39-282 88.9 mm Dia. Float Glass High Efficiency Protective Flat Window; t=1 mm BBAR 425-700nm

This 39-282 optical window, sourced from Edmund Optics, is a high-efficiency protective flat window designed for optimal performance in a wide range of optical applications. The window boasts a generous 88.9 mm diameter and a thickness of 1 mm, ensuring durability and stability while minimizing optical distortion.

The window is crafted from soda lime, a common and versatile material in optical fabrication, known for its high transparency and excellent chemical resistance. The clear variant used here ensures maximum light transmission, making it suitable for applications where clarity and transparency are paramount.

The window features a broadband anti-reflection (BBAR) coating on both the front and back surfaces, specifically designed for the wavelength range of 425-700 nm. This coating significantly reduces surface reflections, enhancing the overall transmission efficiency of the window. It also helps to minimize glare and ghosting, improving the contrast and resolution of the optical system.

The window's geometry is that of a thin lens, which further contributes to its high performance. This shape helps to minimize optical aberrations, ensuring that the light passing through the window remains focused and undistorted.
