It's a very new idea - I think that it should be mentioned.
From the scientific american article on the topic, I believe it was reproduced. 69.255.20.212 23:10, 15 June 2006 (UTC)
There are some skeptical reviews of the work: http://arstechnica.com/science/news/2008/08/first-superlens-not-so-super-yet.ars DonPMitchell ( talk) 15:30, 22 May 2009 (UTC)
I'm more than skeptical! Some of what is contained in the article is valid (such as super resolution with the tiny holes) but the main subject of the Pendry lens using a supposed (but impossible) negative index of refraction material is not physically realizable. Please see my comments at [1] Interferometrist ( talk) 20:55, 28 February 2010 (UTC)
Sorry, that didn't come out right (I'm new to editing WP!). I was trying to reference my comments on the talk page about negative index of refraction materials at: http://en.wikipedia.org/wiki/Talk:Negative_index_metamaterials#Not_valid_science Interferometrist ( talk) 20:58, 28 February 2010 (UTC)
The diagram I added isn't by means precise (not really sure how to make perfect ray diagrams), but I think it gives a good idea on how the focusing works.
I think focusing the article on Pendry's lens will make it more clear, as it seems to be the thing most popularly referred to as a superlens. Pyjeon ( talk) 14:07, 1 June 2009 (UTC)

I came here to find out how a superlens works. I'd like to be polite, but I'm very frustrated. I've read many times now about how conventional lenses are used to visualize cells -- like four times -- along with several descriptions of why conventional lenses can't make clear images of things smaller than the wavelength of light that they focus. Get to the point!
Then when it seems like the author is about to describe how a superlens works, he or she just drops jargon. It uses near-field electromagnetic waves, rather than far-field! It's a metamaterial! There's a layer of gold atoms! But never mind how that allows better resolution! Because metamaterials!
Please, just a layperson's description of how it works. Without a 5,000-word preamble about conventional lenses, analogies about pencil-line widths, and stuff about staining biological cells. — Preceding unsigned comment added by 144.191.148.3 ( talk) 20:52, 3 October 2013 (UTC)
The Superlens article is a carefully compiled collection of inventive speculations on the subject of bypassing the clasical physical limits of Newtonian optics and Maxwell's electromagnetic wave equations.
The rhetorical appeal of the article comes from the fact that every student who has looked through a microscope has experienced the ambiguity and blurring of images visible in the instrument. Instead of a super lens, accurate observation and discovery requires years and careers and a wide variety of inductive and deductive experimentation.
Previous Editing Talk writers have called for substantial editing. I suggest "Superlens" should be edited to make it clear it is a story of a succession of inventors who have tried to bypass the limits of physical optics. Then the article can be organized into efforts at bypassing the Rayleigh criterion, changing the wavelength of the light source, surface profiling with electron probes, and decoupling the Maxwell field symmetries.
All the super lens stories end in the same way, the experimental setup does something interesting but there is a lot of noise in the data or the next generation of apparatus can't quite be built. In a way, the super lens idea is to biology as the 100 MPG carburetor story is to the car industry and the perpetual motion machine was to the 18th century steam engine business.

I corrected the text for the figure by adding the 'a) ', but the figure in 'a' is incorrect. The right hand arrow in the blue normal material should be closer to the normal than the incident ray. Perhaps make the normal material a different color to set it apart. -- Steve -- ( talk) 04:37, 11 December 2015 (UTC)

This article is quite frustrating to read. It has way too many titles and too less actual content. Sometimes it isn't even clear which title is over which sub-title. The article is basically written as a list of achievements instead of as an explanation of the subject. While achievements are valid in a wikipedia article, they should not come instead of the explanation. 185.175.35.246 ( talk) 05:48, 28 September 2020 (UTC)
