20x eyepiece
Posted: Tue Mar 07, 2023 7:44 pm
About a year ago I got a new Olympus microscope with DIC capability.
I love it but...
My old microscope a Zeiss Ultraphot had an Optivar which I quickly realized had spoiled me.
An Optivar is another set of lenses between the objective and the eyepiece.
In my case I had 12.5 power eyepieces and 10, 40, 100x objectives. The optical had settings of 1.25x, 1.6x and 2x
That meant with a 40 power objective I could get very close to 1000x without oiling things up. (12.5 x2 x40) Granted I was probably getting empty magnification at the 2x setting.
With my new Olympus the jump was 10 to 40 to 100.
Often I wanted more than 40 but didn't want it bad enough to oil things up.
Recently I purchased a 40x 1.15NA water objective. As a result I also purchased two 20x eyepieces.
This gives me 800X capability without oil and with no empty magnification!
I thought I would only use the 20x eyepieces occasionally but I put them on about 2 months ago and haven't gone back.
Anyone else have experiences with 20x eyepieces?
The 20x also just happens to be closer to my camera field of view with a 5x projection eyepiece.
