Hangzhou Shalom Electro-optics Technology Co., Ltd. BK7 λ/10 D50.8x12mm Uncoated Windows or Substrates 132-025

Features: • Made of N-BK7 • High scratch-resistance • Stable chemical properties • Stocked and Custom Products • Excellent as windows or mirror substrates Optical windows are used to transmit light and protect work areas or sensitive components from the outside environment. Optical windows use substrates, coatings, or a combination of the two to transmit specific wavelengths or ranges of wavelengths. Uncoated N-BK7 windows could also be used as substrates or blanks of mirrors. N-BK7 features excellent transmission from visible to NIR spectrum, low inclusion of bubbles and impure substance, and ease of manufacturing and machining. Therefore it is an excellent choice for transmission optical components. As mirror substrates, N-BK7 is also advantageous in terms of fine mechanical properties and resistance to scratches, and stable chemical properties. However, it possesses high coefficients of thermal expansion in relative, thus not appropriate for environments where temperatures are changeable. Shalom EO’s stocked N-BK7 windows or mirror blanks including the Lambda/4 flatness modules and lambda/10 modules, while Lambda/4 flatness is low cost and suitable for most kinds of optical applications, and the Lambda/10 flatness modules are suitable for laser system and other high demanding applications.
