34-246 50 mm Dia. N-BK7 Wedged Window; t=3 mm Uncoated

The 34-246 is a 50 mm diameter N-BK7 Wedged Window with a thickness of 3 mm and an uncoated surface. This window is sourced from the reputable vendor Edmund Optics, and it is currently in stock with a valid weblink for online purchase.

The N-BK7 material, also known as BK7, is a popular choice in the optical industry due to its excellent optical properties. It is a borosilicate crown glass, known for its low dispersion and high transmittance across a wide range of wavelengths, making it suitable for various applications. In this specific window, the material is used in its Schott variant.

The window features a wedge shape, which is characterized by a small angle along one edge. This design is often used to minimize internal reflections or to introduce a known angle into an optical system. The wedge angle in this case is 0.008726646259971648 radians or approximately 0.5 degrees.

The window is circular in base shape, with a diameter of 50 mm. The thickness of 3 mm provides structural rigidity while minimizing unwanted optical effects. The window is uncoated, meaning it does not have any additional layers to enhance or alter its optical properties. This can be beneficial in applications where the natural properties of the glass are desired, or where additional coatings might introduce unwanted complexity or cost.
