255 nm – 400 nm
Marktech’s extensive line of ultraviolet (UV) LED emitters comes in a wide variety of packages, with a number of customization options to meet your specific needs.
275 nm – 405 nm
A broad line of single- or quad-
High Power surface mount UV LED emitters are available as standard components, or with Starboard mounting for easy evaluation.
440 nm – 700 nm
Marktech offers the broadest selection of high-reliability standard and custom LED emitter packages and dies, for requirements within the visible light spectrum.
630 nm – 980 nm
Available in numerous package types, both standard and custom near-infrared (NIR) LED emitters are among the most widely specified within this product family by Marktech customers in recent years.
630 nm – 980 nm
Point source emitters from Marktech incorporate both a specially designed LED die and an aperture window, in order to create a precise, unobstructed light output pattern for related application needs.
1020 nm – 1720 nm
Used in many material analysis and machine vision applications, standard and custom short wavelength infrared (SWIR) emitters from Marktech offer high-power, high-speed performance.
280 nm – 2600 nm
With a ceramic package, these low-profile multi-wavelength emitters offer a variety of polarized and non-polarized configurations, in support of either AC or DC operation.
Marktech’s standard and custom high power infrared (IR) emitters, also known as photo reflectors, offer outputs that are two to three times greater than those of our standard devices with similar form factors.
