    Abstract: An optical device for controlling light from an external light source including: at least a first and a second waveguide for guiding a light beam emitted from the external light source; and at least a first beam shaping structure with a first light emitting area for emitting a light beam and a second beam shaping structure with a second light emitting area for emitting a light beam, wherein the first waveguide guides the light beam emitted from the external light source to the first beam shaping structure and the second waveguide guides the light beam emitted from the external light source to the second beam shaping structure; wherein the first and the second beam shaping structure-are each configured such that the uniformity of the radiant density profile of a light beam emitted from the respective light emitting area of the respective beam shaping structure is higher than that of the light beam guided to the respective beam shaping structure by the respective waveguide. Backlight unit including such an optical device; and optical system, in particular holographic display, including such a backlight unit and a spatial light modulator.

    Abstract: A climate generator adapted to produce a flow of air at controlled temperature and at relative humidity values (tc, ic) is described, which includes a bubbler (100) which receives a flow of air to be conditioned (Ga), heat exchangers (120) associated with the bubbler (100) to adjust the temperature of the water volume (W) of the bubbler and/or to provide an amount of latent heat of evaporation to the aforesaid volume of water (W); and heaters (180) for heating the flow of air at the dew point (Gb) exiting from the bubbler (100) to the controlled temperature value of the flow of air, wherein the temperature of the volume of water (W) is established as a function of the controlled temperature and relative humidity values (tc, ic), so that the heating of the flow of air at the dew point (Gb) from the temperature of the water volume (W) to the controlled temperature value determines a decrease in the relative humidity (ic) of the flow of air to the controlled relative humidity value.

    Abstract: Elastomeric copolymer with a high sulfur content, comprising sulfur in a quantity higher than or equal to 40% by weight, preferably ranging from 55% by weight to 90% by weight, with respect to the total weight of said elastomeric copolymer, and at least one monomer having general formula (I): CH2═CH—(CH2)y-(X)n-(X)m-(CH2)x—CH═CH2 (I) wherein: X represents a sulfur atom, a selenium atom, a tellurium atom, preferably a sulfur atom, a selenium atom; y and x, equal to or different from one another, are a whole number ranging from 0 to 4; n and m, equal to or different from one another, are a whole number ranging from 0 to 3, at least one of n and m being equal to 1; said monomer being present in a quantity lower than or equal to 60% by weight, preferably ranging from 10% by weight to 45% by weight, with respect to the total weight of said elastomeric copolymer; provided that, in the case wherein in said general formula (I) X is sulfur, y and x are 1, at least one of n and m must be different from 1 and the sum of n+m must be different from 1. Said elastomeric copolymer with a high sulfur content can be advantageously used in a great many applications such as, for example, thermal insulation, conveyor
