Trinocular compound microscope provides high magnification for biological use and educational applicationsTrinocular viewing head with vertical camera mount and Siedentopf binocular mount with interchangeable pairs of 10x widefield and 16x widefield eyepieces and sliding head with 55 to 75mm interpupillary adjustment, fixed 30-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharingForward-facing nosepiece with 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic precision-ground optical-glass objectives that provide color correction of magnified imagesBrightfield, halogen illumination with rheostat to control light intensity, and 1.25 NA Abbe condenser with iris diaphragm and rack-and-pinion focus control for precise focus, clear examination, and light controlDouble-layer mechanical stage with 1mm stage divisions and stage stop; graduated coarse and fine focus with tension control to prevent stage drift
>How do I figure out what magnification I am getting in the view? Do I like multiply the eyepiece number by the objective number? The eye pieces say like 10X, 20X etc (what exactly does that mean? it doesn't really change the picture maybe just the FOV?) and the objectives say 4X, 10X, 40X and 100X.
Pretty much, yes. The specs here list this scope as having a magnification range of 40-1600x, which is 4x Obj 10x Eye up to 100x Obj 16x Eye. Technically your magnification will also change depending on how you resize the image digitally (e.g. you enlarge it in Microsoft Word) so scale bars, if you can add them, give you a better idea of the image scale.
>My guess is that if I used oil it would go better
The specs also list that the 100x Obj uses oil immersion to function, which is why it doesn't appear to work without it.
