DISCLAIMER: There’s no footage of the mod in this video because it’s a 2D video! This is a REAL 3D vision mod. It would require a 3D video to demonstrate! Okay folks. Here's the mod I promised all those years ago (feels like it anyway)! This one is seriously seriously cool and I don't think it's well known at all! Despite all the fancy and expensive gear I've got, this has to rank in my top three favorite techniques. I believe I'm the first person to describe the alteration for folding type heads, but who knows. If anybody has heard of this before or finds some other description of it, let me know! If you have a binocular scope and you're subscribed to this channel, consider this an official Diet Tom's homework assignment! There are plenty of ways to cut corners and optimize this procedure once you get the hang of working with polarization film. Feel free to go off script and experiment! See the description for a PDF guide and a link to a reddit thread for troubleshooting. I hope you enjoy :)
This looks amazing. One thing I love about stereo microscopes is the depth perception. So having that on a compound microscope sounds like a dream. Thanks a lot for sharing. Quick question though: would this work with higher mag objectives or is it solely for 10x ones?
It´s amazing to see what can be done with a simple microscope. I have an OMAX and it seems as everything I need is to apply this technique to jump into a new world of detail. Thank you for this hidden knowledge, apparently there are still lots of microscopists who haven´t heard of this. Thanks!!!
This is awesome. You may have just resurrected an old binocular I have that was collecting dust. It'll be great for this as a permanent~ish setup for that scope.
First of all, thanks for the video, it's a very interesting technique! Just an idea for (maybe) a future video: adapting objectives and condensers for DIY Hoffman Modulation Contrast (HMC). I reckon the process of making the objective inserts would be very much alike for the most part. It would be awesome to let people experience this lesser known and simple DIC-like technique at home
@@AAWOLFE-zc6ly No promises! I haven’t done it before and it looks like it might be tricky to come up with a general procedure. I’d only want to make a video on it if everyone can do pretty much the same thing! Maybe one of you can try it out yourselves and let me know what you learn?
@@microbe_guru I'm planning on using cut neutral density filters mounted on a small circular coverslip to insert in a 40x objective. I will report back in a while. Hopefully the neutral density filters will allow some colour vision
If this works, it is a major thing for amateur microscopists. That would be really awesome. However it could be just like 3d movies: you find it awesome or it'll give you a major headache. 😊
Haha, well it shouldn’t give you a headache! As long as your scope is configured correctly such that it isn’t straining your eyes, then adding this mod should be just as natural! I’ve spent many hours over the past few weeks staring into many scopes with this modification applied.
Hey Carl, good to see you in the comments! Yeah the NA takes a hit although it’s not so bad because you’re mainly only diminishing resolution in one direction. I’ve found it to be quite usable and enjoyable with .25 and .30 objectives although I must admit the .40 SPlanApo 10x looks pretty darn incredible. It’s a lot more difficult to place the filters on that one, though!
Technically you can do something similar with a mono head if you project the image from the objective on a wall and make yourself some glasses with the polarizers oriented like the eyepiece filters. The wall has to be non-polarizing and you might have to be in a very dark room if your scope doesn't have a pretty strong lamp.
Haha awesome! The book is mainly a collection of research papers and related documents - I think it’d mostly only be interesting for a serious Shinya enthusiast. He has another book called “Video Microscopy” which can be picked up for very cheap. About 75% of it is completely outdated info on practical analog video microscopy techniques but it’s bookended with some good general info on microscopy.
I dont really understand no polarizing filter is going under the speicmen how does this not just make everything dark with nothing passing through the polarized lense, I understand the stereoscopy part but not the use of polarizing lense
If you put one polarizing element between you and something bright and unpolarized, it cuts about 50% of the light out and the passed light is polarized in the orientation of the polarizer. They this is set up, the second polarizer at the eyepiece blocks out the light from one half of the rear of the objective and passes the light from the other half. You might check out my polarization peculiarities video for more insights, but the best thing is probably to get some polarizing film for yourself and mess around with it.
So the beauty of this technique is that it doesn’t change anything until after the specimen is illuminated and the light passes through the objective lens. Imagine that you were holding a magnifying glass directly in front of you looking at some 3D object. If you move your head a little to the right and a little to the left, you’ll notice a slight perspective change. What this mod does is the same thing but delivers the left and right views to the eyepieces. Then your brain interprets that as a single stereographic view.
How about instead of putting the two half circle polarizers near the objective's back focal plane, put them into the condenser's filter slot? It should be optically equivalent and one wouldn't have to mod each objective separately.
It’s a good theoretical idea but this doesn’t work well because, generally speaking, polarization is not maintained by your subjects. Especially in dark field where the light is entirely scattered and refracted.

Great video! Thanks!
Thank
I just made the hack. It works like a charm. Thank you very much! It is incredible to know that you can get a stereomicroscope for a few bucks.
This. Is. Amazing. Thank you for such a thorough walk-through. Works perfectly!!
That is a really neat trick!
thanls for the explanations
Fantastic

Interesting - I shall add it to the list!

I tried doing it with Polarising film, but never succeeded. Perhaps someone smarter than me can pull it off.
@@microbe_guru I'm planning on using cut neutral density filters mounted on a small circular coverslip to insert in a 40x objective. I will report back in a while. Hopefully the neutral density filters will allow some colour vision
Wow this is going to the top of my to do list. Thank you very very much.
Amazing video! It's a damn shame you don't have more subscribers yet. I'm sure they're going to come flooding in soon enough, though!

Very interesting! Just be aware that geometrically splitting the objective will reduce the NA.

Love your work , the books look great also.Liking your channel 👍
That's brilliant! Now I wish I had a binocular head.
Technically you can do something similar with a mono head if you project the image from the objective on a wall and make yourself some glasses with the polarizers oriented like the eyepiece filters. The wall has to be non-polarizing and you might have to be in a very dark room if your scope doesn't have a pretty strong lamp.
Finally one that I can make from trash.
OK over a year but I have finally done this and yes worth the effort. Does his book have much of interest in it.
Haha awesome! The book is mainly a collection of research papers and related documents - I think it’d mostly only be interesting for a serious Shinya enthusiast.

Thank you@@diettoms
It may be easier to use only semicircular masking plates for eyepieces.
Rays obscured by one eye are visible to the other eye, and vice versa.
I've tried both and this technique is far more practical and comfortable to use :)
@@diettoms Thank You the answer. I will try both.
@@DrGyarmatiCsaba So, Dr, any update on that?
@@alexandrevaliquette3883 Unfortunately, I have been busy with other things. But I tried it now. The result is devastating. Of course. 🙂
It's really awesome.
How was the sample video made? Where was the camera?

Amazing. Is it doing oblique illumination but at opposite directions for each eyepiece?
So the beauty of this technique is that it doesn’t change anything until after the specimen is illuminated and the light passes through the objective lens.

@@diettoms I will definitely set up one of my microscopes like this when I have time.
@@DP-qb1zw Great! Would love to hear how it goes
