Point Source LEDs

Marktech Optoelectronics expands its point source LED lineup with state-of-the-art hermetic SMD-packaged visible and infrared emitters. These LEDs are crafted as ideal short-distance laser alternatives, delivering precise light emissions essential for optical encoders, edge sensors, and light barriers.

Point source LEDs by Marktech Optoelectronics are designed to emit a highly focused beam of light, which is critical for the accuracy and dependability of optical devices. Such precise and stable light sources are vital for the efficient functioning of optical encoders and sensors across various industrial, medical, imaging, and technological applications.

Featuring aperture diameters of 25 µm up to 160 µm and wavelengths of 650 nm and 850 nm, these LEDs can be customized for various applications, encompassing industrial automation, medical diagnostics, and digital communication systems. Several point source LEDs are now available in ATLAS hermetic SMD packaging, which enhances the LEDs' reliability and longevity, particularly in challenging environments, by preventing moisture ingress and protecting against environmental factors. The SMD form factor maintains high productivity in assembly operations.

Marktech's point source LED range expansion broadens its extensive array of LED products and reinforces its status as a key innovator in the photonic sector. This development provides users with advanced solutions that set new benchmarks for performance and reliability for optical applications.
