Where was this video when I was first learning microscopy? It would have cleared up a lot! I've been doing microscopy professionally for over 10 years now, and this still managed to teach me a lot that I didn't properly understand. Thank you, Steve Ross!

These are excellent videos. An accompanying, downloadable slide show would be great to have.

Very very good video and presentation. There is little like this on youtube

Learned much and lots of potential to comprehend even more. Thank you.

Thanks Stephen..Nice job..

Fantastic lecture. Thanks!

Fascinating, thank you.

Was hoping you would give us some general eyepieces and objectives that cover low power, medium and high power.

when using light microscope do you start the largest or smallest distance between the lens and specimen/why?

Fantastic , what is the difference between a DIC L and DIC L/N1 Nikon lens

If a lens was made parabolic would this correct for spherical aberration?

What's the Difference between PL and WHN with respect to eyepieces?

Thank you!

Thank soooooooooo much 🤟 u really helped me get out of query which was haunting me from several days
