IQCrew by AmScope 40X-500X Kids Inverted Compound Microscope for Students

Great for kids! Purchased for my 5 year old. Quickly became a hit with kids in the neighborhood. Comes with everything you need - learning guide with experiment ideas and tips, pre-made slides, batteries, tools to collect specimen, etc. The pre-made slides are fine, but the real fun/learning was the kids finding bugs, making crystals, etc. One product tip: the eyepiece arrived unattached and needs to be “popped-in” place. I was a little confused when I first opened (not a microscope expert!), but once assembled everything was really easy. Great value based on the fun/learning we’ve had already. Seems well built, so assuming we’ll have it for years to come!

The media could not be loaded.  I am an amateur microscopist and have purchased several of these for personal use and for gifts for young people. It is unique because it is the lowest price inverted microscope sold anywhere. It can be used for both slides and samples in petri dishes. I have many expensive, professional inverted microscopes to compare it to. It is very good for the price you pay. I created a Facebook group specifically about maximising the potential of this microscope. It is very tiny and lightweight plus has a self contained battery powered LED illumination, so makes a good portable field microscope. The biggest problem is that the stock eyepieces aren't good, which can be cheaply upgraded, about $10, and it doesn't have an iris diaphragm to control contrast. That can be remedied with either a free, self made, cardboard oblique filter or a $20 add on iris diaphragm. Inverted microscopes are great for beginners and advanced amateurs so that can observe water life in a much more natural environment than on a microscope slide. You can watch the same organisms for a days and have long observing sessions without them drying out, being crushed or dying from lack of oxygen. It is very easy for children to use and can be used for variety of illumination techniques like bright field, oblique, polarising, epi and Rheinberg illumination. All are shown how to do easily and cheaply and demonstrated on the Facebook group about it. I keep one on my boat for fresh plankton observations. They are great travel microscopes, also. I've taken one around the world in a backpack, a motorscooter and airplanes. Check the IQCREW inverted microscope group on Facebook to see all that it can do and for support about using to its fullest potential.

The microscope for the price optically performs excellent. I already have an Omax M8311 so I can compare. Inverted microscopes can explore specimens in the Petri dish and this was the reason for buying it.I didn't like the limited range control of LED brightness - particularly when exploring specimens with low magnification. Despite setting it to minimum, it was still bright for my preference.Being proficient in electronics I made small changes around potentiometer 1k Ohm controlling LED. Now I can control the full range from completely dim to full brightness.The picture tells all. Add a resistor 1k as shown and change cabling between batteries and LED (else you would drain the battery despite the switch is off).I already have 25x eyepieces so I bought the set with just one eyepiece 10x. This limits magnification to 200x but for my purpose (educating grandchildren) is enough.

This will be a fun new perspective in microscopy for me. Inverted microscopes are very expensive both new and used. Although it doesn’t quite provide the quality images equal to my other scopes, it is much better than I expected. It’s very light and someone suggested anchoring it with Velcro so it’s more stable while in use. I may try that.

Purchased this as a gift for a very curious 7 year old. Was told that when he opened the gift, he hugged it and said that he has waited all his life for a microscope. Can only speak to his reaction and not to the quality of the product, but the child’s mother is a scientist and she seemed pleased!
