okay, if i have a non compensating tube lens does this mean that i shouldnt get objectives from zeiss? i was reading up on it and i read that zeiss typically have lenses that help with infinity correction in the tube

I have an infinity corrected scope, how would i know if i have a non compensating tube lens?

It depends on the era. Nikon was ahead of the curve--in the labophot era they introduced the "CF" series objectives, with all corrections done internally, requiring no eyepiece corrections. This carried over to their infinity-corrected CFI series. If you have an older one it will need eyepiece corr...

wow! this was so helpful, thank you, i recently purchased a nikon 20x planapo objective. i have standard 10x WF eyepieces, would i need different eyepieces? your last paragraph made it seem like the standards that i have will work fine

hey, ive recently purchased a nikon planapo 20x objective, are there special eyepieces i should buy with it? thanks

Does this mean the objective has a prism or polarizer in it so you would only need 1 for DIC? 3. If no to qu...

hey, ive been scrounging around ebay for decent apochromatic objectives and i see that alot of them are listed as planapo or apo. whats the difference between these two? Does the planapo have sufficiently better resolution or is it trivial?

hey, im wondering if anyone knows a good NA for a 40x plan apochromatic objective? which NA is sufficient for a crystal clear image and what NA is the minimum for good resolution. Thanks!

hey, is anyone familiar with the brand LOMO? they are russian, is this a good brand? using Zeiss as comparison would be useful. Thanks

hey, i have an infinity corrected scope and im looking to purchase upgraded objectives. I stumbled across this one on ebay: https://www.ebay.com/itm/Lens-PLAN-APO-40-0-65-Planapochromat-LOMO-for-microscope/333538068363?_trkparms=aid%3D555021%26algo%3DPL.SIMRVI%26ao%3D1%26asc%3D225086%26meid%3D253fbf...
