Description
Precision Optical Flats are essential components in the world of optics, serving as a benchmark for assessing the flatness of unknown surfaces. Crafted from high-quality Fused Silica, these optical flats are renowned for their exceptional precision and reliability. For applications where less stringent specifications are acceptable, Tower Optical also offers optical flats made from BK7, ensuring versatility and adaptability to various needs.
These optical flats are available in both single-sided and double-sided configurations, providing flexibility for different measurement requirements. The Fused Silica variants boast impressive flatness levels of λ/10 or λ/20, making them ideal for high-precision tasks. With sizes ranging from 25mm to 200mm, these optical flats cater to a wide array of applications, ensuring that you find the perfect fit for your specific needs.
Each optical flat is meticulously ground and polished to ensure the highest quality surface finish. The BK7 options, while more cost-effective, still maintain a high standard of quality, offering a flatness of λ/4 or better. This makes them suitable for less demanding applications without compromising on performance. Whether you require single or dual surface optical flats, Tower Optical provides a comprehensive range of options to meet your precise requirements.
At Tower Optical, quality is not just a promise; it is a guarantee. The precision and craftsmanship that go into each optical flat make them an invaluable tool for professionals in the field of optics. Whether you are conducting research, quality control, or any other application requiring precise surface measurement, these optical flats are designed to deliver unparalleled accuracy and reliability.
