What is the Fresnel lens ?
Fresnel lens is different from normal lenses, because it is made from concentric annular sections. This way a lens is made of small sections with gaps between them. The more section it has, normally the better it is.
Sometimes curved surfaced can be changed to flat surfaces. So it can be like many prisms focusing in one point.
The new lens is Nikon’s first Phase Fresnel (PF) lens. Nikon used this optical construction in microscopes before.
High quality Fresnel lenses were commonly used in lighthouses in the 19th and 20th century.
Plastic Fresnel lenses were sold as a sreen in front of the TV screen for enlarging the image of the television.
Nikon also used a Fresnel lens in a compact camera teleconverter, the Nikon TC-E3PF for a Coolpix 8400 camera, the converter is no longer available.
