Key Features
These windows are uncoated. AR coatings are available upon request.
UV-grade fused silica is well-suited for applications that benefit from increased transmission deeper into the UV than N-BK7. UV fused silica also offers a lower index of refraction for a given wavelength, better homogeneity, and a lower coefficient of thermal expansion than N-BK7.
N-BK7 provides excellent transmission in the visible and near infrared portions of the spectrum. It is typically chosen whenever the additional benefits of UV fused silica (i.e., good transmission further into the UV and a lower coefficient of thermal expansion) are not necessary.
Meadowlark Optics Optical Windows are top-tier, stress-free optical glass with excellent clarity, making them ideal for precision optical applications.
