摘要： A method for binding a first optical element to a substrate is disclosed. The method may include receiving a first optical element and a substrate. The method may include positioning an indium foil between the first optical element and the substrate. The method may include securing the first optical element to the substrate to produce a pre-bonded assembly, wherein the indium foil is disposed between the first optical element and the substrate. The method may include heating the pre-bonded assembly above a melting temperature of the indium foil. The method may include cooling the pre-bonded assembly. The method may include releasing the pre-bonded assembly, wherein releasing the pre-bonded assembly releases a bonded structure.

摘要： Improved latches for overhead corners which reduce the susceptibility of bundled frame components becoming unlatched and separated due to insufficient torque of latch knobs or to repeated shock. The improved latches retain the prior art notched latches along with their strength and simplicity, but are capable of absorbing shock by accommodating a rotational dynamic present in a latch-to-strike connection rather than attempting to prevent it. One of two styles of moveable, pressure-actuated latch keepers is joined to a notched latch of an overhead frame. One style of keeper provides a barrier into the latch's notch, while another style of keeper provides a barrier relative to the strike's features. The latch keepers provide a predetermined amount of resistance to a radial force applied to the latch. This force retains the strike into the latch's notch in a fully-seated orientation, yet allows for the beneficial shock-absorbing rotational movement of the latch to the strike. This use of pressure-actuated keepers eliminates the need for the prior art latch knob and thus also eliminates the subjectivity associated with determining the proper degree of torque required to sufficiently secure the latch to the strike under a range of conditions.

摘要： A position detection device includes a first position detector, a second position detector, and a signal generator. The first position detector includes a first magnetic field generation unit, a second magnetic field generation unit, and a first magnetic sensor. The second position detector includes a third magnetic field generation unit, a fourth magnetic field generation unit, and a second magnetic sensor. The positions of the second and fourth magnetic field generation units vary in response to variations in a detection-target position. The signal generator generates a position detection signal, which is the sum of a first detection signal generated by the first magnetic sensor and a second detection signal generated by the second magnetic sensor. Each of the first and second position detectors includes a bias magnetic field generation unit.

摘要： A method and apparatus for mounting optical components is described. The apparatus is suitable for mounting multiple optical components and comprises a baseplate having opposing first and second surfaces. Recesses or apertures are formed within the baseplate and are located upon the first or second surfaces so as to define thermally activated optic mounting areas. Pillars are then located within the thermally activated optic mounting areas and these provide a means for attaching the optical component to the baseplate. The employment of the recesses or apertures act to significantly reduce the thermal conduction throughout the baseplate. As a result preferential heating can be provided to the one or more thermally activated optic mounting areas while maintaining the baseplate with a desired mechanical strength. The optical mounting apparatus exhibits a high thermal stability thus making the apparatus ideally suited for use within commercial optical system.
