Hey guys,
While I recommend that people watch the new version of this video and not the old one, there's one good reason why you should check out the old version also:

In the new version, I calibrated the microscope for 10X and 60X objectives.
In the old version, I calibrated for the 10X and 40X objectives.

So if you want some extra practice, I recommend you try and figure out the 40X calculations on your own and then check out the old version of the video.

Thank you all for your very kind comments,
I'm happy most of you have found this tutorial helpful.

Oh my god, thank you so much. You just dragged me out of hell.

got my a level practical tomorrow. the teacher is a shit so you just saved my life sir thank you

why can't we have educators like this in our educational system?amazing!

It was not just informing but also relaxing to watch his video.  I loved how the simple the video was but at the same time teaching all of the essentials without making it seem too complicated. Also, props to the wonderful music at the beginning and end of the video.

This is a question I keep asking for the last two years from my collogues and no one knew how to do it and they were just estimating the calculations. Thank you soooo much, you increased my confidence as a pathologist.

I've spent about 2 ro 3 hours of revision trying to understand how to calibrate using an eyepiece graticule and this video is the one that made me understand, thank you

this changed my life

This is an amazing easy to understand and follow along video. Perfect to calibrate your ocular micrometer for mycology and spore sampling.

i currently have a lab zoology course and i couldn't understand this specific topic. our prof even sent us a yt vid and i was still having a hard time and was totally unsure of my answers. but your video helped me so quickly right now, so thank you so much!!! i'm your new subscriber <3

Excellent explanation, but could you turn up the volume? , i had some problems for listening. greetings from mexico

Excuse me. Can you add subtitle for this video? This video is really nice. But, English is not my fist language. Thank you.

Thank you so much. It will help me for my upcoming practical examinations

thanks for your practical exipiriment with microcope its very informative. can i have how to calibrate further objective lenses like 4x, 40x, and 100x

if only my teacher could explain like this then I probably didn't had to get grades like D in my lab
Thank you so much for this

It’s been soo many years. But thank you.
You saved me❤
