There is a difference between a modern microscope objective and an imaging point. The lens is the most complex and important part of a microscope, working in a wide beam of light (large aperture), but these beams are smaller than the tilt of the optic axis (the field is small). The ...

Parts of a Microscope Every microscope has an eyepiece lens, which is the lens at the top that you look through. A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens. The eyepiece lens is usually 10x or 15x power (i.e., what ...
Keep the microscope covered to prevent the build-up while it is being stored. HOW TO USE THE MICROSCOPE: 1. Turn on the lamp. 2. Place a sample of what you wish to observe on a slide. 3. Move the mirror so it reflects(反射) light from the room up into the objecti...
Why aren't the magnifications of both ocular lenses of a binocular microscope used to calculate total magnification? Why do lenses have two focal points? In bright field microscopy, why should the front lens be removed from the light path when using the...
The focusing device has a positioning unit (20) having a base portion (22) on which a lens holder (24) is movably mounted for holding an objective lens (26). An actuator (27) moves the lens holder alo
A microscope objective lens has, in the following order from the object side, a front group having positive refracting power to convert a beam from an object into a convergent beam, and having a positive meniscus lens element with a concave surface facing the object side, and a cemented ...
