RW-40.0-30.0-5.00-C 40 x 30 mm N-BK7 Laser Grade Optical Window; t=5mm Uncoated

The RW-40.0-30.0-5.00-C is a high-quality optical window, designed and manufactured by CVI Laser Optics. This particular model boasts a rectangular base shape, with precise dimensions of 40 mm in width and 30 mm in height. The window's thickness is a substantial 5 mm, providing excellent structural integrity and durability.

The material used in the construction of this optical window is N-BK7, a type of borosilicate glass manufactured by Schott. N-BK7 is renowned for its exceptional optical properties, making it an ideal choice for laser applications. The window is designed to operate at a wavelength of 633 nm, further enhancing its suitability for laser use.

The window features a flat design, which is beneficial for maintaining the quality of the beam path. The lack of curvature reduces the risk of distortion, ensuring that the beam remains focused and undisrupted. This makes the window suitable for a wide range of applications, including but not limited to, laser cutting, engraving, and medical devices.

Notably, the window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance certain properties of an optical window, such as reducing reflectivity or increasing durability, an uncoated window offers the advantage of maintaining the highest possible optical transmission. This can be crucial in applications where every photon counts.
