At Tower Optical, we understand that quality is not just a feature—it's a necessity. Our custom circular and square windows are designed 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 transmission, wavelength range, and environmental resistance. We offer a broad selection of materials and anti-reflective coatings to meet diverse needs and specifications.

Our windows are crafted from high-quality materials such as BK7, UV Grade Fused Silica, and Sapphire, with additional materials available upon request. We pride ourselves on offering three distinct quality standards to suit different applications. Whether you require standard, high, or laser-grade windows, our products are manufactured to precise tolerances and specifications, ensuring optimal performance and reliability.

Each window is meticulously crafted to meet stringent dimensional tolerances and surface quality standards. Our commitment to excellence is evident in every product we manufacture, making Tower Optical a trusted partner for all your optical window needs. For custom solutions, we invite you to send us your drawings or specifications, and we will provide a tailored quotation to meet your unique requirements.
