G390139322 22.4 mm Dia. N-BK7 Optical Flat Window; t=3.5mm 450-700nm

This is a high-quality optical window from Qioptiq Photonics, designed for use in a wide range of optical systems. The window is made from N-BK7 glass, a popular material due to its excellent optical properties and high Abbe number. The N-BK7 Schott designation indicates that this glass meets the rigorous specifications set by Schott, a leading manufacturer of optical glass.

The window has a diameter of 22.4 mm and a thickness of 3.5 mm, making it suitable for use in applications where a thin, lightweight window is required. The flat design ensures that it does not introduce any distortion or aberration into the optical path.

The window is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and improve transmission across the visible spectrum, from 450 nm to 700 nm. This makes it ideal for use in systems where high transmission and low reflection are critical, such as in imaging systems, laser systems, and optical metrology.

The window is available for purchase directly from the Qioptiq Photonics website, where it is listed as in stock. For more information, please refer to the provided weblink.
