45-583 50 mm Dia. N-BK7 Precision Protective Flat Window; t=4 mm Uncoated

The 45-583 is a 50 mm diameter, 4 mm thick circular window made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This window, sourced from Edmund Optics, is uncoated, making it suitable for a wide range of applications where anti-reflective coatings are not required.

The N-BK7 Schott glass used in this window is known for its low dispersion and high homogeneity, making it an ideal choice for applications that require high precision and accuracy. The window's thin lens shape further enhances its functionality, making it suitable for use in various optical systems.

The window's geometry, with a 50 mm diameter and 4 mm thickness, provides a good balance between strength and light transmission. The 4 mm thickness ensures the window's durability while minimizing optical distortions. The 50 mm diameter, on the other hand, allows for a wide field of view, making it suitable for use in imaging systems.

This window is designed to work at a wavelength of 587.6 nm, which falls within the visible light spectrum. This makes it suitable for use in applications that involve visible light, such as microscopy, beam delivery systems, and imaging systems.
