What is optical axis in physics? optical axis,the straight line passing through the geometrical centre of a lens and joining the two centres of curvature of its surfaces. Sometimes the optical axis of a lens is called its principal axis. The path of a light ray along this axis is perpendic...
Thin film coatings are often more durable than the optic’s substrate material, so coatings can also be used to protect the optical surface and extend component lifetime. The Coherent diamond over-coat (DOC) is a standout example of this. Given the truly vast scope of this topic, this ...

Most spectrometer designs use a single axis of dispersion - light is separated by wavelength only in one direction. When trying to measure very wide wavelength ranges, multiple diffraction orders can overlap. However, if a second dispersive element is added to the design these orders can be ...
I’ve read several posts talking about the reference wavefront, and to my understanding, the reference wavefront for an off-axis field is a sphere with a center that lies on the chief ray, and the sphere intersects the optical axis at the exit pupil plane. ...

Probe stations have four main components: probes, micromanipulators, a base station or stage and a microscope.
Optical mineralogy is the study of minerals and rocks by measuring their optical properties. Most commonly, rock and mineral samples are prepared as thin sections
A line through the optical center of a lens that is perpendicular to both its surfaces. Axis (botany) The main stem or central part about which organs or plant parts such as branches are arranged Axes One of three or four imaginary lines used to define the faces of a crystal and the po...
One of them, called spiral phase contrast, generates isotropic edge enhancement of thin phase samples or spiral-shaped interference fringes for thicker phase samples, which can be used to reconstruct the phase topography from a single on-axis interferogram. If SLMs are used for both illumination ...
