64-048 12.5 mm Dia. N-BK7 Laser Line Window; t=3 mm Laser V-Coat 785nm

The 64-048 is a high-quality optical window, sourced from the renowned vendor Edmund Optics. This window, with a 12.5 mm diameter, is designed for use in laser applications, specifically those utilizing a wavelength of 785nm.

The window is made from N-BK7, a popular glass type known for its excellent optical properties. This Schott glass variant is highly transparent and exhibits low autofluorescence, making it ideal for laser applications. The window has a thickness of 3mm, providing sufficient structural integrity while maintaining minimal optical distortion.

The 64-048 is coated with Edmund Optics' Laser V-Coat, specifically designed for 785nm. This coating enhances the window's performance by reducing reflection and increasing transmission at the specified wavelength. The coating is applied to both the front and back surfaces of the window, ensuring optimal performance from all directions.

The window's geometry is that of a flat window, which is ideal for applications that require minimal optical distortion. The base shape is circular, making it compatible with a wide range of optical systems. The window is designed with thin lens shape, which minimizes weight and potential vignetting.
