WebAug 13, 2014 · Using Sal's equation in an earlier video, we have that (do/di) = (ho/hi). In a hypothetical example, let's assume the height of the original image is 8 cm. Using the rest of the values from the video, we get (24/-6) = (8/x). Solving for x yields -2, which means that the image is inverted. Although the magnitude is correct, according to this ... WebFeb 27, 2024 · The purpose of the homogenous immersion system is to match (as closely as possible) the refractive index and NA of the front lens of the objective, the immersion medium, glass coverslip/slide, the mounting medium, and (in principle) the lens of the condenser (refer to Figure 2 and Table 1). Placing immersion liquid on the lens of the …

A perfect air lens, meaning the gap between the front element of the objective and the sample is filled with air, can have a maximum NA of around 1.0 due to the refractive index of air. google rating on website

Webwhere n is the refractive index of the imaging medium between the front lens of the objective and the specimen cover glass, a value that ranges from 1.00 for air to 1.51 for specialized immersion oils. Many authors substitute the variable α for µ in the numerical aperture equation. From this equation it is obvious that when the imaging medium is air (with a … WebNumerical Aperture (NA) = η • sin (α) (1) where α equals one-half of the objective's opening angle and η is the refractive index of the immersion medium used between the objective and the cover slip protecting the specimen (η = 1 for air; η = 1.51 for oil or glass). By examining Equation (1), it is apparent that the refractive index is ... WebFor 20X magnification, which can be a numerical aperture of 0.6 to 0.8, the depth of field drops to about plus or minus 500 nanometers. Moving into high magnification with oil immersion at a numerical aperture of 1.47, the depth of field drops very dramatically, And the depth of field could be plus or minus 0.1 to 0.2 microns (100 – 200 nm). google rating salon black beauty
