摘要:
A sensor (30) for detecting electromagnetic radiation comprises a sensor element (10), a housing (31, 33) in which the sensor element is disposed, and a radiation inlet window (35) provided in the housing and closed by a material (32) transmissible for the radiation to be detected. The transmissible material (32) is fixed to the housing by fixation means (38) not disposed in the field of view of the sensor element.
摘要:
A radiation sensor (10) comprises a support (1), a cavity (2) which may be a recess or a through hole formed in one surface of the support (1), a sensor element (4, 4a, 4b) formed above the cavity (2), preferably on a membrane (3) covering the cavity (2), and electric terminals (5, 5a, 5b) for the sensor element (4, 4a, 4b). The cavity (2) in the surface of the support (1) has a fully or partly rounded contour (2a).

摘要:
A radiation sensor (10) comprises plural radiation sensing elements (1) arranged along an arrangement line, a lens having an optical axis focusing radiation towards the sensing elements, and circuitry (2) receiving the electric signal of the sensing elements and providing an output signal. The midpoint of the arrangement line may be offset against the optical axis of the converging section (5). At least some of the sensing elements may have different sizes. At least some of the sensing elements may have different relative sensitivity compared to each other. Two or more pairs of adjacent sensing elements may have a different pitch.

A sensor cap assembly includes a radiation shielding part provided with a radiation entrance opening, and a radiation-transmissive lens mounted from the outside to the shielding part. The lens is a thick lens with a ratio T/D of thickness (T) to diameter (D) of more than 0.10, preferably more than 0.15.
摘要:
A heater (15) for a sensor (10) comprises a substrate (20), an electrically conductive heating structure (21) on the substrate (20), and one or more connecting portions (28) for electrically connecting the heating structure (21) to one or more outside terminals (14) of the sensor (10). The substrate (20) is rigid and can comprise ceramics, preferably alumina ceramics.

A pyroelectric material is made of lithium tantalate treated to an extent that a bulk resistivity is in a range of less than 2e+14Ω*cm, preferably less than 5e+12Ω*cm, but more than a lower threshold is obtained.
摘要:
A radiation sensor (10) comprises one or more radiation sensing elements (1) providing an electric signal in dependence of incident radiation, a housing (4, 5) confining the sensing element and permitting incidence of radiation from outside onto the sensing element, plural terminals (7) for supplying electrical power to the sensor and at least for outputting a sensor output signal, and circuitry (2) receiving the electric signal of the sensing element and providing the output signal in accordance with the electric signal of the sensing element. The circuitry comprises a switching signal circuitry for generating an on/off output signal for a switchable component external to the sensor and/or a digital output signal circuitry for providing a multiple bit serial output signal, and the sensor has one output terminal (7a) for outputting the on/off output signal or the multiple bit serial output signal.
摘要:
A thermopile sensor array is provided. The thermopile sensor array may include multiple pixels formed by multiple thermopiles arranged on a single common shared support membrane. A separation between the edge of the shared support membrane and the outermost thermopile(s) may be included to provide additional thermal isolation between the thermopile and an underlying silicon substrate.
