All about flat optics

1. All about flat optics http://www.lagauge.com/

2. Flat Optics is specifically polished and flattened surfaces. They are often used as a reference to assess the flatness of unknown surfaces. The principle method by which an optical flat functions is as follows: • Contact is made between the polished surface and the surface of unknown flatness. • Under monochromatic light, dark and light bands (interference fringes) form and can be seen. • The shape of these interference fringes depicts the visual illustration of the flatness of the unknown surface. • The surface accuracy is estimated through the amount of spacing between the fringes as well as their curving. • A surface with parallel, straight, and evenly spaced fringes is indicative of being more flat or equally flat as compared to the reference surface. http://www.lagauge.com/

3. Applications of Flat Optics • These versatile optical devices have multiple uses, such as: • Measuring the flatness of polished work surfaces • Inspecting gauge blocks for accuracy and optimal working capacity • Windows that require specific interference and reflection • Materials for Flat Optics • Fused Silica • Very low thermal expansion • Extremely durable • Highly resistant to abrasions http://www.lagauge.com/
