WTB: Optiphot Bertrand Bino Head

Hello,

I'm looking for a Bertrand head bino for my Optiphot. Must be in working order with no issues.

Regards,

Re: Polylite SC endusers(?)

A few test images with the Polylte SC. I should have added a few more photos to the stack for complete focus. Oh'well. This is a Calcite sliver photographed with my Polylite SC. It's the same stuff Wollaston Birefringent prisms were made out of and used in a Polarimeter to measure magnetic fields vi...

Re: Polylite SC endusers(?)

I should have done a better job centering and rotating the actual image. Oh well. Here's a screen capture with a grid.

Re: Polylite SC endusers(?)

The very first thing I tried with both scopes was a direct project approach. That was at least three years ago. All I really know is it didn't work. I also had some pincushion going on, but I also don't remember what the setup was that caused it. The attached image is from yesterday, taken with the ...

Re: Polylite SC endusers(?)

Just another test. Here's a single-shot image taken with the MET and SC. I used the exact same objective (20x0.40 IK) in each. I removed it from one of the scopes and placed it into the other scope. It's the same wafer but in a different area. The SC has that Telan lens (?) in the top. As you know, ...

Re: Polylite SC endusers(?)

There is a big difference between the image viewed through the binos and captured by the camera setup. The MET came with WPK 10x eyepieces installed in the bino head. The MET and SC are different. The MET doesn't have a lens in the top plate as does the Polylite SC. The MET was set up for a film cam...

Re: Polylite SC endusers(?)

Not that anyone cares. I finally have both the Polyvar MET and Polylite SC configured for a DSLR (APS-C ). Each configuration was a little different for each scope. All parts on the MET were 3D printed. The 3D printed components are not as ridged as matching them would be, but they work. I wish I ha...

A circular polariser consists of a 1/4 λ plate and a linear polariser. If you have one lying around, take it apart and you have your waveplate with an additional linear polariser.
Thanks, all the ones I've ever seen are glued together.

Re: Polylite SC endusers(?)

What should the measurement be from the eyepiece shoulder to the flange on a 50D?

What camera are you using? I don't recall.

If you can set the shoulder of your eyepiece at 7 1/8" ( not the surface of the top lens) ......
I just want to clarify the dimension, from where to where, before I draw up something to 3D print, please.

Any way of trying an approx. 40mm lens to sensor distance?
I don't understand the question? Do you mean sensor plane to eyepiece? The Canon 50D is 44mm from the sensor plane to the flange on the front of the camera.

Re: Polylite SC endusers(?)

If you can set the shoulder of your eyepiece at 7 1/8" ( not the surface of the top lens) you would get parfocalization and then be able to adjust your sensor distance for a preferred field. Installing a helical focuser on the camera side is a useful idea to refine focus but also to allow for some ...

Re: Polylite SC endusers(?)

Looks positive. Is your WPK 10X sitting on182mm above that top lens? It depends on where you want me to measure from. Right now it's 153mm from the top physical glass lens to the top of the WPK 6.3 eyepiece. So I'm 29mm sort of that. I do have some vertical adjustment in the Wild 40/14 adapter, but...

Re: 1/4 wave filter source

Bummer. The slider came out perfect, so I thought. I tried installing it in one of the rotating POL stages, but it doesn't fit. It seems hair is too thick, and I do mean hair. It's hard to describe the installation. The stage has to be disassembled, and the slider has to be placed inside. Once close...

This is just a preliminary update. I have been doing a lot of 3D printing and numerous revisions on multiple microscope projects, not just the Polylite scenario. :( I'm getting burnt out. Anyway, it seems I have succeeded with the camera setup to a certain degree, so that's great news. :D If you not...

It's designed to intercept the light cone and correct for chromatic aberration. Of course, I have no idea if it would work on a microscope; I ...

The inner bore appears to be 32mm, but I didn't measure it with calipers. The top of a WPK eyepiece won't fit in it, but the barrel will. Not...

That being the case, I'm not well versed in relay len setups and configurations. I've tried many combinations on the SC a year or so ago without success. That being the cas...
