G390135000 63 mm Dia. N-BK7 Optical Flat Window; t=6mm Uncoated

The G390135000 is a 63 mm diameter N-BK7 Optical Flat Window with a thickness of 6mm, sourced from Qioptiq Photonics. This window is a type of optical element designed for use in various applications where the transmission of light needs to be maintained with minimal distortion.

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, which reduces the risk of thermal stress and maintains the optical integrity of the system. The specific N-BK7 Schott variant used in this window ensures a high level of consistency and quality.

The window is flat, meaning it does not have any curvature. This is ideal for applications where a flat optical surface is required, such as in beam splitters, filters, or as a protective cover for optical components. The window is also uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where the natural properties of the glass are desired.

The window is 6mm thick, providing a good balance between durability and light transmission. Thicker windows offer more protection for the optical components they cover, while thinner windows allow for more efficient light transmission. The 6mm thickness of this window provides a good compromise between these two factors.

This window is designed for use at a wavelength of 633nm. This makes it suitable for a wide range of applications, including laser systems, spectroscopy, and interferometry.
