Hi, I am wondering whether the phase telescope is really needed in my case. I used a cellphone camera to take the picture below (10x zoom). Given that I haven't used phase telescope before and the online images are limited, I don't have a way to compare to make a decision. It is about 70+$ so just w...

Hi Michael, thank you for the link! There are already a few phone-microscopes, but this one seems to be quite interesting. I have a micropeek microscope with brigth field, dark field and fluorescence and bluetooth connection to the phone, but is fairly big and difficult to mount in a detatchable wa...

Thanks for the information. Here is the full set if the phase objectives. They all have PL and PHP markings. Don't know what is the last P in PHP.

Will try your pinhole suggestion..

Hi Bram, thanks for the info. Trying to digest it :) If I understood correctly, if I buy the item in the link below, place it on top of the light source and change camera setting to Grayscale to get the monochrome imaging. Is that correct? https://www.ebay.ca/itm/T00-27mm-Quarter-Wave-Lambda-Plate-R...

Pete, I will try to clean the objectives again. Did it once with water, IPA and ear buds. I got it in a good deal locally. It was 225 CAnadian and the system was relatively clean (except the 40x annulus has a light leakage and one of the eye pieces lens was cracked internally. Otherwise it was in go...

Thank you so much for all the responses Bram. Really appreciate it.

I am kicking myself for selling the zeiss monocular microscope that I had now. Will keep on eye on Facebook.

Can you please let me know where I can get more information about the monochrome lighting?

.. and it doesnt seem to be good for dark field and oblique images.

Here is a sample of phase video I was able to do. Playing with it for few months now. I don't have any prior scope to compare. Not sure whether it is good or need more tweaking. It seems to be centered when I look through the scope.

Are you confident you are employing the phase modality correctly?

Sorry, I was just showing the difference of using the phase objective in normal model. Not sure whether I misunderstood Pete's post.

Thanks for the response Pete. Sorry, forgot to mention earlier that I do have a generic 20 plan acro objective. I compared the image quality of the phase objectives to the acromat plain from Amscope. The normal acromat image and videos are more crisp. The different is noticeable. Please see the comp...

Thanks for the quick response . I am primarily looking at pond life's.

Gurus, I am relatively new to amateur microscopy. Had a microscope for few years taking dust and recently rediscovered the hobby. I have AMScope trinacular microscope (160mm with 4, 10 and 40 acromat objectives) and a fisher scientific phase contrast microscope with 4,10, 40 and 100 place phase obje...
