Regarding software compatibility …
This line from the previously posted spec. for the camera is [if it is entirely true] very useful:

Support for drive free protocols: USB Video Class (UVC)

Sorry, I will have to keep this brief for now, and hope that others in different time-zones will fill-in some of the gaps The different frame sizes are available for convenience … depending on how you wish to view or record the imagery, … What is not disclosed, is whether the smaller sizes are simpl...

@MichaelG: I understand some of what you're saying, but what numbers do I multiply to find out the active area vs the physical chip size? If Sensor size: 8.365mm(H)x6.615mm (V), what do I need to look at to compute active area? I'm a bit lost here... But thank you for your feedback! I'm learning a ...

I have no personal experience of the HAYEAR cameras, but that specification is remarkable both for its resolution and frame-rate. … both very impressive. One thing I would mention though is the chip size Do the maths and you will see that the active area is significantly smaller than the physical si...

Thanks for the [overnight for me] burst of activity

Thanks for that Erik … I will sleep better now

Welcome, Alexander MichaelG. Translation to English reads: Hello, my name is Alexander, I'm new to microbiology, but I'm very interested in the B 102 C microscope, two capacitors, light and darkened, but this microscope is not very suitable for me, I came across the choice of Olympus BH2 Flourescent...

I am a little disappointed

An interesting little mechanism … thanks for sharing the photos

I was rather surprised to find this “admission” by Leitz, and would welcome comments from the wise:
… perhaps the original German expresses it a little differently [?]

I’m afraid this won’t help [or make you happy] : https://www.ebay.co.uk/itm/256205241887

Hopefully, in amongst that lot … you might just possibly find a blown fuse !

… if not, it could be a long investigation.

An interesting short paper, which was mentioned on Apple News [Popular Mechanics] : https://www.sciencedirect.com/science/article/abs/pii/S0012825223003094?via%3Dihub Free download if you have ‘Institutional Access’ Sounds to me like Gaia is taking care of herself … but the naive humans don’t unders...

Thanks for heads-up, and the photos. To me, what you have shown with the green LED looks great to me... but disappointing for you. Because of this it is obvious that I don't know much about microscopy, and have lots to learn. . Fear Not !! We all have lot to learn … that’s one of the beauties of th...

My solution to the above post is to drill a hole into the end and insert an optic fibre. Then light proof the whole thing, except for the end of the projected fibre. . I regret to say, you are likely to be disappointed … Fibre Optics have an ‘exit angle’ MichaelG. . Here are some reasonably self-ex...

… I think, still, that the OPs project will still offer some interesting results …

Most definitely … I’m looking forward to seeing them

The subject gets a bit heavy, Gerry … but this is a good introduction:

The visual perception of a particular colour does not necessarily mean that colour’s actual wavelength is present.

… I plan to use aluminium foil to cover the light head; it may make a slightly brighter beam, as well as blocking the light leakage. An impressive start !! In an ideal world, however, you would polish those sawn faces and get total internal reflection [ big trade-off in the realm of reward-for-effo...

It may be worth exploring these: /https://www.adafruit.com/category/168url

Ada deserves a lot of credit for her development work, but I should mention that even-cheaper ‘clones’ are to be found on ebay.

In the immortal words sung by Julie Andrews:

I wish I could be so meticulous and thorough.

Welcome aboard !

That is a magnificent ‘first microscope’ … !!!

Ron Green’s brilliant paper is available here, in several formats: https://archive.org/details/APracticalG ... ollimation

I suggest you skim through it, for an appreciation of the problem, and then return the Amscope.


MichaelG.

Thanks for that ^^^

On a happier note: the ‘scope obviously has great potential
