HO-WRBB-20-3 20 x 35 mm N-BK7 Flat Window; t=5mm BBAR 400-700nm

This is a rectangular flat window, type HO-WRBB-20-3, manufactured by Holmarc Opto-Mechatronics. The window measures 20 x 35 mm with a thickness of 5mm, making it suitable for various optical applications.

The window is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. It is designed for a wavelength of 632.8 nm, which is commonly used in laser applications.

The window features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces. This coating is designed for a wide range of wavelengths, from 400 to 700 nm, providing minimal reflection and maximizing transmission. The BBAR coating enhances the window's performance in broadband applications, making it an ideal choice for systems that use a wide range of wavelengths.

The window's shape is defined as "Thin Lens", indicating its potential use in lens systems. However, its primary function is to provide a transparent barrier without introducing any optical power or distortion.
