🔬 Infinity vs 160mm optics

For low-cost microscopes, the 160mm standard is still the most popular one.

Hi! Oliver Kim. Can you please try to make a video on effect of different types of mounting medium on few common specimens. Example:
1. vegetable oil
2. eupral
3.clear nail paint
4. water based glue
5. Alcohol
etc.
Do it when you have time. Good bye!

Very intuitive. Many thanks. I've got a question that puzzles me for some time.
I've seen that some manufacture of the CCD for microscope (not manufacturers of the microscopes but of CCDs) that produces CCDs with miniature motors inside that justifies the sensor. By fixing the microscope stage and the objective lens, they can use the CCD to focus the specimen instead of using the focusing knob. It sounds like that one can use the eyepiece to focus the specimen instead of the stage. How could it be possible, and is there any theory behind it?
Many thanks again !

hey brother very informative video, I am trying to find a microscope for my family one that is trinocular with infinity objectives and 110v ( i am having a very hard time finding one with all these features, especially 110v) to use in a regular 110v system I only have 240v in wash room for dryer but dont want to use microscope in wash room lol, thanks for your help and for all your hard work on this channel, we appreciate you greatly brother! 👋

[My.channel]

thank you ))what about quality example 10x amscope 160 achromat comparing with amscope 10 x infinity achromat ??!

I'm studying biology and I recently totally fell in love with the kingdom of protists.
I've been observing water from ponds around my neighbourhood but I always seem to come across the same types of protists. Is there perhaps any technique that would allow me to observe more variety? (aside from using grass/hay and water in a jar)

[israelramos]

Excellent video as always! Thanks a lot!

I wish camera makers made standard mounts to adapt to any body like microscope threads. Camera manufacturers seem to have polluted the environment by modifying adapters widths yet very little differences in lenses.

Is there a video somewhere that tells us about the markings on a 160mm lens? Mine have the following: red band (is this a standard?) 4/0.10 160/0.17; yellow band 10/0.25 160/0.17; blue band S40/0.65 160/0.17.

Thanks for your video, i would like to know if there is a way to adapt at ube lens on a "finite" microscope in order to mount "infinity" lenses on it? i 've just get a very good Olympus BH microscope with bunch of finite lenses to uses with it, but i'm thinking to a possibility to use my Mitutoyo infinity lenses (that i use on my camera for macro photography) on this Olympus BH microscope, of course i understant it needs a tube lens, but is it possible? thanks

Hi! When you have beam splitters, infinity space is better - quality-wise, because you don't have ghosting.
This is something that seems important to me. Especially when using epi illumination.

[BHFWaterloo]

So my question is do infinity corrected microscopes with plan objectives produce a better quality image than a microscope that is finite without plan objectives or a microscope that is finite with plan objectives but just not infinity corrected.

Hi Oliver, Thank you so much for having this channel and I've learned a lot from you about microscope. Recently, I got a chance to get a zeiss microscope and along with the microscope, it got three objectives, Zeiss EC Plan Neofluar 5X, 10X and 20X. I checked online for a higher magnification objectives with the similar kind and found these objectives are super expensive. Is there a way to use a cheaper objective lens from Zeiss? I noticed EC Plan is the latest version, can I use Plan Neofluar instead? Many thanks for your time and look forward to hear back from you.

[geoffgeoff]

Perhaps something about long distance objectives.

[PeterBrockie]

Interesting video. I now know I went about this all wrong. haha I bought a nice AmScope (~$1k USD) and figured I'd upgrade the objectives over time. I managed to end up with UPlanFL 4x/10x's from Olympus which are infinity corrected and have sexy fluorite elements and an old Zeiss 100x 160mm model. The funny thing is that even using the wrong infinity Olympus lenses produces a better image than the stock 160mm AmScope ones at least for my hobby level silicon IC viewing. :P

I guess I'll keep my eye out for proper 160mm replacements.

[AndonGospov]

I was surprised to find that Russian microscopes are almost always infinity corrected. Even the low cost ones

[lotharmayring]

a infinity system is much better than fixed tubus objectiv. The numerical aperture of infinity is higher if you by quality. Also a good infinity objectiv is normally plan apo or fluo. The price is higher but the image quality is much better and so ou make a real good upgrade. wonder if microbehunter sells this objectives

[DeniskaNYC]

Great videos. Thank you.
I'm new to microscope can you explane diference berween DPan and SPan lenses for olimpus.

[raufulmizan]

hello mr Kim, so the infinity and finity systems is only for optics (objective) ? or the combination of optics and their stage, I mean there are microscope that infinity systems and there are finity ??.

[ElGeologoModerno]

Hi, I own a AmScope T490B-DK microscope with 160mm optics. Recently, I bought an infinity 40x Plan Fluor objective but it doesn't work properly. The image you get is more or less like the one you get with 160mm objectives. Now I know the reason, thanks for your video. Is there any way to work around this problem? I mean, can I force my microscope to take adventage from infinity objectives? Thanks!

[vijaygangurde]

may god bless you again Oliver Kim! Thanks for choosing my question! Keep it up
