Description
Precision Optical Flats are essential components in the field of optics, offering unmatched accuracy and reliability. Crafted from high-quality Fused Silica, these optical flats serve as a reference standard for determining the flatness of unknown surfaces. Their exceptional flatness, specified as λ/10 or λ/20, ensures precise measurements and evaluations. For applications with less stringent requirements, Tower Optical also provides optical flats made from BK7, which offer a flatness of λ/4 or better. These versatile components can also function as windows, making them a valuable addition to any optical setup.
Available in both single-sided and double-sided configurations, Precision Optical Flats are designed to meet a wide range of needs. Their ease of use and adaptability make them suitable for various applications, from scientific research to industrial quality control. With diameters ranging from 25mm to 200mm, these optical flats are precision ground and polished to deliver the highest level of performance. The choice of material, either Fused Silica or BK7, allows users to select the best option based on their specific requirements and budget.
At Tower Optical, we understand that quality is not just a feature—it's a necessity. Our commitment to excellence ensures that each optical flat meets rigorous standards for surface quality, parallelism, and dimensional tolerances. Whether you need a standard product or a custom solution, our team is ready to assist you. We offer custom versions of all our products, tailored to your drawings or specifications, ensuring that you receive the perfect optical component for your needs.
