Coma - Similar to spherical aberration in many respects, coma is generally encountered with off-axis light rays and is most severe when the microscope is out of proper alignment. The aberration is named for its strong resemblance to the shape of a comet tail, and is manifested by a streak of light that appears to emanate from a focused spot at the periphery of the viewfield.
Get PriceFiber Optic Basics. Optical fibers are circular dielectric wave-guides that can transport optical energy and information. They have a central core surrounded by a concentric cladding with slightly lower (by ≈ 1%) refractive index. Optical fibers are typically made of silica with index-modifying dopants such as GeO 2.

The c axis also passes through the intersection of the a axes set at right angle to the plane formed by the a set. c Hexagonal division: nine forms 7 classes 6-fold symmetry Trigonal division: six forms 5 classes 3-fold symmetry In some classifications: Rhombohedrial Crystal System
Get Price2013-10-21u2002·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.
Get PriceThe residual coma in a lens system is usually combined with other off-axis aberrations, making its individual contribution to final image quality difficult to evaluate. Field curvature In most optical systems, the final image must be formed on a plane or flat surface. Unfortunately, most optical systems tend to form that image on a curved surface.
Get PriceA theodolite works by combining optical plummets (or plumb bobs), a spirit (bubble level), and graduated circles to find vertical and horizontal angles in surveying. An optical plummet ensures the theodolite is placed as close to exactly vertical above the survey point. The internal spirit level makes sure the device is level to to the horizon.
Get PriceThe equation shows that for θ → 0 (i.e., propagation along the optical axis) we obtain n → n o, and the observed birefringence vanishes: one obtains n o for any polarization direction.. One distinguishes positive and negative uniaxial crystals; in the former case, the extraordinary index is higher than the ordinary index..

A mineral is biaxial positive if β is closer to α than to γ.; In this case the acute angle, 2V, between the optic axes is bisected by the γ refractive index direction. Thus we say that γ is the acute bisectrix (BX A), because it bisects this angle.; If a table of optical properties of minerals reports the 2V angle, it usually refers to this acute angle.
