I receive many questions on which microscope one should buy. I recommend the following models for amateur microscopy (Affiliate Links to Amazon):
Children’s/Introductory - Swift or National Optical SS110: amzn.to/2WdS4PX
For Amateurs - Swift SW380T (with phototube) or Swift SW380B: amzn.to/3fu7aIY

LEDs can vary widely in color rendition index. One nice thing about halogen is that you're getting the most accurate colors.
Thanks for the in-depth info bought myself a AmScope t-490a custom and I’m loving the quality and sharpness of the image. Thanks again for the helpful advice. Happy microbe hunting.
If you use LED illumination, the CRI if your LEDs is extremely important. Older low-CRI LEDs make any specimen look like crap
I just bought the microscope you showed, thank you very much for your recommendation :)
As always - excellent
Great video. I find that with Kohler illumination, I see practically no difference in the position of the iris as long as it is opened wider than the field of view. However, overall, it helps you keep the light source centered and defocused. It is also necessary if you want to add Phase Contrast system. You must have the light source as well centered as possible, I like the LED over the Halogen, simply because it is brighter, allowing you to take photographs at minimum ISO speed. This is extremely important because the noise graininess increases very fast even at ISO 400. This is especially important with still pictures. Videos tend to somewhat cancel out some graininess because the grain speckles are different from frame to frame.
Thank you for this video, can you tell about the blue filter and the other filters?
Focus lock is the most useful thing a microscope can have in my opinion
As a kid, my first microscope was 50x-900x. I could never focus properly above 450x. Always go for quality, not magnification.
how much harder it is on the matter of focus if I mix different objectives?
Oliver, in January 2018 I found ur channel... and I first watched ur video on "how to choose a microscope" ....then I decided to buy at that instant... to buy a school level introductory microscope...
I have almost completed 2 and half years with it...and have gained a lot of experience from my mistakes...
Do u think.. after this much time. Should I advance in my hobby by buying a new microscope like ur Olympus...
And if yes...than should I buy it like ur old model Olympus ...or the new ones available in market.. like Olympus Cx33 or Cx43...
Please help.. God bless u.
Please how do microscopes limit cell size
Is national geographic 640x good? Are those optical lenes glass or plastic?
Thank you.
Hi Oliver please give me answer can you suggest me a microscope for student. To observe nature
what do you think of the microscope IMAX 40X-2000 LABORATORIUM TRINOCULAIRE, there is one for sale on amazon for 264.84 euros with a camera 1.3mp
then there is another microscope for 550.00 euros but needs a new oil lenz, what does a oil lenz cost,
I want to buy a student binocular microscope bit there is something that is tricking me is actually that i it has to 40× to 2000× so i says there that i can have to 40× to 1000× so can you tell me which one is more better 1000× or 2000× and thank you sir in advance
Sorry for posting similar comments under your videos, but I have just seen several of your videos where you give buying advice for microscopes. I wonder why the difference between brightfield and darkfield microscopes doesn‘t have any part in this, not even in this video, where you list lots and lots of differences between microscopes without mentioning this.
Isn‘t this something to talk about? There are a lot of microscopes out there that only offer brightfield microscopy, while I‘d guess that a lot of beginners (like myself) are searching for the easier to use and much more versatile microscopes that can do darkfield.
i have recently seem some stereo microscopes with a single eyepiece. It makes some big difference?
The whole point of stereo microscopy is to get a 3D view. If it only has a single eyepiece, then it looks like a strong magnifying glass. You can of course do amateur microscopy with that as well, and it will have its uses (otherwise they won't have manufactured it) but if you have ever looked through a "real" stereo microscope in comparison, then you will not want to switch back.
what is a "coula" microscope? Are you saying coola? or cooler? sorry these terms are new to me and I'm trying to help my very bright 5 year old Grandson with a microscope he got for Christmas. ( he wants to look at bacteria)
He is saying kohler illumination - found on better microscopes, not so much on cheaper scopes.
What is an Abbe condenser
It focuses the light from the lamp on the objective. It contains a diaphragm that is used to control depth of field and contrast. Condensers are important for improving image quality. They also have a filter holder.
Which microscope is best for microscopie monocular or binocular
Binocular for two reasons: A. It is easier to observe over long time by looking through with both eyes and B. many binocular microscopes (these days) are of better quality (monocular are often children microscopes, but not all). Do not confuse binocular microscopes with stereo microscopes! Compound microscopes can be monocular and binocular (1 or 2 eyepieces). Stereo microscopes are always 2 eyepeices. They are for looking at different things.
@@MicrobehunterMicroscopyThnaks sir
Ya i have to buy 2 microscope...4x 10x 40x.....10x 40x 100x😂
but nowadays 160 mm standard are not easily available
In the low-cost microscopes they are still common. For high end microscopes (Olympus, Nikon, Zeiss, Leica) the standard is gone long ago...
BEWARE OF UV FROM LEDS
Would be interesting to see how much UV is left when the light leaves the eyepiece after passing through all the glass in the lenses
