Marktech offers a large assortment of photo detectors ranging from standard silicon photo diodes to InP Pin Photo Diodes. Our standard InP photo diodes have a spectral sensitivity range in the 400nm to 1000nm range for applications such as optical switching and sensing requiring high speed, consistency and high reliability. Marktech manufactured InP Pin Photo Diodes using InGaAs/InP technology with a spectral sensitivity in the 800nm to 1750nm range for applications requiring low dark current, high speed and sensitivity such as fiber optics and optical communications. In addition Marktech offers Photo Transistors using silicon detectors in the 400nm to 1100 range for applications that require very high sensitivity, uniform response and increased reliability such as card readers and optical sensors. Marktech's detector die can be placed in a variety of packages from metal can TO-5, TO-18 and TO-46 to surface mount and standard 3mm and 5mm plastic packages. We can also incorporate the detector die in custom designed assemblies.
