Abstract: The invention relates to a diffusing device (10, 12, 14), to a safety-glass panel (100, 110), to a light source (200) and to a greenhouse (300). The diffusing device according to the invention comprises a first surface (20) and a second surface (22) arranged opposite the first surface. Each one of the first surface and the second surface constitutes a border between two transmissive media which have different refractive indexes (n1, n2). Each one of the first surface and the second surface further comprise a substantially continuous wave pattern (30, 32) constituted of protrusions (40) from the first surface and from the second surface and of indentations (42) in the first surface and in the second surface for diffusing impinging light via refraction. The wave pattern (30, 32) comprises a relatively smooth pattern (30, 32).

Abstract: An coated translucent substrate that comprises a translucent substrate, an anti-reflection coating and a conductive oxide coating and a process for manufacturing the same is provided. The translucent substrate has a first surface at a first side. The anti-reflection coating is provided at the first side of the translucent substrate to reduce the reflection of light by the coated translucent substrate. The anti-reflection coating is applied to the conductive oxide coating. The conductive oxide coating is arranged between the first surface of the translucent substrate and the anti-reflection coating to reduce the transmission of light in the near infrared spectrum through the coated translucent substrate. The conductive oxide coating comprises SnO2:F. The coated translucent substrate transmits relatively good light in the Photosynthetically Active Radiation spectral range and blocks the light in the Near Infrared spectral range.

Abstract: The invention provides a light reflector comprising a light reflecting surface, which reflector comprises a layer of a porous inorganic material having a thickness in the range of from 0.1 to 100 mm, which inorganic material has a pore volume in the range of 2 to 80% and an average pore size in the range of from 100 nm to 50 ?m. The invention further provides an apparatus comprising the reflector, and a method for preparing the reflector.

Abstract: The invention provides an optical light reflection method for measuring the actual thickness of a transparent oxide layer having a general thickness of less than 33 nm which layer is applied onto a glass container, in which method use is made of a light source for emitting UV-light to the glass container, means to collect directly reflected light and scattered reflected light from the glass container, and means to determine the thickness of the layer on the basis of the information provided by the reflected light. The invention further relates to an apparatus for carrying out the present invention.

Abstract: A beam is reflected and/or transmitted by a sample with a coating. The path of the beam has a unitary path part where the beam is affected by the coating but is split into parallel sub-paths in a fixed (sample independent) part of the apparatus, components of the beam with different directions of polarization being passed through the sub-paths. A spectrum is determined of ratio's between intensities of the components after they have been affected by the sample, and from the spectrum of the ratio's coating properties are determined. Typically a polarizing splitter is used to split the beam after it has been affected by the sample and the beam is chopped in the sub-paths. After chopping the beam may be recombined before being passed to a detector. The detector may be shared between different arrangements of splitters-choppers-combiners. The beam may be passed to and from the sample through the same splitter.
