonded to the side of the chip, leaving the output beam unobstructed. This produces a defined light beam which enables high-accuracy sensing and detection. For even greater precision measurements that require near-parallel light emission, lenses can be incorporated. Additionally, this die-bond configuration reduces capacitive effects within the diode, enhancing switching speed and reliability.
According to OMC, ClearSource emitters also benefit from LED technology’s inherent high reliability and long lifetime. The devices have a low sensitivity to ESD, and are suitable for a wide range of applications including encoders, linear positioning, line and edge sensing, medical equipment, fibre optic systems, machine vision, optical switching, distance and range finding.
Devices are available with standard apertures for 650nm and 850nm LEDs with ball-type narrow beam, flat, dome, or drip encapsulation lensing options.
