Optical axes include the optical axis and the visual axis, which form the angle kappa. This angle kappa has is an important clinical parameter, which has implications when it comes to refractive surgery, cataract surgery, strabismus, and even surgeries involving the retina and macula. See more There are two significant optical axes of the eye – the optical axis and the visual axis, which are also referred to in literature as the pupillary axis and the line of sight, respectively. The … See more The optical axis, the visual axis, and the angle kappa are represented on physical exam by the distance between the pupillary center and the corneal light reflex. The angle kappa has been further measured by different … See more WebDispersive prisms, usually in the shape of a triangular prism, are used to separate the different wavelengths of an incident beam of light into different optical paths. Each wavelength will be deflected at a different angle by the prism shape thus changing the refractive index for each wavelength.

WebJan 29, 2013 · The wide-angle baseline and the narrow-angle baseline then become identical, with the advantage that a wide-angle measurement provides directly a measurement of the narrow-angle baseline, at a level of accuracy better than the 100 μm presented in Section 1. In practice, this coincidence turns out to be very challenging.
WebOptical fibers usually are specified by their size, given as the outer diameter of the core, cladding, and coating.
