A laser optical system using optical fiber transmission, includes a first optical fiber for transmitting laser light emitted from a laser oscillator, a collimator lens for collimating laser light emitted from the first optical fiber, a spherical array lens including a plurality of cells for converging laser light emitted from the collimator lens into a plurality of spots, a plurality of second optical fibers each having a smaller core diameter than the first optical fiber and configured to admit the laser light converged into the corresponding spot by the spherical array lens, the second optical fibers having output ends that have mutually parallel axial lines and are arranged linearly in a single row, and a linearization optical unit for shaping laser light emitted from the second optical fibers into laser light having a linear cross section at an illuminated surface.

According to the present invention there is provided a system of panels which could for instance be used for a suspended ceiling comprising one or more rows (R1, R2, . . . ) of panels (2), where one or more of the panels (2) of a given row can be moved from a first, upper level (a), where the panels are fixed relative to the system to a second, lower level (b), where the panels can be displaced along and underneath panels situated at the first level, thereby providing access through the system of panels to the space above or behind the panels. According to the invention there is furthermore provided panels for such systems, the panels comprising a substantially rigid frame (6, 12), the frame being furthermore provided with means for cooperation with mating means on a suspension and guide system, thereby allowing said movement from one level to the other and vice versa and said displacement. The frame defines an open, central region, over which a suitable, flexible material can be stretched and there is disclosed alternative attachment means for this material to the frame. The system of panels according to the invention facilitates access to the region above or behind the panels and also transport of the panels to the site of application as well as replacement or change of appearance of the panels on site.

A bioreactor container comprising has an at least locally flexible wall and at least one container opening. The wall of the bioreactor container has a fluid-tight inner sheet, and an at least locally fluid-permeable or structured outer sheet. A method for testing the integrity of the bioreactor container also is provided.
