AI Thread Summary

Designing a single layer anti-reflection (AR) coating on silicon using magnesium fluoride (MgF2) involves understanding the refractive index calculations. A specific formula, ([n2-n1]/[n2+n1])^2, is used for determining reflectance, but issues arise when plotting results against wavelengths from 300 to 1000 nm. Clarification is needed regarding the discrepancies between the actual and expected results. Providing specific details about the obtained results and the anticipated outcomes will help diagnose the problem more effectively. Accurate plotting and understanding of the refractive indices are crucial for successful AR coating design.

I'm trying to understand how to design a single layer AR coating on Si using MgF2. I know that ([n2-n1]/[n2+n1])^2. But when plotting this against wavelengths 300-1000 on excel I am not getting correct results.

You'll need to be more specific on the problem. What result did you get and what result were you expecting?

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
