N-BK7 Wedged Windows are precision optical components engineered with a small wedge angle between the two surfaces. This geometry prevents parallel reflections, reducing etalon effects and ghost images that can interfere with system accuracy. As a result, these windows are essential in laser cavities, imaging paths, and sensitive measurement instruments.
Band Optics manufactures N-BK7 Wedged Windows for OEMs, research institutes, and system integrators who require consistent optical performance and mechanical reliability. N-BK7 glass is widely selected for its excellent homogeneity, transmission, and cost efficiency in visible and near-infrared applications. All products follow a custom optics wholesale model to ensure each window meets exact system specifications.
Customers working directly with Band Optics through www.band-optics.com receive engineering support from design validation to volume production.
The controlled wedge angle in N-BK7 Wedged Windows separates secondary reflections from the primary optical path. This significantly improves signal quality in interferometry, laser alignment, and imaging systems.
N-BK7 offers high transmission, low bubble content, and stable refractive index properties. These characteristics make N-BK7 Wedged Windows suitable for precision optical assemblies requiring predictable behavior.
As a custom optics wholesale manufacturer, Band Optics supports a wide range of diameters, thicknesses, and wedge angles. This flexibility allows N-BK7 Wedged Windows to integrate seamlessly into custom optical designs.
Optical blanks are cut and ground to achieve the specified wedge angle. Angular tolerances are tightly controlled to ensure consistent beam separation.
Advanced polishing processes deliver smooth surfaces and accurate flatness. Each N-BK7 Wedged Window is inspected to meet defined surface quality standards.
Band Optics supports prototype development, small-batch orders, and large-scale manufacturing. Production workflows are optimized for reliability and repeatability within custom optics wholesale supply chains. Additional details are available at www.band-optics.com.
