Questions about Optical Systems: 1. How do different refractive indices affect the performance of optical systems? 2. What are the key factors to consider when designing optical systems for various applications?
1. A relevant generic question not answered by the article, with a detailed answer. How does the combination of positive and negative focal power lenses contribute to the overall optical performance of the system? When positive and negative focal power lenses are combined in an optical system, they work together to correct aberrations and improve image quality. The positive lens converges light rays, while the negative lens diverges them, resulting in a more precise focus and reduced distortion.
2. Another relevant generic question, with a detailed answer. What role does the refractive index play in the functionality of optical lenses? The refractive index of a lens determines how much light is bent as it passes through the lens. A higher refractive index means light travels slower through the lens, affecting the lens's focal length and overall optical performance. By carefully selecting lenses with specific refractive indices, optical systems can achieve desired magnification and clarity.
Original Abstract Submitted
an optical system has an optical axis, and includes a positive focal power lens, a negative focal power lens and a display. the positive focal power lens includes a first convex surface away from the display and a second convex surface proximate to the display. the negative focal power lens includes a third convex surface away from the display and a fourth concave surface proximate to the display. for a refractive index of the positive focal power lens and a refractive index of the negative focal power lens, one is greater than another, and a greater refractive index is a first refractive index, a smaller refractive index is a second refractive index, the first refractive index is greater than 1.7, the second refractive index is greater than 1.5, and a ratio of the first refractive index to the second refractive index is less than or equal to 2.
