InGaAs Photodiodes

Our InGaAs photodiodes are sensitive to light in the visible to infrared regions (400-1700nm). These photodiodes are designed to offer high sensitivity with low dark currents, which makes them optimal for low-light detection applications commonly used in fiber optic communications, spectroscopy, industrial/process control, and military systems. We offer a diverse range of InGaAs photodiodes that include options for extended wavelength detection, position sensing, and custom capabilities based on your exact specifications. 

InGaAs Quadrant Segmented Photodiodes (QPD)

These quadrant photodiodes have four discrete active areas, enabling precise locating and alignment of 900-1700nm light. They feature high responsivity, low crosstalk between elements, and fast response, making them ideal for beam profiling, nulling, and centering applications.

InGaAs Positive Sensitive Detectors (PSD) (400-1700nm)

Lateral-effect position-sensitive InGaAs photodiodes can detect light position across a wide spectrum from visible to NIR (400-1700nm) and provide spatial resolution along with output current proportional to position. They enable precision locating, tracking, and alignment applications.

InGaAs Extended Visible (400-1700nm) Photodiodes

Sensitive devices detect across a broad spectral range from visible to near-infrared wavelengths (400-1700nm) for analytical instrumentation and optical communications.

InGaAs Standard Range (900-1700nm) Photodiodes

These photodiodes are highly sensitive and detect near-infrared light with a spectral range of 900-1700nm. They are ideal for applications such as fiber optic communications, spectroscopy, and laser power monitoring.
