Principle:

The top of the object is also used as two straight lines: one is parallel to the main optical axis and is deflected into a divergent light after passing through the biconcave lens, returning this refracted light to the main focus in the opposite direction; the other passes through the optical center point of the lens, these two lines The straight lines intersect at one point, this is the image of the object.

 

Application:

The main applications of biconcave lenses: optical imaging, astronomical observation, scientific research, military industry and other precision instruments.
