Detailed explanation-1: -Solution : ‘m = L/(f 0)(1 + D/(fe)), “ “ m. = L/(f 0) (1 + D/(fe.))‘
Detailed explanation-2: -160 is a DIN (German Standard) measurement in mm of the tube length required for this lens. 0.17 is the thickness in mm of the required coverglass (0.17 is No. 1 coverglass)
Detailed explanation-3: -It’s very easy to figure out the magnification of your microscope. Simply multiply the magnification of the eyepiece by the magnification of the objective lens. The magnification of both microscope eyepieces and objectives is almost always engraved on the barrel (objective) or top (eyepiece).
Detailed explanation-4: -Compound Microscopes Typically, a compound microscope is used for viewing samples at high magnification (40-1000x), which is achieved by the combined effect of two sets of lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample).
