Our setup is an Olympus SZX-10 with both 1x and 2x objectives and 10x eyepieces. It's nice having the different objectives for different things--a close up look at a tiny crystal requires the 2x, but the 1x is less bulky and has better depth-of-field, so it's better for freezing crystals.
The DP21 camera is also nice, and provides for simple save-to-USB-drive photos and movies and scale bars, and also displays the field of view on an LCD monitor, which is nice for teaching and discussion among lab members. (To get the right value for the scale with a zoom microscope, though, it needs to be set up with the "objectives" as the zoom knob stop values and the "adapter" setting as the actual objective lens magnification. A bit of a workaround, but it's been fine for us.)

The scope will zoom from approximately 10X-90X magnification. At 90X a 400 nL drop in a 96-well plate will nearly fill the field. Cheers, _______________________________________ Roger S.

I would be very grateful if someone let me know the “objective” and “binocular eyepiece” specifications for SZX-7 or SZ-61 (Olympus) to get good magnification. Thank you. Regards, Prasenjit
