W-BKP002 12.5 mm Dia. N-BK7 Precision Flat Window; t=1mm Uncoated

The W-BKP002 is a precision flat window, part of the extensive optical components catalog provided by Ross Optical. This component, with a base shape of a circle, has a diameter of 12.5 mm and a thickness of 1 mm, making it a thin and lightweight option for various optical applications.

The window is made of N-BK7, a type of borosilicate glass developed by Schott AG, known for its excellent optical properties. N-BK7 is a crown glass with a low refractive index and low dispersion, making it an ideal choice for applications that require high optical quality and precision.

The W-BKP002 is designed for use at a wavelength of 633 nm, which is within the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging systems, beam delivery systems, and other optical instruments.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be beneficial in applications where the natural properties of the glass are desired, or where additional coatings may interfere with the system's operation. However, it's important to note that uncoated windows may have higher reflectivity and may not perform as well in high-precision applications compared to coated windows.
