Help connecting camera to microscope


Recommended Posts

Hello,

 I hoped to manage by myself but after a week and multiple adapter buys I haven’t managed to connect a camera to my microscope. 
First this is my microscope. It is a sumulfocal trinocular. 
Specifically this one 

Vision Scientific VS-3F-IFR07... https://www.amazon.com/dp/B01KOPGCES?ref=ppx_pop_mob_ap_share

 It is currently setup with a 0.5 Barlow lens. 
 

As you can see it has some kind of camera adapter with a focus adjustment  which came with it. But the top is not threaded it is just a metal tube and I expect you are supposed to have a camera which just slides in. 
That drop in tube can be unscrewed as shown in this picture  the inner diameter of the female threaded part is 25.3mm

The whole optics for the camera can also be unscrewed that female threaded part is 27mmimage.thumb.jpg.8107135a9bf657e87927aad6ee1b24f2.jpg

This is the camera I am trying to connect.

I also have the two adapters below:

SZM CTV1/3 and SZM CTV 1/2

as well as so called C mount to CS mount adapters (little 5mm spacers)

My problem is the following:

 can thread either of the SZM adapters into the microscope 27mm screw hole (what is left when I remove the camera optic which came with the microscope) I can also screw the other side of either adapters into the camera with or without the C to CS spacers which fit between the camera and the adapter (not between camera and microscope)

however when I use any of this combinations I cannot have an in focus image from the camera the focusing adjustments from the adapters seem to be just not enough. 
 

On the other hand if I just hold manually the camera above the built in optic I have a beautiful picture but no way to attach it that way. 
 

Does any of you know of a solution. Maybe yet another adapter which would screw into the amers and drop into the tube. Or a replacement for the tube of the same length but threaded to thread into the camera?

I was so looking forward to be able to take nice pictures and video of what I am doing as well as to show on the screen to my family what I am doing but right now I feel stuck.
 

Any advice would be welcome.

I have an Eakins microscope which looks pretty similar to yours. The only thing I needed was a C-mount adapter. I got mine on ebay, it looks like the one below (but is a 0.35X, not 0.5X) That just drops into the trinoc port and is held in place with a grub screw and then the camera screws onto the top part. I also use a 0.5 Barlow.

In addition you will need a c to cs adapter which is just a 5mm ring to bring the camera at the right distance. 
 

The camera I have is a Hayear camera I got from AliExpress. It does the job but I find the usage a bit clunky. But I don’t know if others are better

I had the same issue. C to CS adapter:

Not sure where you're located, but your amazon link looks like a US market one, so that should work for you.

I even got a 4-pack; one for each power, plus one for @gpraceman (did I give that to you already?) to complete his set. I'm not sure having one for each power is worth it, but they were cheap.

@Malocchio@GuyMontag I have a camera which looks awfully like yours and use it plugged in to an HDMI monitor.

Once it works it is fine (not sure about the recordings yet I should be able to access them tonight) but everytime I restart the system there is this weird dance between turning on the camera and the monitor and the monitor not detecting the camera then turning the monitor off and on and the camera the same and so on till it is finely recognized.

Have you experienced that and what is the best way to turn on the system (the 2 sheets of manual are laughable and don't help)

I do have one that I got from AliX.  But thanks for the thought.

Yep. Whenever I plug the usb cable I do it twice. I plug in the cable, pull it immediately off and plug in again and the yellow LED in the camera lights up. Weird but that's how it goes every single time for some reason.

What do you use for a camera @spectre6000?

I use the one @gpraceman suggested... (turns around to look at scope) Hayear. Ali-X special. Good for low power stuff like watchmaking and electronics. Sucks for anything high power that relies on eyepieces for obvious reasons. For that, I got a screw adjusted eyepiece mount for a phone. It's fiddly, but I can get something like 270X, which is pretty substantial for a scope like this.

The photo I posted was just an example to show how the camera connects to the microscope. I used to use a setup similar to that but I now use a mirrorless camera. When I did use that type of setup I didn't connect via USB, I just saved to the micro SD card.

Hello,

another question.  Is there a good way to record audio at the same time as the video without using a separate device which would then require to synchronize both?

I noticed when editing the video that there seems to be an audio track with it but basically empty except what may be noise.
