Re: Another beginner looking for Microscope Selection help

You probably want both a stereo and a compound, yeah. It is possible to do a but of both in one scope, but it is always a bit of a compromise, so outside of some specific applications it makes sense to just have one of each. Plus side, your budget is big enough to get both in style. This one just ca...

Re: LWD objective on 0.18 cover slip slide.

Do you have a lens between the camera and eyepiece? Most Zeiss setups of this era would have used one.

Attaching your camera is relatively easy. Leitz microscopes use afocal by default which is the easiest.

Re: 23mm diameter 10x/22 eyepieces (!)

Just a quick note, I tried a pair on an AO 580 and was pleasantly surprised. It takes some adjusting but parfocality is within range, and visually it's quite good. The magnification is a little less than 10x in this system, and the covered FoV is a little bigger than the 145 so they even out to abou...

Re: What microscope has this style?

You won't find a cheap one with that capability built in. You'd probably need to adapt a coaxial illuminator meant for normal light. My plan for one is to use a Nikon optiphot with infinity-corrected optics, maybe with a customized stage to get more working distance. I haven't specced it out entirel...

Re: Help needed with focus stacking

The M3z is a nice scope. It is modular, so it's possible to add a trinocular port/camera adapter intermediate between the head and body. These adapters are compatible throughout the entire Leica and Wild M series (aside from the M5 and M4), so almost any camera port from the past 50 years of Wild-Le...

Re: What microscope has this style?

I still don't understand how wavenumber is supposed to make comparable numbers independent of the nm laser used. Raman spectroscopy looks at the shift between the input wavelength and what bounces back, which is independent of input wavelength. So what you're graphing is the spectrum of the raman s...

Re: Magnification or Enlargement?

The difference comes at the final enlargement when you view the image on the screen. With a small camera sensor you are cropping the edges of the image and then blowing it up to the same final size. Optically the camera adds no magnification but the final result is as if it is.

Re: So, will I get the optics clean (Wild drawing tube)?

My experience with Wild stuff is that they're made to be possible to service. That said, they sometimes applied light threadlocker to screws as well, which can be a pain to get through. Probably not on this one though.
A hurricane/squeeze blower would be a good idea here.

That is quite inexpensive for this model.

Re: B&L Stereozoom Photography ?

You can illuminate the light path and look down it (careful not to dazzle your eyes) to see if anything looks wrong. That's probably easiest, it would have to be a dramatic problem with the mirror I would think. I don't currently have an sz7 set up for photography at my place unfortunately, too much...

Re: Various eye pieces

Some are interchangeable (nikon's are pretty much) others less so. And even if it works, getting a wider field number that looks good also depends on the head and objectives being able to deliver an image big enough and corrected out to the edges which isn't a guarantee either.

Lower mags are more sensitive to eyepiece position than higher mags--maybe it's out of position? The trinoc port on an sz7 is very simple, it's just a couple 45 degree mirrors, one which extends into the light path, plus a glass window. There shouldnt be an easy way for that to degrade image quality...

Oh yeah, you don't want a c mount adapter for that camera. Adapting your Sont should be easy, though there aren't any 100% ideal solutions for aps-c on a bh2--there will be tradeoffs in framing, image quality or price.
