37-070 75 mm Dia. N-BK7 Precision Protective Flat Window; t=4 mm VIS 0 425-675nm

The 37-070 is a 75 mm diameter, 4 mm thick Flat Window made from N-BK7 Schott glass. This precision protective window is designed for use in the visible light spectrum, specifically between 425-675nm. The window features a standard antireflective coating on both the front and back surfaces, which is identified as the 'edm vis-0 std curve'. This coating is engineered to minimize surface reflections and optimize transmission within the specified wavelength range. The window's geometry is defined by its thin lens shape, making it suitable for a wide range of optical applications. The window is available from Edmund Optics and is currently in stock.
