62-608 75 mm Dia. N-BK7 Precision Protective Flat Window; t=4 mm MgF2 400-700nm

This 75 mm diameter, 4 mm thick N-BK7 window is a precision protective flat window, coated with MgF2 for wavelengths between 400-700nm. Sourced from Edmund Optics, this window is a flat, circular optical component designed for use in a variety of applications.

The window is made from N-BK7, a popular glass type known for its excellent optical properties, making it suitable for use in high-precision applications. The window's geometry includes a diameter of 75 mm and a thickness of 4 mm, providing a robust and stable platform for optical systems.

The window's coating is a standard MgF2 coating, applied to both the front and back surfaces. This coating is designed to provide high transmission across the specified wavelength range, enhancing the window's performance in its intended application.

The window's shape is that of a thin lens, although it does not possess any focusing or diverging properties. This shape is typical for flat windows, which are designed to protect optical systems from environmental hazards without affecting the system's optical properties.
