210-0403E 38.1 mm Dia. N-BK7 Flat Round Window; t=3 mm Uncoated

The 210-0403E is a Flat Round Window, offered by EKSMA Optics, with a diameter of 38.1 mm and a thickness of 3 mm. This window is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and high damage threshold.

The window is uncoated, which means it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where the natural properties of the glass are desired, or where cost is a concern. However, it's important to note that uncoated windows can have higher reflectivity, which may not be suitable for all applications.

This window is part of the Flat Round Windows category, which are commonly used in optical systems as protective elements, beam separators, or to change the direction of light. The thin lens shape of this window allows it to be easily integrated into various optical systems.
