Hi all,

I've been lurking this forum a bit but I've decided to join now and ask for help on a microscope. One of the best pieces of information I have learned from this website is the use of a Hayear 2307 camera. I primarily use that camera hooked up to a 24" LCD, although sometimes I'll switch to stereozoom through eye pieces. While the image quality isn't as good as viewing through the eye pieces, documenting my findings by being able to record video has been invaluable.

I use microscopy in several facets of my life:
  • Inspecting machined parts
    PCB assembly
    Camera inspection / assembly / troubleshooting
    Observing zooplankton (rotifers and nerite snail veligers)
    Attempting to diagnose / identify aquarium parasites
Until recently, I primarily used stereozoom microscopes (for many years, an unbranded stereozoom which I got from eBay, and more recently a Vision Engineering microscope). I also use a variety of both vision engineering and amscope microscopes at my day job. Recently, I acquired a Zeiss compound microscope (which I think is called a Zeiss standard, but I'm not sure). It has 6x, 10x, and 40x objectives and 10x eye pieces. It's also got an XY stage which is very helpful and has inspired me to purchase one for use under my stereo zoom microscope.

The issue that I'm having with this zeiss microscope (apparently third hand), is that what I believe is called the "swing out condenser lens" fails to stay in place. I tried using the most viscous grease I could find and that only made the situation far worse. The only way for me to currently use the microscope is to hold the swing out condenser lens in place, which is no fun. Any advice on this front would be greatly appreciated. This microscope also has delaminated eyepieces which I would eventually like to replace, but only once I resolve the swing out condenser lens issue.

If it is level, there is no reason for it to flip on its own.

The one I have does not have a washer on the handle, can't recall any having it. You might want to remove it.

It would seem to have been subjected to an unsuccessful/unorthodox repair job.


If you can't repair it, depending on your location they can be bought for the equivalent of around the €30/35 mark.

This is with a little patience of course. Ignore the outrageous asking prices of the auction resellers.

What is the swing up thing called? What is the part to look for?

Perhaps someones else can comment on whether the washer pictured above is original or has been added.

Even if very loose the 'flip top' should not flip on its own.

Is it seated correctly in the condenser holder?

Does the top lens look to be horizontal when in the 'up' position?

I can confirm that the washer is not on both of my 0.9 and 1.3 similar-looking Zeiss condensers. And yes, it would take some effort to flip the lens out from the stable vertical position. Regards,
