,,, why is it that when you see photos of microscope & capture set ups of microscopists who clearly know what they're doing..., they are always using DSLRs?... What puzzles me a little is that they are still using cameras with mirrors. After all that effort to provide optical viewfinders, I have my...

So far, I have been quite pleased with the nearly unused Olympus E-PL7 I picked up, to mount on a Wild Heerbrugg, one-inch-sensor, C-mount port, with no intermediate optics. I think the aspect ratio and cropping of its µ4/3 sensor is a better match than I would get with the wider APS-C sensors. The ...

I would want to know at what depth a third party, reticule eyepiece expects the intermediate image, and if that matches the microscope. If the image is deeper into the eyepiece tube than the eyepiece expects (a curse for Wild zombies), you can have a focused reticule or a parfocal microscope, but no...

I decided to purchase a used Nikon Labophot with a phase contrast condenser and objectives from PeteM.... My kids can't wait to get started using it. I bet your kids will have a lot of fun. My parents, both scientists, gave me a brass, compound, student microscope when I was 7 or 8. I think my wors...

That looks like a very fine microscope. Has it been to Antarctica? I think you should advertise that if it has.

A stereo microscope on a boom stand is ideal for electronics inspection. 3-20X magnification is a good range: 3X for quickly scanning a large area and 20X for investigating things that look suspicious, for example, funny looking (is that a crack?) solder joints. Typically people add on an 0.5X auxil...

Yes, I now expect further signs before I entertain the idea that it is more than a typo.

Watching my hyperactive seller maximizing his profit got pretty amusing. I had hopes he could spin his listing into a fourth week, to see what else he would try.

As in a Peltier cooler?

I might try a larger, very low noise and slow turning fan. You don't need a great deal of air flow to markedly increase a heat sink's efficiency.

They seem to be impatient sellers and have already dropped the price to $295 + shipping. I tried to buy a microscope last year, but gave up as the seller kept changing their mind. They kept changing the buy it now price, the starting price and if it should be on auction (the seller let none of three...

I am sure your help was appreciated! Besides, the misdirection was probably partly my fault. I may have been getting too familiar with Michael's problem and should have answered with a touch of proper aloofness.

I will take your word for it. I can see the Images Plus links under Members . If I click on one of them, the site asks me to login. After I do, it updates the page, hides the links and replaces them with: Members There is no software update compatible to your registered product, please proceed to th...

It appears you first need to register the camera to download the current Mac or Windows software, but then updates are free, whatever that means.

... As far as I know there are stereo microscopes today with an n.a. up to 0,65 - but for the price of them you could buy a new car or two.... Yes, I have been thinking of simple and realistically affordable, achromatic stereo microscopes. I should have written that and emphasized it is a matter of...

Perhaps a helpful tidbit. In photographic units, the largest effective aperture of the Wild CMO microscopes I muck with, is around f7.

... I know to avoid twin objective Greenough design, as apparently his is not ideal for photography, and the CMO design which uses a single objective is better suited to the job.... As Bob wrote, all stereo microscopes are less suitable for photography: their twin optical paths would make the micro...

A possible advantage to consider, and it may be of no significance, is that with a zoom microscope, you could make the subject fill more of the camera's pixels. This may prove noticeable if the camera has less resolution than the objective. The decent stereo microscopes that are available to you, ho...

The head of a microscope sales and service company warned me that the weight of the camera on an eyepiece tube was not good for it. I have no idea how much truth is in that. I eventually snarfed a 1970s-era photo tube off ebay, to make the microscope trinocular, along with a mating 1X (optics-free) ...

Good job modding the camera to run off the mains. I have been buying the dummy batteries and then wiring them up to compact, desktop switching power supplies. Here is an adapter I found by searching AlixExpress for "Canon 4000D dummy battery". Three months ago, I bought the variant for an Olympus Pe...

The E200 brochure shows the pieces that can go into the phototube to attach a camera:


They provide the C-mount. This page has component drawings. I better stop there as I am not a Nikon guy.

If the it ends with a c-mount, the photo tube already has a lens that should project a real image, 17.526 mm above the flange. The crux is then: what is the diameter of that image and does it need correction? You will need a relay lens between the c-mount and a DSLR camera, to enlarge the image and ...

I think I may pick up a Celestron NexYZ camera adapter the next time I am in the U.S. I have an AO series 40, student microscope to use it on, once I regrease the focus rack and pinion. The microscope has fixed, high eyepoint eyepieces, is quite sturdy and should have no problem supporting a cell ph...

our colleagues from Bonn have written an honest review of a smartphone adapter: http://www.mikroskopie-bonn.de/biblioth ... k/274.html

It is quite expensive....

Is this the one? I would not grumble if all my photo adapters cost that much.

Is the microscope parfocal?

Have you seen this page, with the words "eyepieces are quite forgiving", thats links to another with the title: "If it looks Good, it is Good"? I pass on the positive waves.

... I guess the moral of the story is that not all Chinese made budget to mid-price microscopes are necessarily of poor quality, and can be a good starting point for someone starting out in microscopy, with them likely to encourage, as opposed to discourage.... The big lesson I draw from the story ...

That is a shame. The door on my Olympus E-PL7 pulls out and pops back in, as it does for this guy.

... (You can always make a slot in the battery cover for the cable to exit) as long as you don't mind invalidating the warranty. How hard is it to change the battery cover, and later restore the unmodified original when you need to? Olympus only wanted 4,90 euros for a replacement cover for my came...

Edit: Removed post as I thought you were a beginner (it is in beginners section), but I see by reading your signature that you already have a 18mp camera, so my post was irrelevant. And I was going to suggest how you might power a camera off 230V, but I can no longer find the post. It is a current ...

Not sure what I made up my mind about? Just researching and presenting the facts to the best of my ability. Oh, there is nothing wrong with that. But when you do, I hope you collect and present the facts in pursuit of what is good and true. In that regard, I am not sure just how far you will get, c...

I suspect that the software that comes with the cameras is escalating the price?... Yes, that "overhead" per camera, if you want to call it that, is much higher because similar development costs have to be spread over much fewer units. On the other hand, if you buy Leica's camera for one of their m...
