whoa, you really need kohler pal

jokes aside, great pic!

I'm back, just wanted to post the results of the mod! Despite living in a city of 6M I somehow couldn't find any cheap solutions for polarization, so I ended up getting a small, 10 buck sheet of polarizing film from amazon. Since it's only 10x10 cm I'm treating it like it's the holy shroud. I've alr...

Sorry, I posted the wrong link - here is the one to access the polarization video https://www.youtube.com/watch?v=iNNkdHyvhbs - just need to skip the ad.

Brilliant, this covers pretty much all my questions. Thank you very much.

Circular polarising filters, like the cinema spectacle filters, are linear polarising filters with a 'twisting' layer on the front. The cinema spectacles have the linear filter on the eyeball side ... so if you have two filters out of cinema specs and put them eyeball-side facing eyeball-side ( a b...

If you flip a circular polarizer to the proper orientation, it will work fine. You can probably buy two cheap camera polarizers (sandwiched in glass) for around $20 from various Chinese suppliers. There are two things to watch with cheap polarizers (from 3D glasses, cheaper film, and cheap camera p...

Evening, everyone I've been having tons of fun with my 2nd hand microscope. Since my budget is basically 0, part of the fun has been trying to overclock the thing with homemade filters and cheap parts. Now i wanna dip my toes into polarization techniques, but I have a couple of questions: 1. Linear ...

FWIW, I never said that centering the condenser with the 10x would result in perfect alignment of the condenser with the other objectives. It's general advice given to beginners, and it worked for me. I had a 40x short barrel objective that produced a similar image when the iris was wide open, some...

Welcome Victhree! This seems like an obvious question, but does the new condenser have an iris? And if it does, are using it when observing through the 40x? Hi, thank you! Yeah the condenser has an iris ring, but I always sort of assumed that a larger aperture was better, especially with more power...

Hi, don't sell the phone camera short. For the budget they are ideally suited. 40x looks like residue somewhere. Not a lot to loose if it comes apart. Great route to learn about optics. Thanks for the reply Phil! I finally built up the courage to remove the objective, and indeed it was filthy. I'd ...

Welcome, victhree, and congratulations on you new scope. There are plenty of folks here with plenty of knowledge and experience who are willing to help. I can't say much about your 40X but the pointer is probably on an insert inside the eyepiece. Unscrewing the eyepiece carefully should give you ac...

Welp, this is me officially leaving the lurk zone. Good evening, everyone! I recently got into microscopy after stumbling upon Journey to the Microcosmos on youtube while doomscrolling (seen a lot of that on the forum :lol: ). I have no background in any kind of science, but their footage is breatht...
