At Tower Optical, we understand that quality is not just a feature—it's a necessity. Our custom circular and square windows are meticulously crafted to isolate different physical environments while allowing light to pass through seamlessly. When selecting a window, it's crucial to consider the properties of various optical materials, including their transmission capabilities, wavelength range, and environmental resistance.
