Holmarc Opto-Mechatronics offers the HO-WCBC-50-3, a circular flat window made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. The window has a diameter of 50 mm and a thickness of 8 mm, making it suitable for various applications.
This window features a single layer of MgF2 coating on both the front and back surfaces. MgF2, or Magnesium Fluoride, is a common anti-reflection coating material known for its low refractive index and high transmission in the visible and near-infrared regions. This coating helps reduce surface reflections, enhancing the window's performance in transmitting light.
The window's geometry is defined as a thin lens, although its primary function is to provide a clear aperture for light to pass through rather than focusing or diverging light like a traditional lens. The window is in stock and available for purchase on Holmarc's website, as indicated by the "weblink status" field in the item data.
