WQK2501 25.4 mm Dia. N-BK7 Precision Round Window; t=6.35mm Uncoated

The WQK2501 is a precision round window, boasting a diameter of 25.4 mm and a thickness of 6.35 mm. This window is made from N-BK7, a high-quality borosilicate glass, which is renowned for its excellent optical properties and is often used in a wide range of optical applications. The window is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

This window is classified as a flat window, which means it does not have any curvature. The flat design is ideal for applications where there is no need for refraction or where the window is used to protect other optical elements. The window's geometry is defined by its diameter and thickness, making it suitable for applications where a specific window size is required.

The window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in applications where coatings are not desired or necessary, such as in applications where the window is used for protection rather than for optical performance.

The window is designed to work at a wavelength of 633 nm, making it suitable for applications that use red light. This could include applications in the fields of spectroscopy, laser technology, or machine vision, among others.
