    摘要: The invention relates to a quasi-monolithic polarization beam splitter assembly for splitting a UV beam into two partial beams, comprising two optical prisms (1) that form a polarization beam splitter (2) and a holding part (6) having no optically effective surfaces, which holding part is connected to the polarization beam splitter (2). The invention also relates to a method for producing such a polarization beam splitter assembly, which is characterized in that even after mounting the polarization beam splitter assembly in an optical mount, the partial beams passing therethrough undergo only a very slight wavefront deformation.

    摘要: To provide a mirror structure capable of reflecting incident light with good efficiency and is excellent in reliability. In a mirror structure which is used under an environment that the maximum irradiance of incident light is 5 kW/m 2 or more and has an area of 0.2 m 2 or more, the mirror structure is characterized in that the mirror comprises a mirror, a supporting member and a resin-made adhesive sheet to glue the mirror to the supporting member, and is structured such that a dielectric multilayer is formed at least on an incident light side surface of a plate-shaped substrate and the mirror has an average reflectance ratio 95% or more for incident light having a wavelength in a range of 400 to 1000 nm.

    摘要: Un système permettant de stabiliser une structure rigide (1) vis-à-vis de déformations thermoélastiques comprend un réseau de raidisseurs (2) connectés à une face postérieure (S2) de la structure rigide, et une structure émissive (10) disposée en vis-à-vis de ladite face postérieure (S2). Le système comprend en outre un ensemble d'isolation radiative (3) disposé entre les raidisseurs (2) et la structure émissive (10), sans masquer des portions (P2) de la face postérieure de la structure rigide par rapport à la structure émissive. Des gradients de température présents dans les raidisseurs et orientés perpendiculairement à la surface postérieure de la structure rigide sont alors réduits, et les déformations thermoélastiques de ladite structure rigide sont diminuées en conséquence. La structure rigide peut être un miroir primaire de télescope susceptible de recevoir un flux thermique variable.

    摘要: A prism unit comprises a prism having at least one optical surface in its inside, and a prism base disposing the prism. The prism base includes at least three seating surfaces that are attached to a surface orthogonal to the optical surface of the prism, and a seating surface bonded part that is bonded to the prism by an adhesive. A groove is formed between the seating surface and the seating surface bonded part.

    摘要: A mirror having improved resistance to heat distortion and loss of dimensional stability when exposed to heat radiation. The mirror has a substrate of glass or plastic having front and back surfaces which can be of similar or different shape, and is coated with similar or dissimilar low-emissivity reflective layers on both surfaces. Radiation is reflected by the back surface (away from the mirror) thereby reducing the amount of energy which is absorbed at the back surface of the mirror. This equalizes the temperature through the mirror and reduces thermally-induced warping of the mirror.

    摘要: Pour fixer un organe optique tel qu'un filtre (12) sur un support (10), notamment afin d'effectuer des observations infrarouge sur un satellite artificiel, on utilise un dispositif (18) comportant des brides (20) vissées dans le support (10) et dont les extrémités oppo­sées sont respectivement en appui sur le support et sur le filtre, une cale (26) de répartition d'efforts étant interposée entre chaque bride (20) et le filtre (12). L'effort de serrage est calibré grâce à une ou plusieurs rondelles élastiques (28) placées entre la tête de chaque vis de fixation (22) et la bride correspondante. Des lames séparatrices (24), de préférence en or, sont placées entre le filtre et les pièces adjacentes, au droit des cales (26).
