Aspects of Camera Lenses: Thickness

There are many types of camera lenses, and the make and material of a particular lens is highly dependent on its use. If you’re talking about lenses, there are different types fitted into different apparatuses such as telescopes, microscopes, specialty cameras and the like. For photography of course, there is a standard imaging lens that is used universally. Aside from the material and type of lens, one factor that contributes to the quality of lens is its thickness. Thickness refers to that space between the front and back surface of the lens. Note that there are several lens glasses built into your camera lens, to prevent any distortion or refraction and to correct your image view.

Thickness in Camera Lenses

In principle, not counting the angle of the lenses’ curvature, the less thickness there is the less distortion is possible. Though it’s not possible for lenses to have nonzero thickness, camera lenses are considered to have non-negligible thickness. Meaning, the thickness of the lenses does not directly affect the image you’re capturing.

Telescopes and microscopes are also considered to have lenses so thin, that they cannot directly refract or distort light. In your photo camera, the lens thickness is so small and insignificant that it’s not what counts for your images; it’s their number and shape that affects what you see through the viewfinder.
