you are using a microscope with an objective lens with a numerical aperture of 0.75 and light source with a wavelength of 500nm what is the R?
Formula to calculate resolution:
Resolution(d) = wavelength/2*NA
NA= Numerical Aperture
Therefore
d=500/2*0.75
d=333.3

The objective of a microscope has magnifying power of 20×, a numerical aperture of 0.4, a working distance (WD) of 4 mm (~f ). For a wavelength of light of 450 nm, what is the resolving power of this objective? What is the diameter of its lens?
A microscope objective is used with a numerical aperture NA= 1.0 and immersion oil of refractive index n = 1.414. Assuming that the wavelength of light λ =0.486 µm, find the resolution of the microscope and its aperture angle α.

(1 point) READING 4 The resolution of a microscope is diffraction limited, just as the eye, but gains a significant advantage because an object can be placed very close to its objective lens. The smallest resolvable linear separation xTor an ordinary light microscope is: where λ is he wavelength o light used, and Θ ls he half Viewing angle 0 he obiective The quantity n sne s ca e the num enca aperture of he obiective where n s the...
Light of wavelength 589 nm is used to view an object under a microscope. The objective lens of the microscope is the lens that gathers light from the object being observed and focuses the light rays in order to form an image of the object. It acts as the aperture of the system, determining its resolution. In this case, the objective lens is circular, of diameter 0.95 cm. Assuming that the resolution of the microscope depends solely on the diffractive...
With light of wavelength 550 nm and a lens with a numerical aperture of 0.47, what is the minimum resolvable separation of two objects (micrometers)?
2. A microscope has a 1.1 cm diameter objective lens with a

Experiment 22: The Compound Microscope f2 Object 2 1 (Objective Lens)d L, (Eyepiece) d#150mm The Compound Microscope A compound microscope uses two lenses to provide greater magnification of near objects than is possible using a single lens as a magnifier. The setup is shown above. The objective lens, L1, functions as a projector. The object is placed just beyond the focal point of L1 so a real, magnified, inverted image is formed. The eyepiece, L2, functions as a magnifier. It...
Give the numerical aperture values for the following objectives (get these values from the microscope in front of you): 4X _______, 10 X _______ and 40 X _______. Numerical aperture means what? __________________________________________.
RESOLUTION: This property of the compound microscope is the degree to which the detail in the specimen is retained in the magnified image. It is the ability of a microscope to distinguish two closely spaced objects as separate and distinct entities. Conventional light microscopes have a resolution of about 0.2 μm. RESOLVING POWER (d) is the closest spacing between two points at which the points can still be seen rly as separate entities. The smaller the resolving power, the smaller...
