WBMA-30C03-10 30 mm Dia. N-BK7 Round AR coated Flat Window; t=3 mm 633-1064nm

The WBMA-30C03-10 is a high-quality optical window, manufactured by OptoSigma, designed for use in a wide range of optical systems. This window features a base shape of a circle with a diameter of 30 mm, making it suitable for applications where a large aperture is required. The window has a thickness of 3 mm, providing a good balance between mechanical strength and optical performance.

The window is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high transparency in the visible and near-infrared regions. This makes the window ideal for use in applications where high transmission and low absorption are critical, such as laser systems, beam delivery systems, and optical imaging systems.

The window features anti-reflection coatings on both the front and back surfaces. These coatings are designed to reduce reflection and increase transmission, particularly at the design wavelength of 588 nm. The coating specifications are "opt ir1", which is a broadband anti-reflection coating that provides high transmission across a wide range of wavelengths, from 633 nm to 1064 nm. This makes the window suitable for use in multi-wavelength systems and systems where the wavelength may vary.

The window is shaped as a thin lens, which means it has a curvature on both sides. This curvature can help to reduce spherical aberration and improve the optical performance of the system. However, it is important to note that the window does not have any focusing power and is not intended to be used as a lens.
