commonly used materials and their optimum spectral regions. The high-indices are 2 (Al2O3 is 1.65) and the low-indices are 1.45. The oxides (except for LaTiO 3) can be sputtered as well as evaporated. Niobia (Nb 2O 5) has become a favored material because it provides higher sputter rates than the other high-index materials. The fluorides used

Overall it has good thermal properties and it is often used for missile domes. It is also birefringent meaning that the refractive index changes with the plane of
Considering 4% loss as normal reflection on fiber tip and 11% (0.5 dB) in connecting multimode fiber to the coupler, the efficiency reduces to 77%. Refractive index of BK7 reduces from 1.5308 at
ited even though alumina is significantly harder than silica-based mate-rials and, as a scratch- and abrasion-resistant filler, higher performance at lower loadings is often observed. For alumina particle sizes greater than 100 nm, the high refractive index (1.72) results in significant light scattering and a hazy appearance in most clear

High-reflective coatings are indispensable in order to manufacture mirrors with highest possible reflectivity. The maximum reflectivity can be achieved by all-dielectric coatings; however, the spectral bandwidth of these mirrors is limited. For astronomical applications metal based coatings (Al, Au, Ag) are commonly applied, as they allow high reflectivity and at the same time a broad spectral
Optical and radiative properties of alumina–silica based ceramic materials are determined in the spectral range of 0.2–2.5 µm. The effects of material thermal treatment on the material structure, composition as well as optical and radiative properties are investigated using the commercial CARBO HSP materials and in-house fabricated samples with sintering temperatures of 1400 ∘ C and

Aiming to characterize the effect of alumina dopant on transparency, powders of yttria stabilized tetragonal zirconia doped with alumina (TZ-3Y-E) are used as starting material to fabricate transparent tetragonal ZrO 2 by high-pressure spark plasma sintering (HP-SPS). However, low transparency of the resultant TZ-3Y-E specimens does not suggest a beneficial effect of alumina

The refractive index of pure alumina is n Alox ’ 1:65 [11] but here alumina is porous so it is neces-sary to calculate the effective dielectric coefficient E eff. Starting point is the Maxwell-Garnett-theorie, which is a good approximation for isolated inclusions [12]. If we assume that E Alox ¼ n2 Alox then the effective dielectric constant
