An illumination system for medical therapeutic and/or diagnostic system is provided. The illumination system includes a laser light source and a light guide. The light guide has a proximal end that is connectable and/or assignable to the one laser light source. The light guide has a distal end with a diffuser element having a radial, spherical emission characteristic. The diffuser element includes a diffuser main body made of an inorganic material, in particular a glass, a glass ceramic, a glass-like substance or a composite substance of the aforementioned substances. The diffuser main body has a scattering element and has a surface that is pore-free and smooth.

A glass laminate for an architectural element has a glass substrate coupled to the architectural element and defines a primary surface facing away from the architectural element. A phase-separable glass cladding is coupled to the primary surface. The cladding has an interconnected matrix with a first phase composition and a second phase that has a second phase composition different than the first phase composition. The second phase is distributed throughout the interconnected matrix. A copper phase is distributed within the interconnected matrix. The glass cladding has an antimicrobial log kill rate greater than about 4 as measured by an EPA Copper Test Protocol.

A magnetic-disk glass substrate containing an alkali metal component as a glass composition includes a pair of main surfaces and an outer circumferential side edge surface that is a mirror surface. The outer circumferential side edge surface includes a surface with a roughness percentage that is 40% or more when a bearing ratio of a roughness cross-sectional area is 50%, in a bearing ratio curve of roughness cross-sectional areas obtained when a surface roughness of the outer circumferential side edge surface obtained by etching the outer circumferential side edge surface by 2.5 μm is measured.

Provided is an antireflective-film attached transparent substrate having a luminous transmittance of 20% to 84% and a b* value of a transmission color being 5 or smaller under a D65 light source, in which the antireflective film has a luminous reflectance being 1% or lower and a sheet resistance being 10.sup.4 Ω/□ or higher, and in which the antireflective film has a multilayer structure built up of at least two layers, at least one layer is constituted mainly of silicon oxide, and at least another layer is constituted mainly of a mixed oxide of at least one oxide of Mo and W and at least one oxide of Si, Nb, Ti, Zr, Ta, Al, Sn, and In, and has an extinction coefficient at 550 nm being in a range of 0.005 to 3.

A method of diffusing one or more of gold nanoparticles, silver nanoparticles, gold ions, and silver ions, into a solid transparent material, causing it to absorb at least some wavelengths of visible light, UV light, or both, the method comprising: (a) providing a first volume of organic solvent with one or more of gold nanoparticles, silver nanoparticles, gold ions and silver ions, blocked with one or more ligands, suspended in the organic solvent; (b) adding a quantity of the volume of organic solvent to a volume of water; (c) immersing the transparent material in the volume of water; and (d) heating the volume of water with the added organic solvent and the transparent material for a period of time, causing the one or more of gold nanoparticles, silver nanoparticles, gold ions and silver ions to diffuse into the transparent material.
