    摘要: The optical glasses have increased refractive indices and are useful for making space-saving and light-weight imaging optics with lenses of different glass types for use in different objects travelling in space. The optical glasses are suitable for production of optics having low total weight, which is decisive for space applications. These space glasses have high UV- and VIS-transmittance in a range of between 300 and 800 nm and high stability of transmittance over a period of years, because their aging has been greatly limited.

    摘要: The electronic semiconductor component has a crystalline wafer substrate with an active surface and a semiconductor layer coating the active surface. So that the semiconductor layer has a few surface defects the crystalline wafer substrate is a sapphire or silicon carbide single crystal and the active surface has a pit density of less than 500 pit/cm2, preferably less than 100 pit/cm2. The polishing method for obtaining the active surface with these pit densities includes polishing with a polishing agent, such as a silicon suspension, and a polishing tool, which is pressed on the active surface with a pressure of preferably from 0.05 to 0.2 kg/cm2 and moved over the active surface with polishing motions distributed statistically and uniformly over a 360° angle during polishing.

    摘要: In the method and apparatus for measuring the position of the phase interface during growth of a crystal from a melt in a crystal growth container according to the VGF method an incident optical signal is propagated to the phase interface between the melt and the crystal through a window (16) in the container (10) and a received optical signal reflected from the phase interface (14) is measured to determine the position of the phase interface. The position of the phase interface is established from the reflected signal by triangulation with a confocal optic system, by interferometric balancing or by transit time of the optical signal. The window (16) is preferably mounted in a preferably tilted orientation at the end of a tube (15), which is immersed in the melt (12).

    摘要: The method for making a uniform, large-size single crystal of calcium fluoride includes placing a single precursor crystal of calcium fluoride in a tempering vessel provided with a cover; introducing calcium fluoride powder into the tempering vessel and subsequently heating the single precursor crystal, preferably in intimate contact with the calcium fluoride powder, in the tempering vessel together with the calcium fluoride powder for two or more hours at temperatures above 1150° C. to temper the precursor crystal and thus form the uniform, large-scale single crystal of calcium fluoride. The uniform large-sized single crystals of calcium fluoride can be used to make improved lens, prism, light-conducting rod, optical window or other optical component for DUV photolithography, steppers, excimer lasers, wafers, computer chips and electronic devices containing the wafers and chips.

    摘要: The method for determining radiation stability of a crystal to radiation of a working wavelength to be employed in a subsequent application includes taking a first absorption spectrum (A) of a cleaved piece of the crystal with a given thickness (D) over a predetermined wavelength range from a first wavelength (&lgr;1) to a second wavelength (&lgr;2) by means of a spectrophotometer. Then the cleaved piece of the crystal is irradiated with an energetic radiation source so as to form all theoretically possible color centers (saturation). After the irradiating a second absorption spectrum (B) of the cleaved piece of crystal is taken over the same predetermined wavelength range. Then a surface integral of a difference spectrum of the first absorption spectrum and the second absorption spectrum over the predetermined wavelength range is formed and divided by the thickness (D) to obtain a scaled surface integral value. The absorption coefficient &Dgr;k at the working wavelength for the subsequent application is then obtained preferably from the scaled surface integral value for the damage induced by the energetic radiation and a calibration curve relating the absorption coefficient at the working wavelength to the surface integral of the absorption coefficient induced by the energetic radiation.
