HO-WCB-20-3 20 mm Dia. N-BK7 Circular Flat Window; t=5mm Uncoated

The HO-WCB-20-3 is a circular flat window, a type of optical window, sourced from Holmarc Opto-Mechatronics. This window, with a base shape of a circle, has a diameter of 20 mm and a thickness of 5 mm, making it a robust and compact option for various optical applications.

The window is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. Schott, a renowned glass manufacturer, produces this specific type of N-BK7 glass. The wavelength for this window is 632.8 nm, which is within the visible light spectrum, often used in laser applications.

The window's shape is that of a thin lens, which is typical for flat windows. This shape allows for minimal distortion and scattering of light, ensuring optimal light transmission. The window is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not limit its usability, as uncoated windows are often sufficient for many applications.
