64-042 30 mm Dia. N-BK7 Laser Line Window; t=4 mm Laser V-Coat 405nm

The 64-042 is a high-quality optical window, specifically designed for use with laser systems operating at a wavelength of 405nm. This window is manufactured by Edmund Optics, a leading provider of optical components, ensuring reliability and performance.

The window features a base shape of a circle with a diameter of 30mm, providing a large aperture for laser beam transmission. The thickness of the window is 4mm, offering a good balance between mechanical strength and optical performance. The material used for the window is N-BK7, a type of borosilicate glass known for its excellent optical properties, including high transmission in the visible and near-infrared regions, low autofluorescence, and excellent homogeneity.

The 64-042 window is coated with Edmund Optics' Laser V-Coat 405nm on both the front and back surfaces. This coating is specifically designed to enhance the performance of laser systems, providing high transmission at the design wavelength and excellent environmental resistance. The coating also helps to reduce reflections, improving the overall efficiency of the system.

The window is shaped as a thin lens, which means it has a very low curvature, making it suitable for use in applications where flatness is critical. This window is currently in stock and available for immediate shipping, making it an ideal choice for researchers and engineers who need a high-quality optical window for their laser systems.
