The invention relates to a method for producing window elements which can be soldered into a housing in a hermetically sealed manner and which have an optical coating, and to free-form window elements produced in accordance with the method. The problem of the invention, of finding an improved possibility for producing optical window elements which can be soldered into a housing in a hermetically sealed manner and which have an optical coating, said window elements permitting a permanently reliable gas- and vacuum-tight solder connection to a metal housing, is solved according to the invention in that, after the typical application of optical coatings (2), a protective layer (3) in the form of a sacrificial layer that can be etched is applied to the optical coating (2), both layer systems (2, 3) are selectively removed by means of a processing beam (4) of high-energy radiation in order to remove a desired optically active free-form surface (61) in the edge areas (62) thereof by local processing for window elements having an arbitrary geometric design, so that the protective layer remains on the optical coating as a lift-off mask, which is lifted off by an etching process that selectively attacks only the protective layer and not the optical coating after the application of a metallisation (7) for a solder layer (8), and the metallisation is retained only on the peripheral edge areas (62) that surround the free-form surfaces.

There is provided an infrared sensor and a holder which is capable of preventing optical filters from being contaminated by adhesives used to fix filters to the detection element (infrared sensor element). A holder 20 included in an infrared sensor includes accommodation parts 21a and 21b that accommodate optical filters, recess parts 23a and 23b that are provided on the opposite surface 20a of the holder 20 which faces the to the infrared sensor element and are placed apart from the accommodation parts 21a and 21b, a groove 25a that is provided on the opposite surface 20a and is placed between the accommodation part 21a and the recess part 23a, and a groove 25b that is provided on the opposite 20a and is placed between the accommodation part 21b and the recess part 23b. The depth d2 of each of the grooves 25a and 25b is greater than the depth d1 of each of the recess parts 23a and 23b. In a process of adhering the infrared sensor element to the holder 20, an adhesive is applied to the recess parts 23a and 23b.

The invention relates to an infrared thermometer with a heatable measuring tip, especially a fever thermometer for measuring temperature in the ear, and a heatable protective cap. Said measuring tip has a radiation input area at its front end, where a heating element is also situated. The heating element is either connected to a protective cap that can be slid onto the measuring tip or fixed on the front end of the measuring tip.

An object of the present invention is to provide an infrared detector that is strong against mechanical impacts and enables mounting for various applications to be carried out readily and reliably. An infrared detector 1 includes: a base member 10, positioned at a lower portion; an infrared detecting chip 20, mounted on the base member 10 and for detecting infrared rays; an optical window chip 30, positioned above the infrared detecting chip 20 and for transmitting infrared rays; and bonding wires 38, connecting terminals of the infrared detecting chip 20 with terminals of the base member 10, and a portion below a predetermined distance from an upper surface 30a of the optical window chip 30 is coated by a coating member 40. By interposition of a spacer 36, the optical window chip 30 and the infrared detecting chip 20 form a sealed space 34 that houses an infrared photosensitive portion 23.
摘要:
Bei einem Verfahren zur Herstellung von in ein Gehäuse hermetisch dicht einlötbaren Fensterelementen und einem gehäuseabdichtenden Fensterelement besteht die Aufgabe, eine verbesserte hermetische Abdichtung zwischen Fenster und Gehäuse durch eine erhöhte Haftung und Homogenität bei der Metallbeschichtung zu erreichen und ein Eindringen von Streulicht oder Störstrahlung zu vermeiden. Optisch durchlässiges flaches Trägermaterial, dessen Größe ausreichend ist für eine Vielzahl von Fensterelementen, wird auf mindestens einer Oberfläche mit einer optischen Beschichtung versehen, von der anschließend auf einer beschichteten Oberfläche rahmenförmige Teilbereiche, welche optisch wirksame Flächen der Fensterelemente umschließen, entfernt werden, wonach auf die erzeugten beschichtungsfreien Teilbereiche eine zur Herstellung einer Lötverbindung mit dem Gehäuse dienende Metallbeschichtung aufgebracht wird und eine Vereinzelung der Fensterelemente aus dem Trägermaterial erfolgt. Eine optische Versiegelung zwischen einem zur Metallbeschichtung gehörenden Lötschichtsystem und der optischen Beschichtung verhindert ein Eindringen von Störstrahlung.

摘要:
A nondirectional infrared detector element using a pyroelectric member, sensitive to the movement of an object in any directions, is provided for an infrared sensor unit and an infrared detector. The infrared detector element comprises a pyroelectric member (11), on one side of which are provided first infrared-absorbing electrodes (12 and 13) that are substantially trapezoidal and are connected electrically to have opposite polarities, while on the other side are provided a pair of electrically-connected second electrodes (14 and 15). The first trapezoidal electrodes (12 and 13) and the second trapezoidal electrodes (14 and 15) are arranged so that their base sides can be in the same direction. This infrared detector element is sensitive to the movement of an object in any direction.

A compact wide field of view, infrared imaging system (100) for detecting two Mid-Wave Infrared “MWIR” and, optionally, an additional one Long-Wave Infrared “LWIR” band, has a single, color corrected lens element (133) and a detector (124) within a dewar assembly (106). The lens element (122) has two aspherical surface profiles and utilizes a holographic optical element to manipulate bands of energy that are harmonic components of each other. An exemplary infrared imaging apparatus performs at an F-stop “F/#” of at least 1.4 with a square field of view of 90x90 degrees.
