This is my first new topic in the Cloudy Days & Microscopes forum.
However, I have spent a lot of time since my early teens playing with microscopes and observing the microcosms in prepared slides and drops of water. I have also used microscopes to introduce young people and other budding scientists to the wonders of microscopy.
For quite some years I have owned a second (third?, fourth?) hand Olympus CH microscope for several years which I have used exclusively for hobbyist purposes. It was handed down to me from my grandfather who AFAIK purchased it from a an acquaintance who got it from a liquidated veterinary practice. This microscope it is clearly in a different optical league than my other microscopes, but its age is clearly showing: spare parts are hard to come by, the tungsten halogen light source gives an unnatural color to specimens and is causing wet samples to dry up and kills the objects I'm observing unless I'm very careful. I did made an improvised dark-field disc for it which works reasonably well but I would like to use dark-field more properly. A couple of years ago I was able to get a quick peek through a high-end Olympus optical microscope (I don't recall the exact model, but it was something in the 10,000 $ class) in an optical lab, and I was like "oh, wow... I didn't know optical microscopes could be that good".
Since my CH microscope is now probably 40 years old I was wondering if anyone can tell me if newer-generation microscopes like the Olympus CX23 or CX33 series would offer real advantages over my CH microscope. I'm speaking mainly of optical quality, but also eye relief and upgradeability. I am normally wearing eyeglasses compensating for astigmatism but the eye relief on my CH microscope's eyepieces is too tight for that. Is eye relief generally better on modern microscopes or are long-eye relief eyepieces something I need to purchase as an upgrade? Dark-field ability would also be nice, but I don't need high-power for that.
I'd appreciate your advice and thoughts on this .
