64-039 15 mm Dia. N-BK7 Laser Line Window; t=3 mm Laser V-Coat 405nm

The 64-039 15 mm Dia. N-BK7 Laser Line Window is a high-quality optical component designed for use in laser applications. This window, sourced from Edmund Optics, features a 15 mm diameter and a thickness of 3 mm, making it suitable for a wide range of applications.

The window is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The N-BK7 Schott designation indicates that this particular glass meets the stringent quality standards set by Schott, a leading manufacturer of optical glass.

The 64-039 window is coated with Edmund Optics' Laser V-Coat 405, a specialized coating designed to enhance its performance in laser applications. This coating is applied to both the front and back surfaces of the window, providing optimal protection and performance. The Laser V-Coat 405 is specifically designed for use with 405 nm lasers, ensuring optimal performance in this wavelength range.

The window is shaped as a thin lens, which can be beneficial in certain applications due to its reduced weight and potential for reduced aberrations. Despite its thin shape, the window maintains the excellent optical properties expected from N-BK7 glass and the Laser V-Coat 405 coating.
