Spherical lenses, also known as singlets, are optical lenses with curved surfaces that cause light rays to converge or diverge. They are widely used in imaging applications.What is the power of a spherical lens?Power of a spherical lens can be defined as it’s ability to converge or diverge a ray of…
Concave-convex lens is an important and error-prone knowledge point in junior high school physical optical imaging. Because there are many imaging laws involved in the two, students often confuse them. In this article, we will sort out the structure and imaging of concave and convex lenses. And the…
Underwater photography is an indispensable method for marine research and development and film and television production. However, due to the characteristics of light in water and the particularity of the use environment, glass domes are more and more widely used in underwater optical systems. RZ Op…
