BK7 is a very pure optical glass that is used in the production of many Optical components like the optical window and much more. In terms of quality, it’s is top-notch as it is one of the most standard glass types used to produce high-quality optics, mainly for the visible spectrum. The optic BK7 Window is a relatively hard borosilicate material that consists of the purest raw ingredients. It contains very few inclusions and is almost free of bubbles. The high material quality of BK7 is an advantage over a series of other materials and it is a primarily technical reason why the optics BK7 window is often one of the best choices for optical windows, lenses, and prisms. The smooth transmission, as well as a low absorption in the entire visible wavelength range, are a crucial feature for a large number of optical applications. BK7 Is one of the most common and available glasses used to produce high-quality optics widow and another optical component mainly for the visible spectrum.  Optical windows are used to allow optical radiation to safely pass from one environment to another without allowing other elements of these environments to mix either inward or outward. It does not change the wavelength distribution of the beam, the transmitted wavefront, nor does it scatter any of the light rays. The surface specification of the BK7 window is established by the scratch dig. The scratch dig is a pit or small crater on the surface of the glass, is defined by its diameter. The dig number is the actual size of the largest allowable dig, given in hundredths of a millimeter. If a dig is irregularly shaped, the diameter is calculated as half of the length + width of the dig. Both sides of the window have broadband antireflection coatings, which can be used for visible or infrared applications as the choice could be. BK7  is an excellent concave lens convex lens factory  material for most visible and near-infrared applications. It is the most common borosilicate optical glass, which can provide excellent performance at an affordable price. It is a good choice for transmission optics because of its high uniformity, fewer bubbles, low impurities, and easy fabrication which is a known fact. At alpine research optics boulder colorado, we give you the best optics and components you can wish for anywhere.

Features And Properties Of BK7 Windows

• The BK7 window has virtually no bubbles or inclusions and is produced from very pure raw materials
• BK7 windows are suitable for optical applications and can be manufactured with laser-grade precision if need be
• BK7 windows are highly resistant to stains
• Their chemical properties makes them resistant to acid
• Slightly lower resistance to alkali solution
• BK7 Window is made of high quality
• Uniform transmission in the visible as well as into the near-infrared
• They have a very high refractive index homogeneity and a clear
• Almost colorless appearance which makes them the best option for optical applications
• The window is suitable for even high power or UV lasers
• The high surface quality also results in minimum wavefront distortion or light scatter when optical radiation is passed through our windows
• BK7 windows give one of the highest accuracies
