New approaches to High-Power LED Clusters Cooling The arrangement based on the rule “crystal glass in front, heat sink behind” is implemented in the absolute majority of LEDs constructions. Such an arrangement completely justified itself for the previous generation of low-power LEDs. But this cooling method turned out to be clearly insufficient for modern high-power LED clusters. The problem of excessive heat removal from LED crystal becomes critically important

To the History of Modern Optics and the Role of Vavilov State Optical Institute in its Development in Russia. Part II Optical processes have been interesting people for many centuries and millenniums, however, the practical achievements in optics are actually 400–500 years old. In December 1918 in Petrograd was established the State Optical Institute (SOI) and within three years it will be 100 years old. The second part of the review of optics history is dedicated to the institute birth and establishment of its traditions.

Surprises of Medium-Wave IR LEDs Based on А3В5Heterostructures The specific properties of medium-wave LEDs, which are absent for the "common" visible band LEDs for example, negative luminescence and thermoelectric excitation are considered. Analysis of such properties in respect to the instrument engineering is performed.

Apparatus for Electrooptical Measurement and Control of Components of Power Reactors Fuel Assemblies The technology of producing items by welding includes the operations of control of permanent joints on a mandatory basis. If there are elements with the complex shape surfaces incorporated in the items, the precision of their execution is determined using special measurement means –contact measurement devices. The article covers the control of welded joints of spacer grids and slab lattices of VVER power reactors fuel assemblies (FA).
