64-040 20 mm Dia. N-BK7 Laser Line Window; t=3 mm Laser V-Coat 405nm

The 64-040 is a 20 mm diameter N-BK7 laser line window, featuring a thickness of 3 mm and a laser V-coat optimized for 405nm. This component is sourced from the reputable vendor, Edmund Optics.

As a window, this optical element is designed to maintain the optical path of a beam without introducing any additional optical power. This particular model boasts a flat window design, ensuring minimal distortion and maintaining the beam's original profile. The window's base shape is circular, contributing to its versatility and wide range of applications.

The window is constructed from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and high damage threshold. This material, also known as Schott BK7, is a borosilicate crown glass, characterized by its low dispersion and high homogeneity.

The 64-040 is specifically designed for laser applications, as evidenced by its 405nm wavelength optimization. This makes it an ideal choice for systems operating in the blue region of the spectrum.

The window's coating further enhances its suitability for laser applications. Both the front and back surfaces are treated with an Edmund Optics Las V-coat, designed explicitly for 405nm. This coating is engineered to reduce reflection and enhance transmission, thereby improving the system's overall efficiency and performance.

The window's geometry, defined by its 20 mm diameter and 3 mm thickness, contributes to its robustness and durability. This makes it suitable for use in various environments, including those subject to mechanical stress or temperature fluctuations.
