    Abstract: A laser power meter incorporating an absorber disc with a peripheral thermopile ring, either continuous or segmented, and an additional temperature detection element in the central portion, that enables measurement of beam size. This detection element can be a thermopile element, generally a ring of smaller diameter than the peripheral thermopile used, and located closer to the center of the absorber disc. With this arrangement the beam size can be measured, in addition to measurements of the power and the position of the beam. Alternatively, this centralized detection element can be a single thermocouple junction located at the center of the disc, which acts as the hot junction of a thermocouple pair. The second or cold junction is effectively located on the disc close to the peripheral thermopile. Alternatively, two temperature measuring elements can be used, one at the disc center and one at the periphery.

    Abstract: An infra red camera assembly, with elements efficient in raw material use, simple to produce and which provides a high level of performance. The assembly uses a three element design, with a main lens, and with both the entrance window and the detector array protection window having some optical power, such that the refractive power of the lens assembly comprises up to four surfaces spread over three elements. The lens assembly comprises (i) a front element which has one surface flat, and which can thus also serve as the input window, (ii) a rear element which has one surface flat, and which can thus also serve as the detector window, and (iii) a single central lens element which, because of the combined use of the two other optically active window elements, does not require any steeply formed surfaces, such that it is also material efficient and economical to produce.

    Abstract: A photodiode detector for measuring beam power, impingement position and size. The detector has pairs of electrodes positioned at peripheral edges of a resistive surface of the detector, and an additional electrode positioned in the center of the resistive layer. The peripheral electrodes measure total power and beam position, and the central electrode additionally enables measurement of beam size. The voltage detected on the central electrode, when normalized for the power of the incident beam, provides a measure of the beam size, since the larger the beam, the less the Ohmic voltage developed on the electrode relative to the peripheral electrodes. The normalization to the power of the incident beam can be performed against the total sum of the currents collected from the peripheral electrodes, this summed current being proportional to the incident power. The voltage developed on the central electrode is proportional to the reciprocal of the beam diameter.

    Abstract: A power measuring sensor for an optical beam which utilizes the temperature difference across a thin layer of heat insulating material, generated by the axial flow of the absorbed beam, from an absorber layer on which the beam impinges, to a cooled heat sink which dissipates the heat after passage through the sensor. The axial heat flow is measured by means of a continuous matrix of adjacent thermocouple junctions over the heat flow region of the sensor disc, with the thermal insulating layer, which generates the temperature drop, having thicker and thinner regions at alternate junctions. The junctions on the thicker regions of the insulator thus become the hot junctions, and those on the thinner regions of the insulating layer become the cold junctions, and the sum of the voltages generated by the thermocouples is proportional to the flow of heat, and thus to the incident optical power.

    Abstract: An optical power meter using a thermal detector, with improved response time, in which a fast response sensor is mounted close to the thermal detector, in such a location that it senses a part of the incident beam to be measured. The output signal of the fast response sensor, and the output signal of the thermal detector are electronically combined, such that response characteristics of the fast response sensor are impressed on the output of the thermal detector, thus providing a power meter combining the power handling ability and the accuracy of the thermal detector with a response characteristic of the fast response sensor. This method of combining fast and slow response sensors is also applicable to other measurements, whether physical, chemical or biological, such as those of flow, velocity, temperature, pressure, electrical, electronic, magnetic, thermal, optical, radiative, dimensional or acoustic properties of a material or article.

    Abstract: A method for centering a circular optical element using a non self-centering chuck adapted to grip the element at two strengths. The element is rotated in the chuck while measuring the lateral position of its outer rim with a probe. The positions of maximum and minimum run-out of the element as a function of its angular position are determined. Chuck rotation is stopped at an angular position with the maximum rim run-out positioned at a predetermined point. The chuck grip is reduced such that the element is still held in the chuck but can be moved in a lateral direction without damaging its surface. The element is moved in a direction connecting the predetermined point of maximum run-out and the axis of rotation of the chuck, in order to reduce the run-out of the element. The procedure is repeated until the desired centering is achieved.
