Since the proper wavelengths are critical in matching both LED emitters and detector we are pleased to present the Marktech Spectrum Selector Guide©.

Whether you are simply using an LED as a visible light source (such as a VMS sign) or to detect the chemical properties of various materials, understanding what wavelengths work best is crucial. Marktech with almost 30 years' experience in the optoelectronic industry helps make things a bit simpler by presenting our spectrum selector guide.

The guide is organized by the spectrum range beginning at the 265nm UV (ultra violet) range and going up to 2600nm (shortwave infrared). There are three product categories beginning left to right, Detectors, Emitters and High Brightness LEDs. Marktech groups its various products by wavelengths under each category. By simply clicking each button on either side of the spectrum a listing of all our products that correspond to these wavelengths will appear. In addition next to each part number we have attached the spec sheet and a link (if applicable) to Digi-key to obtain samples.

CREE Surface Mount

Offered in industry-standard packages, Cree surface mount (SMD) LEDs have high-reliability and high-brightness performance. They are designed to work under a wide range of environmental conditions, making them ideal for use in illumination applications. The wide viewing angle makes them suited for channel lettering, as well as general backlighting and illuminating applications. Their flat-top emitting surface makes it easy for SMD LEDs to mate with light pipes.

CREE P4

The Cree P-4 package design allows lighting designers to reduce the number of necessary LEDs while simultaneously providing a more uniform and unique illuminated appearance compared to other LED solutions. This is possible through the efficient P-4 optical-package design, high current capabilities, and improved thermal dissipation. Cree P-4 LEDs are made with an advanced optical-grade epoxy that offers superior performance in high-temperature and high-moisture environments. The encapsulation resin contains anti-UV material in order to reduce the effects of long-term exposure to direct sunlight.
