Nikon to trinocular port adapter

#1 Post by Phosphomicros » Mon Jul 19, 2021 12:33 am

Hello,

I'm new to microscope use and was hoping someone here can answer my question. I am mostly photographing 3-dimensional micro minerals.

Currently, I have a Hayear camera (https://www.amazon.com/dp/B07WC1PN69/re ... UTF8&psc=1) hooked up to my Trinocular Amscope microscope (https://www.amscope.com/3-5x-180x-trino ... ights.html) and it has pretty poor clarity.

Because of this, I'm looking for a way to connect my Nikon D3400 to my 38 mm trinocular port. I also have a small metal adaptor between 38 and 25 mm if that helps. Do you have any suggestions on how to get crisp images doing this? Would this even help, or should I go another route to get clearer images?

Thank you so much for your time!

Sure, you can hook up the Nikon camera, with adapter Nikon F- 38 or 25mm; see for example
https://www.lmscope.com/en/Nikon_Adapt ... en.html
You can also find the adapters at Rafcamera, or cheaper on Ebay or Aliexpress.

Not sure it will improve substantially the image quality.
Your current Hayear camera is rated 34 Megapixel, well, that's absolutely overkill, don't expect to get pixel-sharp, huge 34MP images. Your Amscope can give max 1 to 4 megapixel images I guess. You need to stay content with that; or invest more $$$ in optics.
Before buying the adapters, try to fiddle with your current camera: spacings, distances, put in or take out the 0.5x lens... maybe you find a combination working better.

Remember also that at high magnification, depth of focus is thin, so a crystal will be in focus only in some area, rest out of focus and blurry. Nothing can fix that, apart focus stacking & elbow grease.

Other routes:

Try to take photos with the phone camera at the eyepiece. Are better than the Hayear? If yes, use the phone...
If it is more or less the same, well, that's what your Amscope can do.

Try to use diffuse illumination. Like, a sheet of paper in front of the lamp. Or a roll around the mineral. Greatly improves the image.

Since you have a Nikon, get a macro lens "Micro Nikkor 55mm" secon hand (make sure it's AI)
The magnification is limited - 1:1, about 5 - 10 micron details. But crisp images, sure. Depends how big are your crystals. Or any other modern 1:1 macro lens.
Macro lenses are goood. 1:1 is already a lot.

Also mounting the Nikon kit zoom lens inverted (get adapter Nikon F - fliter thread + macro ring spacers) gives big magnification, decent crispness on the cheap.
Doing this with the Micro 55mm above, works even better.

Try to stick (with tape...) the Amscope's front attachment lens in front of Nikon's camera lens; it may just work decently as super-macro.

More magnification, done properly, you can hook up a 4x or 10x microscope objective to the Nikon camera. Expect a lot of fiddling on focus and epic fights against vibrations.
For those setups, look in the Photomacrography forum:

A true microscope, only if you are going very very small. And here you will need to abandon 3D effects, because of the very shallow depth of focus.
