Magnification of scanner objective lens
WebThis is called the depth of field. The formula for the depth of field is: where: “n” is the refractive index of the material between the objective and the sample. λ (lambda) is the wavelength of light. NA is the Numerical Aperture. In most cases the material between the objective and sample is air, and “n” equals 1.00. The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample. The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.
