49-139 15 mm Dia. N-BK7 Laser Line Window; t=3 mm Laser V-Coat 633nm
The 49-139 is a high-quality Window from Edmund Optics, designed for use in laser applications. This Window features a 15 mm diameter and a thickness of 3 mm, making it a robust and durable option for various setups.
The Window is made from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as BK7, is a borosilicate crown glass that offers low dispersion and low refractive index. It is widely used in the optical industry for its superior performance and reliability.
The Window is coated with Edmund Optics' Las V-Coat 633, a specialized coating designed for use with 633 nm lasers. This coating enhances the Window's performance by reducing reflection and increasing transmission, ensuring optimal laser beam propagation. The coating is applied to both the front and back surfaces of the Window, providing comprehensive protection and enhancement.
The 49-139 is shaped as a Thin Lens, which means it has a curved surface that can refract or focus light. However, as a Window, its primary function is to provide a clear, unobstructed path for the laser beam, rather than to focus or refract the light.
