G390137329 20 x 30 mm N-BK7 Optical Flat Window; t=2.5mm 1064nm

The G390137329 is a high-quality optical flat window, measuring 20 x 30 mm, manufactured by Qioptiq Photonics. This window is designed for use in a variety of optical systems, offering excellent transparency and durability.

The window is made from N-BK7, a popular type of borosilicate glass known for its excellent optical properties. This material is characterized by a low coefficient of thermal expansion, making it resistant to thermal shock and suitable for use in a wide range of temperatures. The window has a thickness of 2.5mm, providing a good balance between strength and light transmission.

The window features anti-reflective coatings on both the front and back surfaces. These coatings, specifically the Qio HP Nbar ARHS-YAG coating, are designed to minimize reflection and increase transmission at a wavelength of 1064nm. This makes the window ideal for use in systems that operate at this wavelength, such as Nd:YAG lasers.

The window is rectangular in shape, with dimensions of 20 x 30 mm, providing a large aperture for light transmission. The window is also thin, with a shape described as "Thin Lens", which minimizes optical aberrations and ensures that the window does not significantly alter the beam path.
