Point Source Emitters

Wavelengths:
625nm to 850nm

Marktech’s Point Source Emitters are powered by a unique LED chip that produces a well-defined pattern of light similar to a “point”. These chips in combination with high quality grade glass lenses produce an extremely narrow, near parallel radiation pattern. This unobstructed, radiated beam pattern is made possible by producing a unique defined active area and relocating the topside electrode. By eliminating the “dark spot” typically associated with the center of conventional LEDs, the point source LED yields superior results in critical sensing applications. Our Point Source Emitters are available in TO—18, TO-46 and PLCC-4 packages.

Marktech can customize both chip and component packaging depending on the application. Die aperture windows are available up to 200um. Lensing options are available depending on the beam output desired. The Point Source is a suitable alternative to laser diodes in short range applications offering increased temperature range capabilities and reduced risk of discharge due to ESD.

Available in a wide variety of packages with various viewing angles, Point Source LED die feature 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. The Point Source series outperforms standard emitters at high speeds, yielding a stable output pattern.

Typical industries served:
Medical, manufacturing, communications, industrial

Common applications:
Encoders, linear positioning, line sensing, medical sensing, short-haul fiber, machine vision, edge sensing, optical switches
