Description
Precision optical flats are essential components in the field of optics, providing a reliable reference for determining the flatness of unknown surfaces. These high-quality optical flats are crafted from Fused Silica, a material renowned for its exceptional optical clarity and thermal stability. For applications where less demanding specifications are acceptable, Tower Optical also offers optical flats made from BK7 glass, ensuring versatility and accessibility for various needs.
The precision optical flats are available in both single-sided and double-sided configurations, catering to a range of measurement and application requirements. With flatness specifications of λ/10 or λ/20, these optical flats ensure superior accuracy and performance. The use of Fused Silica not only enhances the optical properties but also provides excellent resistance to thermal expansion, making these components suitable for use in environments with fluctuating temperatures.
Available in diameters ranging from 25mm to 200mm, these precision optical flats are meticulously ground and polished to meet stringent quality standards. The attention to detail in their manufacturing process guarantees a surface quality of 60/40 and parallelism of less than 1 arc minute, ensuring reliable and repeatable measurements. Whether used as a reference surface or as optical windows, these precision optical flats offer unmatched quality and performance, embodying the principle that quality is not expensive, but priceless.
