Objective Lens Focal Spot Size at Robert Grigsby blog

Objective Lens Focal Spot Size. The spot sizes that can be achieved at three common raman microscopy wavelengths using a high magnification air objective lens (100x 0.9 na) are illustrated in figure 2. This calculator computes the 1/e^2 1/e2 spot diameter of a collimated gaussian beam whose wavelength is \lambda λ and diameter at lens d. Find the focal length that allows you to achieve the desired beam spot size, or input the depth of focus to calculate the focal length. For an objective that is not infinity corrected, the system is designed to take a diverging light source located at 1 focal distance f1 f 1 in front of the lens (object plane) and image. 1) with shorter wavelength lasers offering smaller spot sizes and improved spatial resolution. Based on the na n a, the optical system's magnification. The spot size depends on the laser wavelength (eq. Estimating the focused spot size of your objective lens in a laser scanning microscope. I am trying to figure out how to approximate the spot size of a laser beam that is focused using a microscope objective where. When an optics vendor provides a spec for an objective lens, they often provide a numerical aperture value (na n a). Cornell university) the following focal volume.
