Is it some kind of microscope?
Hello everybody,
I would like to ask you whether this "thing" can pass as a microscope in the general sense:
1.) microscope - objective
2.) tube - lens
3.) eye - piece
4.) object - table
5.) cross - table
6.) condenser
7.) fine - drive
8.) filter - holder
9.) photo – tube
Best,
ADi

Sure, though if it doesn't have a viewing eyepiece it's a fancy digital microscope.

Re: Is it some kind of microscope?
Most "microscopes" have substage (transmitted) lighting for viewing slides, so from that perspective this is not one since it can only do incident (reflected) lighting.
edited to add: beautiful system, though it would benefit from an idler rail for stability
further edit: love the Harley clamps. I have been using them recently as well

Re: Is it some kind of microscope?
I would qualify it as a custom arranged microscope: both magnification, resolution and main optics -the objective- are typical of microscopes.
For Nikon Small World Competition people it also is:
so...you're a microscopist or you aren't depending of the context
* and a very nice one!

But for placing the images taken with it at photomacrography.net right forum this is a macro rig* and the images it produces will be placed at our Technical and Studio Photography -- Macro and Close-up forum"The homemade microscope is a new and growing sector of the contest and we are excited to collect and judge these images"

Re: Is it some kind of microscope?
Where did you find this quote? I remember reading something similar in previous years, but when I check the current rules, I can't find anything like it:Pau wrote: For Nikon Small World Competition people it also is:"The homemade microscope is a new and growing sector of the contest and we are excited to collect and judge these images"
https://enter.nikonsmallworld.com/small-world/rules/
This is the most relevant rules:
I still think that it would be perfectly fine to submit images taken with the rig above, though.-Images must be taken by Entrant using a light microscope. Images taken with an electron or any other microscope(s) that do not capture imagery using optical light technology are not eligible.
-Macro photography is not eligible.

Yes, a magnifying glass is used as an eyepiece, namely this one:Sure, though if it doesn't have a viewing eyepiece it's a fancy digital microscope.

Hello Ray_parkhurst,
For this reason I use the the Köhler from Lomo: Best, ADiMost "microscopes" have substage (transmitted) lighting for viewing slides

Hello Pau,
Yes, I would like to know if I may take part in the Nikon competition :-)

Hello Viktor j nilsson,
No particular brand of microscope is required.
Then it seems that this one made by ADi can be accepted :-)

I think so too.I still think that it would be perfectly fine to submit images taken with the rig above, though.

Re: Is it some kind of microscope?
It's basically set up much like a toolmaker's or measuring microscope then, like the Nikon mm-200: one objective, one eyepiece, optionally a camera too. They also make various digital microscopes with no eyepieces of course (just look at the cs-20 or the shuttlepix, whatever that was)Adalbert wrote: ↑Thu Apr 22, 2021 12:08 pmHello Scarodactyl,Yes, a magnifying glass is used as an eyepiece, namely this one:Sure, though if it doesn't have a viewing eyepiece it's a fancy digital microscope.

I would guess their macro/micro division is really more about having a fixed stand and a microscope objective rather than a macro lens on a handheld camera.

That was a personal communication from 2016, reported by Chris S.

I guess the current rules are intended to convey a general concept, while leaving the competition officials some wiggle room to make ad hoc decisions.
It's tempting to think they could just say something like "images must be made using light, with subjects no larger than <specified size>". But then that would rule out some fancy new research scope that manages to capture a huge field at high resolution. Writing formal rules that have just the right effect is hard; leaving some wiggle room is much easier and probably better for viewers of the competition.

That is true for its specific purpose, but not in the "general sense" asked by the OP.Scarodactyl wrote: ↑Thu Apr 22, 2021 11:03 amMetallurgical microscopes are still microscopesray_parkhurst wrote: ↑Thu Apr 22, 2021 8:19 amMost "microscopes" have substage (transmitted) lighting for viewing slides, so from that perspective this is not one since it can only do incident (reflected) lighting.

I think you can safely consider your rig a "home-made microscope" for the Nikon Small World competition.
A few years ago, I contacted Nikon Small World official Eric Clark to ask whether images from our home-made microscopes--which of course we call "macro rigs" here for reasons that work for us--are eligible in the Nikon competition. As an example, I shared posts detailing my macro rig, the Bratcam. He confirmed that for the purposes of Nikon Small World, the Bratcam is a home-made microscope, and images made with it are eligible for entry.
He added: "The homemade microscope is a new and growing sector of the contest and we are excited to collect and judge these images." I took this as an endorsement that images from rigs like yours and mine are not only permitted, but very welcome.
It may also be worth mentioning that before I asked this question, it seemed obvious that a considerable number of Nikon honorees across various years had already been making their images with home-made microscopes. Clearly, images from systems like ours had been accepted whether competition officials realized it or not.
Looking just now at the "Guidelines and Restrictions" for the competition, I don't see any obvious changes from when this communication took place, so would conclude that the answer I received is still in force.
Good luck, Adi!

PS--In another communication, I checked with Eric Clark to make sure that our Administrators Appreciation Awards would not disqualify an image from Nikon Small World entry. He confirmed that our awards do no such thing.
