Sapphire Diamond White

What is the substance most perfect lens to a telescope?

High transparency. High refractive index. Low dispersion spectral. Assume that cost is not a consideration. A kind of glass? white sapphire? Diamond? a kind of tourmaline? transparent quartz? minerals? Plastic high refraction? starrysky, many minerals can be synthesized in bulk. Sapphire, corundum alias, alias Al ₂ O ₃, is one of them. Others are silicon carbide (SiC Moissanite), zirconium dioxide (ZnO ₂) and silicates (quartz, SiO ₂). I think even diamond can be synthesized in quantity. They all have optical properties (refractive index and dispersion), even if all can not exist in wavelengths very transparent visible.

First, it must be obtained in size - leaving aside the most precious stones. In addition, the Most of them have inclusions, defects and variations in refractive properties. Then it must be compatible with other materials. Omission of the most toxic substances or corrosives. Then it must be designed for specific wavelength. Ultraviolet light is transmitted by quartz. The infrared is transmitted by the zinc selenide. Visible light is transmitted through glass, plastic, glass different salt. And to avoid aberrations of the objective of the final image, multiple lenses are used, with slight variations from one lens to another be checked accurately. These lenses can be carefully designed in the team to know the refractive indices of human many glasses. Corona, stone, ED and fluorite lenses regularly agreements are presented in a very good lens. See Televue, Zeiss, Takahashi, Astro-physics, TMB and the quality of many other manufacturers of lenses, telescopes, cameras and microscopes.

Finger Lakes wineries in Florida successfully in the "In general, the quality of wines (sparkling) is done here is excellent," Swedish Hill Owner Dave Peterson said today, adding that the history of the Finger Lakes "to make sparkling wine goes back to the years 1800.
