Here are some more information for Micro Lens:

The following article provides a guide on how to compare plasma LCD and rear projection HDTVs, including the differences between the technologies used in each.
Many people are confused by words in the electronic industry today such as "rear projection television", "plasma", and "LCD flat panel". In order to understand exactly what you are buying when you purchase one of these items, you must first understand the underlying technology behind each one.
You must know whether wide screen televisions are better than regular flat screen televisions, and whether plasma screens are better LCD screens. The difference between LCD rear projection and flat panel sets is also important.
Before you purchase one of these electronic items, you should first understand exactly what their names mean so that you will not become confused by the salesman at your local electronics store. You will then be able to decide what is worth your money and what is not.
The following are several short introductions to each of these technologies used in modern televisions.
Rear Projection Television: These televisions involve a lamp behind a screen which projects an image onto the screen. This technology is also known as micro display, and is different from the more traditional CRT, or cathode ray tube, technology used in older televisions.
There are three different types of micro display - namely Liquid Crystal Display (LCD), Digital Light Processing (DLP), and Liquid Crystal on Silicon (LcoS). While televisions that use micro display technology are flatter and lighter than televisions that use CRT technology, the lamps in micro displays have to be changed once every two or three years.
Plasma Television: These televisions are almost always in the form of a flat panel, as they use technology that enables manufacturers to house the required electronics in a flatter panel.
A plasma television's display works in much the same way as a fluorescent lamp, consisting of two glass panels containing xenon gas between them. The gas, in the form of plasma, is injected and then an electrical charge is run through, causing it to light up in reds, blues, and greens, thus creating an image. Each pixel consists of red, blue, and green phosphors.
Traditional CRT televisions, however, contain a vacuum tube, which emits an electric beam across the surface of the tube, lighting up the phosphors. Thus these displays are larger than the modern ones.
Liquid Crystal Display Televisions
LCD rear projecting systems are not the same as LCD flat panel televisions, as rear projection LCD televisions create an image by projecting light through a transparent LCD chip, which consists of individual pixels displaying the moving video images, thus projecting the image forward through a lens that magnifies the image, onto a mirror, which finally reflects the image onto the screen.
The chip used in a rear projection television is extremely small and thus is extremely light, taking up much less space than the cathode ray tubes in more traditional televisions.
While LCD rear projection televisions are not as compact as plasma or LCD flat panel televisions, they are still much smaller than conventional televisions. These televisions are also less expensive as compared to plasma and LCD flat panel televisions, and they also have wider screens. LCD rear projection systems also provide brighter images and greater contrast.
This short introduction to HDTV technology should be of some use to you if you wish to compare plasma LCD and rear projection HDTVs. You should compare aspect ratio, screen size, resolution, HDMI interface, and price when selecting a television. You should also make a comparison between similar television models from different brands, as they may be different.

Steps for cleaning and disinfecting a contact lens
The invention of contact lens is one of the best inventions in human history. Contact lens was discovered in 1887, but it was not used at that time. At that time, contact lens were made of thick glass, as a result it was very difficult for the people to use it. Later, with advancement of technologies, contact lens became wearable. Nowadays, people prefer contact lens more than spectacles. Carrying a spectacle on their ears all day long is often a problem for hard working people and also for the young kids. For this kind of reason, people tend to use contact lens more than spectacles.
However, there are some problems about the contact lenses. Most importantly, it has to be cleaned regularly. Most people do not take much care of their lenses and are ignorant about it. There are several different options for cleaning and disinfecting a contact lens, depending on the type of lens a person is wearing. Not cleaning a contact lens regularly can cause discomfort and reduce vision and even contamination. However, contact lens cannot be cleaned like the glass spectacles; it should be cleaned very carefully. There are also certain limitations for cleaning a lens.
Firstly, contact lenses cannot be cleaned by water. This is because normal water contains various minerals, metals and also micro organisms which can cause infection to the human eye. Purified water also cannot be used for such purpose as it cannot disinfect a lens. The best way to clean contact lenses is using the solutions provided with the lens. These solutions are made in such a way, that not only it can clean and disinfect the lenses, but also protect a person’s eyes. The solution prevents the lens from drying up and gives comfort for long time. This solution even works as a good disinfectant for the contact lenses.
People should always choose solutions keeping in mind the following:
1.The solution should keep the contact lens lubricated which will give you relief from dry, irritated eyes.
2.The solution should lubricate a contact lens in such a way that it can give one relief from irritations caused by dirt, smoke or dryness.
3.The solution must help free movement of the contact lens.
4.The solution must be suitable for all kinds of lenses, even the gas permeable contact lenses.
If you have contact lenses, certain things should be kept in mind.
1.It should be cleaned very carefully and with soft cloth, so that it doesn’t get a single scratch. A single small scratch can spoil the lens.
2.It should be stored in a saline solution.
3.Cleaning and disinfecting is a must, proper disinfecting will kill the micro-organisms which are responsible for infections.
There are many options for cleaning and disinfecting a lens depending on the kind of lens a person is using. The daily disposable contact lenses do not have to be cared much.
However, the permanent contact lenses need a lot of attention and care. Negligence can spoil it and can also cause problems to your eyes.

Best close focusing micro/macro lens for $220 or less for Nikon D40?
So far I've found a couple different Sigma's that auto-focus with the D40. One that I'm interested in is the APO 70-300mm F4-5.6 DG MACRO. It's within my budget but the minimum focusing distance is kinda out there at 37" @ 70mm and 51" @ 300mm.
Can anyone recommend something better within my budget that has a closer focusing distance and AF compatible with the D40. I'm not too concerned about focal distance, just 55mm or longer.

Forget about extension tubes. You said that you want to preserve auto-focus and these will not do that for you. Even the more expensive Nikon extension tubes that preserve meter coupling do NOT support autofocus.
You will soon learn than manual focus is better for macro anyhow...
Get a set of +1, +2 and +4 diopter close up lenses. You can add them together to make a full range from +1 to +7, which will get you pretty darn close to your subject. A Nikon set will cost about half what the Sigma lens costs. A Hoya set for your 18-55 lens will cost $56.95 and should be excellent. The same set of generic close up lenses would only cost $20, if you just want to get the idea of what macro is all about without spending much money.
