Basic principles and classification of optical lenses
The basic principle of optical lenses is to converge or diverge light through the refraction of the lens to form an image. According to the shape and combination of the lens, optical lenses can be divided into the following categories:
Classification by lens shape:
Convex lens: used to converge light, often used to magnify images.
Concave lens: used to diverge light, often used to correct myopia.
Plano-convex lens: one side is flat and the other side is convex, suitable for general imaging.
Bi-convex lens: both sides are convex, suitable for high-precision imaging.
Plano-concave lens: one side is flat and the other side is concave, suitable for diverging light.
Bi-concave lens: both sides are concave, suitable for correcting aberrations.

 

Classification by structure:
Fixed aperture fixed focus lens: the aperture and focal length are fixed, suitable for scenes that require stable light and focal length.
Manual aperture fixed focus lens: the user can manually adjust the aperture, suitable for scenes that require flexible exposure control.
Automatic aperture fixed focus lens: the aperture is automatically adjusted, suitable for environments with large light changes.
Manual zoom lens: Users can manually adjust the focal length, suitable for scenes that require precise control of the focal length.
Automatic zoom lens: Both the focal length and aperture can be adjusted automatically, suitable for shooting in complex environments.
Electric three-variable lens: The focal length, aperture and zoom can all be adjusted electrically, suitable for high-end equipment.
