Be careful using aluminum foil as a darkfield stop; it can reflect heat back into the lamp and cause it to overheat (less of a problem for LED scopes). I've used black cardstock which works well and absorbs a lot more of the light rather than bouncing it back downward

This was probably the coolest part of my aerospace structures lab. We used the same concept to visualize stress concentrations around a hole in a material. The material itself in our case was one of the polarizers but it could be applied to any material that has a noticeable birefrigence optical property.

Not a nematode expert, but by the way that worm moved, I think its a microscopic annelid. All the nematodes I've looked at move by thrashing about, whereas your worm is using peristalisis.

Thanks a lot for this excellent tutorial! I can confirm this works very well, but the polarizing filters need to have NO scratch, else the image will be very blurry! I found that polarizing sheets can often come scratched, whereas polarizing glass filters for cameras are more robust and provide the same result (that's a tip I found on a microscopy forum), so in the end I am using polarizing filters for cameras and this works very well. Also, using 2 circular polarizing filters is better than the typical linear polarizers because with circular filters we can still see some material that would go totally extinct with linear, as described in this paper: Higgins, M. D. (2010). Imaging birefringent minerals without extinction using circularly polarized light. The Canadian Mineralogist, 48(1), 231-235.

Yes, it's great to see these cheap and easy ways of producing more advanced modes of illumination. I have found that you can get really good darkfield images by leaving your microscope light switched off and just shining a reading light or even a strong torch (flashlight in American) across the axis of the normal brightfield lighting, ie horizontally, parallel to the floor. It's a pity there just doesn't seem to be an easy do-it-yourself way of getting phase contrast lighting, unless you have invented one!

Very good insight of polarized and of dark field microscopy. I'm curious about a couple of things, though. As my degree is in photo science, with a good splattering of basic optical design and engineering: 1. Do you really need to stack the black mask or is that to create opacity for the mask. Why can't a singular, opaque circle of the correct diameter, mounted onto thin plastic be used? 2. Why does the positioning of the upper polarizer need to be so critically placed (on the inside, upper housing v/s the bottom of the eyepiece? Thanks, great work and narration.

If you put a piece of polystyrene (e.g. smashed petri dish lid) between the first polarizer and specimen you will get a retardation plate. This creates some absolutely stunning background effects like colour gradients and such.

@thethoughtemporium6 жыл бұрын
I'd stick to white honestly. You can do rgb but you'll end up with weird effects.
@AltMarc6 жыл бұрын
I understand that the mounting of the RGB could be problematic to obtain a constant color mix…, if it is that what you're referring as "weird effects" ? But you can buy color filters for "white light" microscopes..., That's my reason asking about RGB. Could also add UV and IR leds so that the RasPi could change the colors automatically while taking pictures. Could be a nice Open Source project, but I can understand that if you already have white "LEDs", their is no reason to change… but if you have a Pi cam mounted… Perhaps getting other viewers, while YOU explain to us "How UV fluorescence microscopy works" (and caveats), doesn't have to be a long video.

Joats yes they do, but the glasses are analysing filters which make the circular polarization to an linear. Left and rigth hand polarized ligth produces linear polarized ligth with a 90 ° rotation. A second linear pol filter seperates them per eye. If you shine ligth thru the glasses they get linear polarized, is what i wanted to say XD
