IR Detectors

Pyroelectric IR detectors are thermal detectors and have a very wide spectral bandwidth.  Even so, they are mainly used in the MWIR and LWIR - and increasingly also for THz radiation.

PbS Detectors

PbS Detectors detect infrared radiation in the wavelength range between 1 µm and 3.3 µm.

PbS detectors offer high sensitivity at a low price. They are the perfect solution for large-area IR detectors.

PbSe Detectors

Polycrystalline lead selenide (PbSe) is a standard semiconductor detector with a sensitivity of between 1 µm and 5.2 µm.

Our IR Detectors

Panchromatic, photoconductive and thermal detectors

InGaAs PIN Photodiodes

Modern InGaAs PIN photodiodes are panchromatic and convert broadband light to photocurrents in the Visible-NIR range. Concretely speaking, this means a sensitivity range from 500 nm to 1700 nm for regular InGaAs and – in increments – up to 2600 nm for extended InGaAs.

 

PbS and PbSe Detectors

PbS is a standard Short-Wave Infrared (SWIR) semiconductor detector (1 - 3.3 µm) whereas PbSe is used in the Mid-Wave Infrared (MWIR) range (1 - 4.7 µm when uncooled; up to 5.2 µm when cooled). Our PbS and PbSe detectors are photoconductive; the detector resistance is reduced during illumination. The crystal structure is polycrystalline and is produced via chemical deposition. 

Pyroelectric IR Detectors

A pyroelectric IR detector is a thermal detector in that it responds to the change in heat (IR) absorbed on its surface. Thermal detectors are polychromatic with a very wide spectral bandwidth.

The nature of the pyroelectric effect is that in a highly-ordered crystal (or ceramic), a temperature change in the element causes its atoms to move slightly out of position. This rearranges its electrical charge, which is measured in the electrodes on its surface.

The pyroelectric effect is found in many materials.  The most commonly-used materials are deuterated lanthanum α alanine-doped triglycine sulfate (DLaTGS) and lithium tantalate (LTO).
