Examples in Context

  1. A microscope image formation model based on scalar diffraction and Fourier optics has been developed, which takes a slant angle between the optical axis and the observed surface into account.
  2. Measurements of refractive indices and optical axis of uniaxial crystal using Brewster angle method
  3. Application of Large-Aperture Collimator in Optical Axis(OA) Parallelism Measurement
  4. Electrical boresighting adjustment The important thing to know that it has an axis of symmetry - the optical axis.
  5. Telecentric operation ( field rays leave parallel to optical axis, unlike Barlow lenses which diverge rays ).
