    Lens Reflection
AI Thread Summary
Light does indeed reflect off the surface of a lens, with the amount of reflection influenced by the angle of incidence and the presence of anti-reflection coatings. When total internal reflection occurs, no light propagates through to the other side of the lens. This phenomenon confirms that total reflection means complete reflection without transmission. Understanding these principles is crucial for applications involving lenses in optics. The discussion emphasizes the importance of lens design in managing light behavior.

When a passing through a lens,will there any reflection on the surface of it?
 
Science news on Phys.org
Absolutely. The amount of light reflected from the surface depends on the angle of incidence along with other factors such as whether the lens has any anti-reflection coatings or not.

Thanks.And I want to ask if there any light propagate to the other side of the lens when total internal reflection occurs?

No. Total reflection really is total

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...
