Home educated teen who is interested in bio-medical field. We are beginning High School biology this year.
All metal construction, metal internal adjustments and metal screws
Achromatic & DIN : 4x & 10x
Super High Contrast Achromatic, DIN, Retractable : 40x
Super High Contrast Achromatic, DIN, Retractable, Oil Immersion : 100x
Two 10x Wide Field DIN
One Additional 10x Wide Field DIN with grid overlay for drawing
reverse-facing, ball bearing, quadruple nosepiece
I still can’t get a solid reading on which will give me the best illumination without cooking our water samples
I do know that I need easily found replacement bulbs
Halogen, Fluorescent, or LED
Rheostat control for light source so I can dim if it is too bright
Abbe 1.25 NA movable/focusable condenser
Built-in mechanical stage
all metal rack and pinion gearing system with slip clutch
Coaxial Course (22mm graduation or better) Fine (.002mm graduation)
I might need to get a darkfield condenser so I need a microscope that is standardized so I can add onto it later when the kids want to start studying blood cells etc.

The top tier are the Nikon, Zeiss, Olympus, and Leica. The next tier are companies like Unico, Lomo, Motic.... Actually you can go with the top tier affordably. You can Choose the Nikon Eclipse E100. You can add darkfield to the Eclipse E100 and Nikon makes the grid reticule you are looking for. As far as "cooking" your samples, what are you observing? An LED illuminator will lower the amount of heat but may not be bright enough for darkfield or higher magnifications(1000X).
