A flat glass is provided that exhibits high transmittance to electromagnetic radiation in a range of wavelengths from 200 nm to 1500 nm. The transmittance for the flat glass having a thickness of 1 mm is 20% or more at a wavelength of 254 nm, 82% or more at a wavelength of 300 nm, 90% or more at a wavelength of 350 nm, 92% or more at a wavelength of 546 nm, 92.5% or more at a wavelength of 1400 nm, 91.5% or more in a wavelength range from 380 nm to 780 nm, and 92.5% or more in a wavelength range from 780 nm to 1500 nm.

Flat glass, method for producing same, and use thereof

A light guide plate for guiding of visible light for the backlighting of a liquid crystal display is provided. The light guide plate has two parallel lateral faces and at least one edge face, which serves preferably as a light input face. The light guide plate is a glass that contains BOand SiOas components, wherein the total content of BOand SiOis at least 70 weight percent and the BOcontent is greater than 10%. The total content of metal oxide of divalent metals in the composition of the glass is less than 3 weight percent. AlOis contained between 1 weight percent and 5 weight percent in the composition.

A device for producing optically homogeneous, streak-free quartz glass bodies having a large diameter including a furnace or melting device having an inner chamber with a pair of openings opposite one another. One or more movable burners are displaceable into one of the openings and the respective glass body to be produced is located in the other opening. Both the burner and glass body are movably positioned. In the course of the production of the quartz glass body, a relative movement is effected in the axial and radial directions between the burner and the quartz glass body such that the distance from the burner outlet opening pertaining to the quartz glass body decreases as the distance from the burner to the X-X axis of the quartz glass body increases.

A plastics comb comprising a center wall and cell walls with normal height at both sides of the center wall is made-up of seveal parts. An injection-moulded center wall and injection moulded cell walls, which are produced separately are connected with each other. The diameter of the cell chamber at the bottom of the cell is larger than that of the cell opening. For breeding queens corresponding combs are provided with a center wall and with cell walls at one side thereof, which are removable from the center wall. The individual cells have cell bottoms, which are entirely or partly exchangeable, for example, as a locking element separate from the cell bottom.
