Re: Zeiss Citoval 2

Zeiss jena stereos don't have the same optical reputation as Zeiss wests. Then again I've seen a lot of delaminated west zeiss stemis offered for sale which Jena microscopes don't struggle with to the same extent. The smz-2t is quite nice but 650 seems steep for one. Thr citoval is mpdular but that'...

Re: Nikon gene sequencer objectives

Note there are two types of these nikon oem objectives. I don't think the exact difference has been nailed down (maybe different cover slip thicknesses?)

Re: Nikon DSLR, Labophot-2, DiagInc HRD* adapters as a solution?

Due to regrettable historical naming conventions a 1" sensor is actually 9x12mm, much smaller than aps-c. The 'nikon mount' they reference is an old bayonet mount used on small-sensor industrial cameras which nobody uses anymore or even makes adapters for. I have one of these which I'm going to make...

With a 1x hrd adapter on my olympus szh it vignetted strongly. It is designed to cover a 1" sensor.
How you need to modify it depends on exactly which nikon head you have unfortunately. Some are easier than others.

Re: Nikon DSLR, Labophot-2, DiagInc HRD* adapters as a solution?

Thr hrd adapters will not cover a dslr sensor. DI adapters to cover aps-c are ruinously expensive. Fortunately nikon objectives will natively cover aps-c (but not full frame) with no intermediate optics, which is the best solution for image coverage and quality as far as I have been abke to tell.

Re: AmScope T580B VS Swift SW380T

There is no modern microscope that won't accept c mount cameras, though they may require an adapter. The swift likely has a 23mm eyepiece at the top meant to accept standard c mount adapters with reduction optics.

Re: Amscope Super Widefield vs Extreme Widefield eyepieces?

Yeah, with any ultrawide eydpieces you also need optics that can deliver a good image across that ultrawide field of view. That's a lot easier on a stereo microscope with lower magnifications and resolution, while it's usually a more specialized feature on compound objectives. I am not sure how far ...

Re: Amscope Super Widefield vs Extreme Widefield eyepieces?

The only difference should be how big the image you get is (as in, how much you can see--magnification is the same, but the bigger the field number the less of the available image is cropped off). 20mm is ok but about the bare minimum for a modern microscope. 22mm is going to be noticeably nicer, bu...

Re: Barlow 2.0x vs higher power eyepieces, implications?

The big difference is that eyepieces magnify the image you already have, while the auxiliary lens is grabbing an inherently higher mag, higher resolution image. Practically speaking, a barlow lens is going to halve your working distance and double your resolution, while 20x eyepieces double mag but ...

Re: Wild Heerbrugg M8 broken prism alignment and or service manual

Good, this is the simpler one.
Just to clarify, have you already opened it and examined the prisms? If not, you can try gently shaking it to see if a prism is rattling.
There are other failure modes, but this is by far the most common.

Depends what head is on there. If it's the simpler one they can sometimes be saved by opening them up, realigning the prism using the broken epoxy that previously held it like a puzzle piece and regluing. Plus side this is easy and not insanely expensive to replace thanks to modularity. Compatibilit...

Re: New to everything related to microscopy, what should I do?

This is probably the easiest solution https://www.ebay.com/itm/124336976571 Not sure if the swifts need eyepiece correcrions, if so they'll miss them with this setup. Either way it won't give 100% perfect results but it is fast, easy and should be at least OK. If you find you need better photos ther...
