HO-WCB-25-3 25 mm Dia. N-BK7 Circular Flat Window; t=6mm Uncoated

The HO-WCB-25-3 is a 25 mm diameter Circular Flat Window made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This window, offered by Holmarc Opto-Mechatronics, has a thickness of 6mm and is uncoated, making it suitable for a wide range of applications.

The window's geometry is defined by its diameter and thickness. With a diameter of 25 mm, it provides a substantial aperture while maintaining a compact form factor. The 6mm thickness offers rigidity and durability, making it suitable for use in various environments.

The N-BK7 material, also known as Borosilicate Crown, is known for its low coefficient of thermal expansion and excellent transmission properties in the visible and near-infrared regions. This makes the HO-WCB-25-3 ideal for applications that require high optical quality and precision.

The window is designed in the shape of a thin lens, which is a simple optical element that alters the direction of light passing through it. However, as an uncoated window, it does not have any anti-reflective or other surface coatings. This may result in some light being reflected at the air-glass interfaces, but it does not affect the window's optical quality or performance.
