Re: Focus stacking

This is a non stacked image. If the specimen is situated in a relatively single plane such as the case with thss specimen stereoscopes do very well without stacking. This was a single shot non optimized lighting and my camera is not positioned as to minimize movement. I am not an expert obviously an...

Re: Focus stacking

Actually you can focus stack images quite well with a stereo scope. Assuming you have a good quality stereoscope lighting is the key. There is some compensation required due to the design of steresocopes greenough or CMO. This results in a less than perfect resolution but good enough.These are 2 of ...

Re: Leica PL Fluotar 100x/0.90 Dry

I have used them and find the images to be less than acceptable. As mentioned the highest I go with a dry objective is 60-63X.

PM me your e-mail and I will send you the manual which identifies the objectives it came with. Although there is a plethora of objectives including Nikon, Olympus and Leitz you can use depending on the oculars selected.

Re: Chinese Wild M3 Clone: It's pretty good! [With comparison to mz6]

I agree the Chinese scopes are quite a good value. Given nearly all scopes are made in China, regardless of the brand, it gives the manufacturers access to the same technology. They typically package it into older style stands with various names or even unbranded. I have found they are hesitant or d...

Re: Chinese Wild M3 Clone: It's pretty good! [With comparison to mz6]

I have owned many Chinese clones and have mentioned in the past that at magnifications less than or equal to 40X they are quite comparable to the better known brands such as Nikon, Zeiss etc. It is only at the higher magnifications, if even available, they tend to have poorer optics. But as you ment...

Any 0.5 Aux objective extends the working distance significantly making boom stands more desirable over stands such as the one you are using.

Re: Glycerin jelly permanent mounting

I have had some glycerin jelly I made sitting in my lab frig for years now. Very little discoloration. Although I may see some slight signs of microbial growth. LOL

Never got around to using it. I was trying a different preservative which has worked incredibly.

Re: Nikon Fluor objectives on a Leitz stand

So I have looked at the Nikon 20X/0.75 Fluor vs the Leitz Pl Fluotar 25X/0.60 objective. The Nikon has about a 25% larger FOV which corresponds well to the lower magnification. Resolution of the Nikon objective was slightly better than the Leitz although very close. I stared at multiple Diatoms for ...

Re: Nikon Fluor objectives on a Leitz stand

I have used Olympus splan objectives and they do work. However they also tend to be higher priced than the Nikons. I am always looking for the best value for my money. Although if a good Splan objective pops up I will look at it, especially given the Splans have a wider FOV.

Re: Nikon Fluor objectives on a Leitz stand

If higher n.a. could bring you to use oil immersion the Leitz NPL Fluotar 50:1 1,0 is very good. Originally intended for use without cover slip the 0,29mm working distance allow to use it with one as long as the preparation is thin. Also interesting is the Zeiss Jena 40:1 0,95 dry Apo in the later ...

Re: Nikon Fluor objectives on a Leitz stand

I knew there was some degree of color correction less then Zeiss. Although I have no idea nor read of any way of quantifying it. Hopefully, not sufficient to negate any resolution improvements from the Nikon objectives.
