Increasing the numerical aperture of an optical system may increase the resolving power, but it’s not a foolproof way to improve performance.
Application of DLC film: Diamond-like hardness, corrosion resistance, and high transmittance make DLC ideal for enhancing infrared lenses.
Key Takeaways: The paraxial approximation simplifies optical calculations by assuming small angular deviations, useful for systems like lasers and optical fibers. It’s accurate for angles under 10 degrees, where errors are less than 0.5%, but fails at larger angles, requiring more precise methods. For waveguides with small effective mode areas or strong focusing systems, the […]
