Dark field always strikes me because of the beautiful colors. Thanks for sharing!

You're the Alton Brown of microscopy. Well done, thank you. More, please.

After watching this and doing a little more searching for ideas, I 3d printed a range of sized discs to fit in to my filter holder, which is at the same place you placed your blackout sheet you made, works good to about 0.65 Objectives (4x 10x 40x). One thing I noticed on my microscope was I had to raise the condenser to sit a few MM under the slide to get the dark-field to work. Big thanks for sharing this info as you saved me £80-£100. ; )

Thank you very much Dan! I was considering a dark field, but the price was too high, so having this ability to make a lightfield into a darkfield is much appreciated.

Gave a thumbs up just for the 'something somthing' bit of the vid lol. Thank you for the advice, I'm going to try dark field now!

Thanks! Suggest simplifying by cutting the opaque spots out of black construction paper, instead of using a Sharpie marker and stacking. You can just put a dab of adhesive on the construction paper dot to attach it to the clear plastic.

Thank you! If you will pardon the pun, I found your presentation "illuminating". I just got the wrong type of microscope for what I'd like to do and you gave me so much inspiration. I'll follow and subscribe so my thanks becomes a tangible thing. Carry on!

just ordered a microscope today and I was looking for ways to view darkfield on it ( quite cheap, no commercial adapter available) and with your amazing solution, it's brilliant! thanks man!

I have this strong urge to come down and help you maintain precision! Thoroughly enjoyed the content, great work, and I got to learn something!

Very good idea! Thank you so much for sharing this with us ! I am going to make my light compound microscope dark field now :D

Thank you very much for the video tutorial. I was just needing that for my microscope. You're great!

Well I'll tell ya that was just about the most useful vid I've seen on youtube in a long while, super job on that, I'll be scoping out plastic sheets pronto! Thx

We need more people like you on KZfaq, thanks! :)

Thanks, easy and simple. Keep the good work

Excellent tutorial and explanation, Bravo!

Hi, thanks for the video. I found it very informative and helpful to get more use from my microscope.

very nice, as an amateur I appreciate your video, keep up the good work!

Thanks for this useful Video. It confirmed by suspicion that darkfield is a very simple modification.

Excellent work Dan!

Thank you very much! I'm looking for buying new one darkfield condenser but now I am trying to create it.

thats just awesome. thank you for this tutorial :-) are you going to make some more videos ? you are good at it

Thank you; this I will try. I accidentally partially blocked light from the condenser with a small ruler and ended up with a partial dark field. It helped with the contrast.

Very very useful! Well done!! Thank you very much :)

thanks, i enjoyed your video, it was informative and concise

Excelent and funny video. I just buy a microscope and I am eager to convert it in a dark field microscope. I will try these great idea. Thank you.

Thanks for the tip!! When will you be producing another video?

I really enjoyed this.

Awesome. Best tutorial ever!

I love your midnight movie voice! LoL!!

great tutorial, thank you so much!!

Works well after some time spent with fitting. I made one a couple years ago. How about polarizing for the DIY person?

Fantastic, thank you!

Thanks! It worked very well!

Thanks Dan!!

Oh, thank you very much for that cool idea =)

Very clever... Now please show us how to update it into a phase contrast xD

Excellent ! Thank you so much :)

great work .

I make em from plastic bottle caps. Very rigid, no cost and easy to work with

Thanks!! I was researching here, it's not that expensive slide sheets to print on a laser printer (fortunatly I already have such a printer). I'll try printing some!

here this one can be done also easyand cheap, just 2 polarising filters , 1 for the lightsource and 1 for the Eyepiece (CPL Filters can be found from 3$ each in the analog cameras section on ebay for example on ebay in your country or on ebay china)

You are a good speaker

"Something something something dark field..." Just waking up, thank you for the first laugh of the day! Better than a cup of coffee.

Terrific, thanks!

Much appreciated top job. Thankyou.

Niceeee! This is a killer microscope 'hack'. Thanks!

Great vid! Good presentation, simple, inexpensive, effective! Tnx!!! rc

olique illumination is better than dark field. Simply use LEDs putting them a bit aside on filterholder

Nice video bro.

Genius! I’ll use it thx

Great, for the beginner to understand the case - super!!! What about polarization and DIC? I just bought a microscope and all that extra stuff is so expensive and i have no idea how to apply it :-) i am gratefull for help.

Sir you are a wizard

Thanks

The field can be darkened further by enlarging the shaded diameter. Can we use a similar technique for solar filters on telescopes?

Nice information, do you have any trick for inverted microscope to turn them in phase contrast such easier way?

Thanks sir!

thank u ...so help ful msg ...keep it up ..

Excellent

soooooo good thank you 🙏

Nice video ! Nice person.

Thankyou

My thumbs up came at the something something something part😂😂😂

Hi Dan! What kind of microscope would you recommend a beginner that wants to view red blood cells under darkfield? Thanks for this DIY!

Thank you so much for your vid. Please give me some advice, I am growing some lactobacillus cultures (now trying to replicate some L. Reuteri). I would like to be able to see the action and make videoclips and pictures. Would an Omax 40-2500x work, is that enough amplification??? Good luck!!

omg we need this :D

This might be a silly question but could you do something like this with a flashlight and jewlers loup. By covering the light from the flashlight with the black plastic and looking thru the loup? I know nothing about microscopes! I still have a lot of learning to do. I've been looking at gems as a hobby. I stare at them for hours with different magnification loups and a flashlight. I keep hearing about "dark field illumination" when I watch gem identification videos on KZfaq. Until I can get my own microscope I thought maybe this might be a very rough diy way! Thanks for the video... now when I do get a microscope I'll know how make my own dark field :) Plus it was funny! Nicely done!

How do I know when I have the right diameter for the light block? Thx.

Nice, i need help or direction. I want to see water clusters. Is thier a way.

I tried this method to look at the spirochetes in my blood, and it worked well at 10x. But when I try it at 100x with immersion oil it doesn't work. The image shows up faded and looking like a poor lit version of a light field microscope. Do have any ideas why this would be, and how I can make this work for high power with immersion oil?

Great idea, thanks for sharing. Wouldn’t it be quicker and easier to glue something opaque onto a single plastic sheet instead of colouring several sheets? Or am I missing something?

I wonder if you could just paint the coin you use black and glue it to the transparent material.

How do you film the microscope? do you have a usb lens or you put the camera in front of the eyepiece?

I love you.

Thanks. That´s only works in 5x and 10x. Someone know how to make that in 40x or 100x? I discovery a very easy way to do that , with 5x and 10x, with a specific kind of filter suporter: open the diaphragm and move the filter suporter to the right until you get the image. Will work too.

What would be a good low cost scope for viewing live blood?

can't you just colour a paper circle in black and cover it in plastic circles

Meet Dan, He is a BAMF!!

I gotta look at some mites from the dog

THANK YOU!!! I FINALLY FOUND SOMETHING ON MAKING A DARK FIELD FILTER!!! **Explodes.**

Asewome!!!

So it’s not true or true because of strength that only Arizona & Nevada allow dark field microscopes

❤❤❤ ⚘️🌷⚘️. .Thank You Verry Much..🙏🙏😊😊😊👍👍👍

Brightfield

That guy used is Brain 🧠= 110% 😅

Somthing Somthing Somthing...not cheap...Ha!!! You can say that about so many things today...

I think 7 don´t like this Idea becauce they are selling Darkfield Microscopes .

What is with your odd enunciations ?

stop waiving your hands in the face of the viewer--it;s offensive

brilliant. you saved me a few hundred dollars. thanks.

Moronic bordering on bonafide lunacy

I am here from the future to tell you to buy Dogecoin.... you'll tank me later

Very very useful! Well done!! Thank you very much :)
