W hat are witness samples Coating on different optical surfaces, including spherical, aspherical, planar, etc., but how to better detect the performance of thin film? The usual landscape photometer detection systems are suitable for plane detection, from which the witness samples are derived. Through the witness sample, the transmittance, reflectivity, actual applicable temperature, moderate and so on of the film can be detected.   DESCRIPTIONS   Descriptions of Witness Samples The witness samples provided by Ecoptik China include a full range of brands such as CDGM, Schott, CORNING, etc. The general diameter is about 1'' and the thickness is 1-3mm, which basically adapts to the size of standard spectrophotometer tools.   Ecoptik China witness samples be polished one side or both surface according to the customers' requirement to be used meet for transmit or reflect thin film coating.   SPECIFICATIONS   Specifications of Witness Samples There are many optical co...

A dielectric mirrors  also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material. By careful choice of the type and thickness of the dielectric layers, one can design an optical coating with specified reflectivity at different wavelengths of light. Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser. Mirrors of this type are very common in optics experiments, due to improved techniques that allow inexpensive manufacture of high-quality mirrors. Examples of their applications include laser cavity end mirrors, hot and cold mirrors, thin-film beamsplitters, and the coatings on modern mirrorshade...
