Product Selection Guide

The team at Marktech understands first-hand the vital importance of knowing the required proper wavelengths for a given application, and how vital that data is to the proper matching of LED emitters and detectors.

With that in mind, we are pleased to present this Marktech Spectrum Selector Guide, a general reference product selection guide, to further assist our customers in making those important determinations.

Whether you are simply using an LED as a visible light source (such as on a VMS sign) or detecting the chemical properties of various materials, it is vital to understand which specified wavelengths are best for your application. Marktech, with more that 35 years of experience in the design, manufacture and testing of optoelectronics components and assemblies, can help to make the specification process a bit simpler.

The Marktech product selection guide is organized by spectral range, beginning with the 265 nm ultraviolet (UV) range, up through the 2600 nm shortwave infrared (SWIR) range. There are three main general product categories: Photodetectors, Emitters and High-Brightness LEDs. Marktech organizes its product groups by wavelengths under each category.

By simply clicking on each button on either side of the spectrum, a listing of all corresponding available standard products matching these wavelengths will appear. In addition, next to each part number, we have attached a copy of the latest product specification sheet and a link (if applicable) to the Digi-Key Electronics website, to assist you in obtaining product samples.  For additional applications engineering assistance, please contact our Latham, New York-based R&D center.

Avalanche Photodiodes

Marktech APD's have an internal gain mechanism, fast time response, low dark current and high sensitivity in the near infrared region. These APD's are recommended for applications that require high bandwidth, or where internal gain is needed to overcome high pre-amp noise. In addition, Marktech APD's provide higher sensitivity than a standard photodiode and are ideal for extreme low-level light detection and short pulse detection.
