Scalable aperture-combined optical telescope CSIC and the Astrohita Foundation have developed a telescope, which comprises several optical assemblies that focus the light from a target on individual optical fibers, which are combined together in a final single optical fiber. The rest of the light is simultaneously collected in image devices, which record the field of view of each optical assembly. The gathered images are summed together to achieve a high-quality final image. These telescopes are not of interest only in the field of astronomy but also in the tracking of satellites and space junk. Industrial partners from the Astronomy, Astrophysics and telecommunications sector are being sought to collaborate through a patent licence agreement.

The subject of the offer is new nonlinear optical materials for use in optoelectronics, optical devices and components. The offer relates to co-crystals, from which one of polymorphic form is an efficient, phase matchable second harmonic generator. The averaged, relative experimental of second harmonic generation is over 14 times higher than of the commonly used nonlinear material (potassium dihydrogen phosphate). The presented optical material is colorless, suitable for growing large single crystals. The obtained crystals have extreme values of birefringence with reference to other transparent materials. The maximum birefringence for one of the polymorphic form is 0,46. For comparison, calcite, which is commonly used for the production of polarizing prisms, has a birefringence c.a 0.17. The offered materials, thanks to their properties, may be used for the construction of optical devices and components. Moreover, due to the polar structure may exhibit properties such as pyroelectricity, piezoelectricity or ferroelectricity

New family of dyes The main innovative aspects of this technology regarding current methods of synthesis are: • The indolizine dyes are obtained in one step from commercially available materials, unlike current procedures, which involve multiple steps. This is an advantage in the production process, as it reduces costs, increases the final yield and less waste is generated. • The procedure is based on a very simple treatment which produces indolizine dyes in yields higher than 70%. • The present invention does not require the use of inert atmosphere, dry solvents or physical activation (heat or radiation) to obtain the final product. • Unlike other methodologies for preparing indolizine dyes (requiring temperatures around 100°C), this process is carried out at room temperature and atmospheric pressure, which simplifies the method and decreases production costs. • This is an environmentally friendly technology because it does not use solvents such as dioxane, pyridine, chloroform or benzene, which are used in other methods and are characterized by their high toxicity and demonstrated carcinogenicity. • The selectivity of the reaction is very high. The indolizine dye is obtained with absolute control, obtaining a single isomer of the ten possible.
