HO-WCBC-20-1 20 mm Dia. N-BK7 Circular Flat Window; t=5mm Single Layer MgF2

The HO-WCBC-20-1 is a high-quality circular flat window, offered by Holmarc Opto-Mechatronics, a renowned vendor known for its precision optical components. This window, with a diameter of 20 mm, is designed for use in various optical systems where a clear, undistorted view is required.

The window is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. N-BK7, also known as BK7, is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for a wide range of optical applications.

The window features a thickness of 5 mm, providing a good balance between durability and light transmission. It is coated with a single layer of MgF2 on both the front and back surfaces, which enhances its optical performance by reducing reflection and increasing transmission. The MgF2 coating is known for its high durability and excellent environmental stability.

The window's geometry is defined as a thin lens, indicating its suitability for use in optical systems where precise focusing is required. However, in this case, the window does not alter the path of light, making it functionally equivalent to a flat window.

The window is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website, which is provided in the item data.
