Absorbed photons produce charge carriers that are collected at the contacts, resulting in external photocurrent. Photovoltaic detectors have complex current/voltage characteristics. The devices can operate either at flicker-free zero bias or with reverse voltage. Reverse bias voltage is frequently applied to increase responsivity, differential resistance, reduce the shot noise, improve high frequency performance and increase the dynamic range. Vigo System’s PV, PVI, PVM and PVMI series are based on sophisticated HgCdTe heterostructures for the best performance and stability. The devices are optimized for the maximum performance at λopt. The PV series features 2.5 µm to 6.5 μm HgCdTe uncooled, ambient temperature IR photovoltaic detectors. Cut on wavelength can be optimized upon request. Reverse bias may significantly increase response speed and dynamic range. It also results in improved performance at high frequencies, but 1/f noise that appears in biased devices may reduce performance at low frequencies. PV series devices are also available with 2 µm to 12 μm HgCdTe detectors that are thermoelectrically cooled by two-stage (PV-2TE series), three-stage (PV-3TE series) or even four-stage (PV-4TE series) TEC structures.

Responsivity 3.5 kV/W Typ.; Max. Noise 50 µVpp; Spec. Detectivity 17 x 107cm*√Hz/W; FoV (Horizontal/Vertical) 77°/77°, 135°/120°; Operating Voltage 2-10 VDC Single-element pyroelectric detectors (PIR) are often applied for temperature and gas measuring applications in one-channel or dual-channel variants, which is then one output per element. Excelitas offers its PYS Series of single-element pyrodetectors as thermally compensated devices. The principle of gas monitor application is called NDIR. NDIR requires detectors with narrow-band optical filters. Excelitas provides a range of suited filter windows for those gases which show an absorption band in the IR spectral range. Excelitas’ PYS 3198 TC GX (replacement to LHi 807) is a single-channel, parallel format temperature-compensated elements PIR detector based on lithium-tantalate (Li-Ta). In the design for PYS 3198 TC, a single sensing element is placed in the center of the detector. For thermal compensation an additional element, (which is blinded from radiation), is connected in parallel. The TO-5 metal housing is equipped with an optical filter window. For gas measurement applications with Excelitas’ single-element pyrodetectors, typically the spectral range is narrowed to match the gas absorption in the IR range. As such the window is acting as a narrow-band optical filter. Almost like two detectors in one housing, the PYS 3428 (replacement to LHi 814) dual-channel, single-element pyrodetector includes two single-elements which are each thermally compensated by an additional blinded element sitting aside. Each output is optically linked to an individual optical window within the TO-5 metal housing. For each window, a variety of narrow-band optical filters are available to meet a range of specific sensing requirements. Each element has its own individual output signals, thus the name dual-channel. Since the PYS 3428 Pyrodetector has been specifically designed for gas measuring applications, it comes with narrow-band optical filter windows. Typically, one window is used as reference, for which Excelitas provides the filter version G20 as the reference window. The PYS 3928 TC digital dual-channel pyrodetector includes two single elements, both thermally compensated by an additional blinded element sitting aside. Each element is digitized and available as a 2x16-bit output at the digital link pin. Each element is optically linked to an individual optical window within the TO-5 metal housing. For each window, a selection of narrow-band optical filters is available to meet your specific detection requirements. As part of Excelitas’ DigiPyro series, this design offers the output of both sensing elements as a 2x16-bitstream of the direct link. With this 16-bit resolution, smaller noise values are given per digit. Since the PYS 3928 TC DigiPyro PIR has been designed especially for gas measuring applications, it comes with narrow-band optical filter windows. Typically, one window is used as reference, for which Excelitas provides the filter version G20. For the second window, various suited narrow-band filter windows are available.
