Re: Motorized Rotating Display Stand
You don't know what a record player is, BKT? The model I'm looking at is a Modular Component Systems MCS 6601. It has a direct drive DC brushless motor and has set speeds of 33.33 rpm and 45 rpm.

Re: Motorized Rotating Display Stand
My current setup is an old computer fan connected to a potentiometer. When I have it running slow, the pen slows it down further to a complete stop. When I have it running faster, the paint no longer stays in nice circles. What I'm looking for is something with constant torque and preferably electri...

Motorized Rotating Display Stand
I was thinking of getting one of these on Amazon for making circular obliques and darkfield stops using paint pens. These can also be used for slide ringing. Any thoughts on this? https://www.amazon.com/JAYEGT-Motorized-Rotating-Turntable-Photography/dp/B08K35HPJ4/ref=sr_1_8?crid=1Q25V5PMFVN38&dib=e...

Re: Micro Safari Aqua
I think it is 2 to 3 pieces of acrylic glued together and a resealable film of LDPE to allow gas exchange while holding in water vapor. I don't know if this can be used with polarized light microscopy. Also, flushing it out with peroxide would be safer than using alcohol as alcohol destroys acrylic.

Olympus UIS2 Objective Finder
When using this "online catalogue" you will notice the labeling on the objective doesn't exactly match what is on the website. For example: PLAN N 4x is PLN4X. I can't seem to find my PlanC N 4x though.

Expanding Darkfield Stop
The reason these aren't made anymore is that they are expensive to make and they tend to be fragile due to the small parts they contain.

Re: Olympus U-CA
Thanks for the small lesson on numerical aperture. Multiplying the N.A. number by 1000 makes perfect sense especially since the maximum limit of light microscopy is 1500x and the largest N.A. of any 100x oil objective I have seen so far is 1.45 https://www.spachoptics.com/NIKON-MRD01905-p/nikon-plan...

Olympus U-CA
Before I consider getting one I would like to know if the magnification changer causes any image quality problems. Also, if the numerical aperture has to be increased for the objective being used. If I get a 60x objective I can "boost" it up to 120x by setting the U-CA to 2x?
