This is a rectangular flat window, HO-WRBC-30-1, offered by Holmarc Opto-Mechatronics. The window measures 30 x 50 mm and has a thickness of 8mm, making it suitable for various optical applications.
The window is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. Schott is the manufacturer of this particular N-BK7 glass. The window's design is based on the thin lens shape, which is often used in optical systems to minimize aberrations and distortions.
The window features a single layer of MgF2 coating on both the front and back surfaces. This coating, provided by Holmarc, is designed to reduce reflection and increase transmission, enhancing the window's performance in its intended application. The coating is applied at 0 AOI (Angle of Incidence), ensuring uniformity and consistency.
