Identifying Key Factors towards Highly Reflective Silver Coatings

Silver-based reflective coatings for micromachined optical filters

Silver films of 40 nm thickness, evaporated on a 300 nm thick low-stress silicon nitride layer, are used as high-quality mirrors operating in the visible and near IR spectral range. Using a silicon nitride membrane under tension, within a square Si frame after bulk micromachining, improves the initial mirror flatness. Two parallel mirrors, with square aperture of up to 2x2 mm and an electrostat...

Identifying and Analyzing Key Factors Affecting Singleness in Iran

In the past decades, social structures and institutions, including families, have been transformed by phenomena such as modernism, globalization and the expansion of communication networks. Transformation in the pattern of marriage and the age of marriage is one of the domains affected by these changes. In Iran, delay in marriage and increased Singleness have increased in recent years. The pur...

Identifying key factors affecting transnational knowledge transfer

Wewished to further understand Transnational Knowledge Transfer (TKT) in a not-for-profit context. To accomplish this, we explored, verified, and mapped out the key factors affecting TKT using a fourcomponent framework in the context of publically funded knowledge transfer (KT) projects. The Delphi technique was used to explore, identify, and verify the relevant key factors; 24 major factors we...

Abrasion Resistant Anti-Reflective Sol-Gel Coatings

Many optics in both the OMEGA and OMEGA EP lasers are coated with anti-reflective (AR) silane sol-gel to maximize their transmittance. Although these coatings are highly resistant to both airborne contaminants and laser damage, they are susceptible to mechanical damage by abrasion, and thus require extra care during the handling, installation and alignment of sol-gel optics. Previous “hardened”...
