Description
Discover the unparalleled precision and quality of our Fused Silica Precision Optical Flats, expertly crafted to serve as the ultimate reference for determining the flatness of unknown surfaces. These optical components are essential tools in various optical applications, offering exceptional accuracy and reliability. Our optical flats are available in both single-sided and double-sided configurations, providing flexibility to meet your specific needs.
Crafted from high-quality Fused Silica, our precision optical flats boast a flatness specification of λ/10 or λ/20, ensuring superior performance. For less demanding applications, we also offer optical flats made from BK7 material, with a flatness of λ/4 or better. These optical flats are not only functional but also versatile, as they can be used as windows in various optical setups.
Our optical flats are available in a range of diameters from 25mm to 200mm, with precise ground and polished surfaces to ensure optimal performance. The attention to detail in the manufacturing process guarantees that each optical flat meets the highest standards of quality and precision. Whether you require single or dual surface optical flats, our products are designed to deliver exceptional results every time.
At Tower Optical, we understand that quality is not just a feature—it's a necessity. Our commitment to excellence ensures that you receive optical components that are not only cost-effective but also invaluable in achieving precise measurements and results. For custom requirements, we offer tailored solutions to meet your specific needs, ensuring that you receive the perfect optical flat for your application.
