  • Lenses and Geometrical Optics - Common Optical Defects

    Microscopes and other optical instruments are commonly plagued by lens errors that distort the image by a variety of mechanisms associated with defects (commonly referred to as aberrations) resulting from the spherical geometry of lens surfaces. There are three primary sources of non-ideal lens action (errors) that are observed in the microscope.

  • An introduction to off-axis parabolic mirrors

    2013-10-21u2002·u2002Off-axis parabolic mirrors (OAPs) can be a useful tool in optical design. OAPs combine the achromatic and diffraction limited imaging properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most imaging systems. However, when used improperly, OAPs can be difficult to align and achieve ideal imaging.

  • Reflected Light DIC Microscopy

    Reflected light DIC can be performed using the Nikon LV100N POL upright microscope. The primary function of a vertical illuminator is to produce and direct semi-coherent and collimated light waves to the rear aperture of the microscope objective and, subsequently, onto the surface of a specimen.

    The optical power is defined as the reciprocal of the focal length measured in meters and is specified in units of diopters. When we view far away objects, the distance from the middle of the cornea and the flexible lens to the retina is 0.017m. Hence, the optical power of the human eye is, or roughly 60 diopters.
