large plano convex lens,
The majority of light microscopes have an objective lens of some kind, which includes both compound microscopes and stereo microscopes. These types of microscopes are also the same in that each type has an eyepiece or ocular lens.
The objective lens and the ocular or eyepiece lens are in combination responsible for magnification of the specimen being observed.
Total magnification = Objective magnification X ocular magnification
Therefore, for 10X objective and 10X ocular the total magnification = 10 X 10 = 100X
This means that the specimen being observed is now 100X it’s actual size.
The majority of compound microscopes come with interchangeable objective lenses, which have different magnification powers. This commonly includes 4x, 10x, 40x, and 100x objective lenses.
Optical AR Coatings
a) Uncoated,The surface reflectivity of uncoated visible lenses(Refractive index＝1.5) is about 4%.
e) We can also customize high damage threshold antireflective coatings
