Check us out at www.tutorvista.com A microscope is an instrument to see objects too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope Types of microscopes “Microscopes” can be separated into optical theory microscopes (Light microscope), electron microscopes (eg, TEM), and scanning probe microscopes (SPM). Optical microscopes function through the optical theory of lenses in order to magnify the image generated by the passage of a wave through the sample, or reflected by the sample. The waves used are electromagnetic (in optical microscopes) or electron beams (in electron microscopes). Types are the compound light, stereo, and the electronic microscope Optical microscopes, using visible wavelengths of light, are the simplest and most used. Optical microscopes have refractive glass and occasionally of plastic or quartz, to focus light into the eye or another light detector. Mirror-based optical microscopes operate in the same manner. Typical magnification of a light microscope, assuming visible range light, is up to 1500x with a theoretical resolution limit of around 0.2 micrometres or 200 nanometers. Specialized techniques (eg, scanning confocal microscopy, Vertico SMI) may exceed this magnification but the resolution is diffraction limited. The use of shorter wavelengths of light, such as the ultraviolet, is one way to improve the spatial …

Present for 8yr old.,
Bought this for my 8 yr old son for Christmas. This is perfect for a curious child that asks a lot of questions about science. Mom and dad having fun with it also.

|Microscope for home school,
We’re Home schooling some boys grade equivalents 6-8. They can be rough on things so I didn’t want a plastic toy and I wanted plenty of magnification to see what we can see. This microscope did not disappoint me. Knowing that many if not all of the lesser microscopes offered have plastic “lenses” this ‘scope’s “optical glass lenses” appealed to me. Images are sharp and clear. Light is provided by either batteries (3ea/AAA) or a wall outlet and there is a well placed easily manipulated switch on the base. You can drag this thing along on a field trip if you wanted to though I can’t imagine why you would. The frame/body is all metal as advertised. The bottom cover is plastic but that’s of no consequence. This unit is made in China and I don’t buy the $450 value claim one bit. But it’s well worth the $90+ shipping which can be avoided if you want to use an Amazon offer. But I bought the scope and an Amscope 50 pc prepared slide box and altogether my shipping was only $4something. I don’t know what yours would be.
The scope came with a transformer and 2 WF view finders though I have not yet figured out how to install the second. It is different from the one that came installed. One person reported their scope came badly packed. Not mine. The instrument came in a thick, fitted Styrofoam box, inside of a cardboard box that was packed in yet another box along with the additional prepared slides I’d purchased in a padded container with the extra spaces filled with large bubble packs. It arrived in fine condition and everything tight.
Harking back to not knowing how to install that second view finder, the “instructions” (I can hardly call them that) are something less than useless as another reviewer reported. That is why I only gave 4 stars to this. Consider the instrument itself 5/star. But, if I used a microscope in school, and I most likely did, it was so long ago I cannot recall it. Therefor the lack of instructions are a bit aggravating. I decided against forking out the money for a book about it figuring (rightly it turns out) there’s plenty of free information available on the web. But, purchasers of this scope should be prepared to do one or the other.
A final word. In doing the web research, I discovered that magnification for the 1000x might want immersion oil but to beware that it is not for all lenses and there’s nought to tell you yea or nay on this scope. There’s a toll free number on the paperwork so I called it. I am happy to report there were no recordings and a gen-u-ine live hu-man being actually answered the phone.(8^o I quickly got my answer, it’s fine to use the oil if necessary. So +1 for customer service.
That wraps this up. I tried to make it useful rather than just glib praise or complaint. I hope it’s of use to someone out there.

|Great fodder for the imagination!,
This is hands down one of the best purchases I have made in a long time (right on Santa)! I have five children between the ages of 1 and 10 and they ALL enjoy seeing things under the microscope, from onion cells, to bucchal cells, to irridescent insect wings. I can’t wait until the weather gets warmer and they can go outside and find new and more exciting things to look at. Very high quality. I would recommend that if you are considering a microscope for kids to use, that you get some prepared slides to go with it. AmScope makes these too, and I am so glad that I got some of those too. Ah, to see the world in a grain of sand…
