Marktech Optoelectronics Photodiodes

Marktech Optoelectronics Photodiodes provide the optimum balance between low dark current, high speed, and light sensitivity. The features of the Photodiodes allow for increased flexibility and options in a variety of applications, ranging from fiber optics and high-speed optical communications to medical and chemical analysis.

The Marktech Optoelectronics Photodiodes offer a large assortment of photodetectors from standard Silicon detectors, including photodiodes, phototransistors, avalanche photodiodes, and InP/InGaAs PIN photodiodes.

The standard photovoltaic Silicon photodiodes offer spectral sensitivity in the 400nm to 1100nm range for spectroscopy equipment and any light sensing application requiring broadband sensitivity with enhancements in the blue/green region. The silicon phototransistors offer spectral sensitivity in the 400nm to 1100nm range for applications requiring very high sensitivity, uniform response, and increased reliability, such as card readers and optical sensors. The Silicon Avalanche Photodiodes (Si APD’s) are designed for high speed and low light level detection in the NIR spectrum, optimized for 800nm or 905nm peak response. Additionally, InGaAs PIN Photodiodes have a spectral sensitivity in the 600nm – 1750nm range, a high-sensitivity, and high-reliability product series, ideally suited for optical communications devices.
