American Optical Turrets and parts (no longer available)

Hello everyone, I have a few objective turrets 2 5 position for an AO 110 and a 4 position which I believe came from an AO 10. Free to good home for cost of shipping. Shipping only within the Continental US. I also have some stage slide holders. A complete stage for an AO 110. ALL free for cost of s...

Re: Leica M80 Plan Objective

To be clear I agree the Leica Plan 1x objective is probably well worth the $800 especially given the original suggested pricing. I myself tend to try and get the maximum performance for the minimum dollar ( cheapskate--LOL). I have been looking at Leica Plan Apo objectives wondering if the performan...

Re: Leica M80 Plan Objective

I cannot attest to the performance of the Leica Plan 1x objective #10450167 vs the Wild Plan 1x objective I am currently using. However, I can attest to the superior performance of the Plan 1x Wild objective over the Leica 1x achromat. Given I purchased the Wild objective for less than $200 vs the $...

Re: Higher power eyepieces beyond 10x?

It is recommended on Nikon's website for stereo microscopes when you want to increase magnification without losing DOF increase the eyepiece magnification. Increasing the magnification of the objective reduces the DOF. However, keep in mind that increasing the magnification via the objective vs the ...

Re: Has anyone ever used LWD condenser?

I agree with PeteM. The resolution of my leitz objectives with the phase ring always seem to be slightly less sharp although the na listed on the barrel is identical between the two. Also specimen thickness can result in some additional distortion when using a phase-contrast set-up.

Re: Has anyone ever used LWD condenser?

Most dedicated inverted scopes have an na of 0.55 or less. The LWD objectives commonly used, tend to have a lower na compared to their normal distance counterparts. Thus, the two work well together. Having a condenser of 0.9 na and objectives of 0.65 or less would have no benefit.

Re: Leitz Plan 1.6X objective

A historical search yielded a low of $75 for the 170 TL version and a high of $299 for the 160 TL version. Hmm..I may list it for $250 or best offer. I also have an extra 2.5x as well. I may just list that one and hang on to the 1.6x for a bit longer.

It is quite some special objective requiring the fitting condenser.

I definitely agree with you on the $1750 That is why I asked..LOL. G...

Leitz Plan 1.6X objective

So I have been looking over my collection of objectives. I have a Leitz 160 TL Plan 1.6X objective I was considering selling. I went to e-bay to get an idea of what price to set. Generally, I simply list it for less than the lowest priced unless I consider it below my personal valuation of the objec...

Re: Leica M80 Plan Objective

Within a system it may not vary as much, but typically when you move up to the higher tier of objectives (nikon HR, Leica 65mm series etc) working distances drop and resolutions increase since they need to handle higher max magnifications. The resolution on the 1x plan apo on my M10 knocks my socks...
