... Distance between the intersection of marginal rays and the paraxial focus, Fi, is known as the LSA (longitudinal spherical aberration). Note: SA is positive for convex lens and negative for a concave lens. TSA (transverse SA) is the transverse deviation between the marginal and paraxial rays on a ...

Synchronized ti scattering microscopy
... For CRS microscopy, collinear pump- and Stokes-beams are coupled into one of two modified laser scanning upright microscopes (BX61WI/FV300, Olympus for SRS imaging and TCS-SP5, Leica for video-rate CARS imaging). We use a 60x 1.2NA water immersion objective (UPlanApo / IR, Olympus) to focus the beam ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
