Marktech Multichip Emitters and LEDs Pack Greater Performance

New Line of Multichip Emitters and LEDs positioned for illumination purposes, emission and detection

Marktech Optoelectronics has introduced its new line of multichip led emitters. As electronic products continue to evolve technologically and the push for miniaturization continues, space constraints for electronics continue to be a concern for design engineers. Marktech  specializes in chip on board (COB) solutions where multiple LED die can be placed into a small area that offers advantages over standard packaging. These devices can be utilized for illumination purposes and can greatly enhance emission and detection functions when utilized in sensor applications. With the ability to pack more light emission or light detection chips into an area, performance of the circuit can greatly increase.

mt-multichipsMarktech offers a broad array of multichips in various packages including TO-18, TO-5, PLCC, 5mm ceramic and surface mount. These devices are available in both standard part types and custom assemblies that allow the customer to design their own multichip devices including chip on board. Our standard devices hold anywhere from 2 to 7 chips whereas our COB custom products offer unlimited die options. In addition we offer the design engineer a large choice of emission and detection die beginning at 280nm (ultra violet) to 2600 nm (SWIR) and all materials in between. Combine this with Marktech’s ability to sort for tight tolerances (including but not limited to wavelengths, power output, forward voltage etc.)  You now have a custom device at a cost effective price. Marktech’s standard multichip emitters are available through Digi-key

Understanding Ultraviolet LED Applications and Precautions

Ultraviolet light occurs between the visible and x-ray spectrums. The Ultraviolet wavelength range is specified as 10 nm to 400 nm; however, many optoelectronic companies also consider wavelengths as high as 430nm to be in the UV range. Ultraviolet light gets its name due to the “violet” color it produces in the visible portion of the spectrum although much of the output of UV light is not visible to the human eye.

UV LEDs have seen tremendous growth over the past several years.  This is not only the result of technological advances in the manufacturing of solid state UV devices, but the ever increasing demand for environmentally friendly methods of producing UV light which is currently dominated by mercury lamps. 

The current offering of UV LEDs in the optoelectronics market consists of product ranging from approximately 265nm – 420nm with a variety of package styles including through-hole, surface mount and COB (Chip-On-Board).  There are many unique applications for UV LED emitters; however, each is greatly dependent on wavelength and output power.  In general, UV light for LEDs can be broken down into 3 general areas.  These are classified as UV-A, UV-B and UV-C.  (Read More)
