摘要:
An optical projection unit comprising a first optical element module and at least one second optical element module is provided. The first optical element module comprises a first housing unit and at least a first optical element, the first optical element being received within the first housing unit and having an optically used first region defining a first optical axis. The at least one second optical element module is located adjacent to the first optical element module and comprises at least one second optical element, the second optical element defining a second optical axis of the optical projection unit. The first housing unit has a central first housing axis and an outer wall extending in a circumferential direction about the first housing axis. The first optical axis is at least one of laterally offset and inclined with respect to the first housing axis. Furthermore, the first housing axis is substantially collinear with the second optical axis.

A shielding device (20) for optical and/or electronic apparatuses (16) is described, wherein said apparatuses may cooperate with incident electromagnetic radiation (X1, X2), in particular for space telescopes, the shielding device including: - at least a filter (24, 26) provided for interacting with said incident electromagnetic radiation (X1, X2), for selectively filtering said radiation; and - a support structure (22) for the filter. The support structure (22) is an inflatable structure, which is able to achieve an operating stand-by configuration, in which it is substantially folded together, and an active operating configuration, in which it extends along the longitudinal extension axis s (ZZ), and is essentially completely unfolded. Furthermore, the filter (24, 26) includes a filter body, which is provided in order to be transversely positioned with respect to said longitudinal extension axis, when the support structure reaches its active operating configuration.

摘要:
A portable folding virtual reality glasses with adjustable focus having a headband, a first supporting piece, a second supporting piece, an accordion folding piece and an eyeshade component, inner and outer sides of the headband are adhered and connected. A terminal supporting plate is provided between the front of the headband and the first supporting piece. A first supporting piece eyehole is provided at the front of the first supporting piece. When the virtual reality glasses is unfolded, the back ends of the first supporting piece extend to the eyeshade component and adhere to the eyeshade component. The inner side of the first supporting piece is provided with the second supporting piece. The accordion type folding piece is provided between the second supporting piece and the eyeshade component. The virtual reality glasses can be completely folded through the accordion type folding piece, compressing the size in the folded state to the minimum for easy carrying. The virtual reality glasses also has a reliable structure and is comfortable to wear. It can effectively avoid a light break-in and is advantageous for promotion.

摘要:
A culture observation apparatus (100), which is used for observing a cultured cell (502) while culturing the cell (502), includes a culture device that cultures the cultured cell (502), and a microscope used for observing the cultured cell (502). The culture device includes a first space (202) that is controlled to an environment suitable for culture of the cell (502), and a second space (156) that is controlled to a lower humidity condition in comparison with the first space (202). The microscope includes an objective optical unit (310) including an objective lens (312; 810; 820; 830; 840; 850); the objective optical unit (310) having at least one portion located in the second space (156), and another portion extending into the first space (202) through an opening (146b) formed in a partition wall (146) that separates the first space (202) and the second space (156), with a gap between the objective optical unit (310) and the partition wall (146) being sealed by a sealing member (222), and the objective lens (312; 810; 820; 830; 840; 850) includes a plurality of lens groups (814A, 815A, 816A; 814B, 815B, 816B; 814C, 815C, 816C), with mutual spaces (A, B; A, B, C; D) among the lens groups vented to the second space (202).
