A factor of an equation of the Faraday effect, which is the rotation of the plane of light polarization by transparent materials in a magnetic field. Therefore, in the equation: where a is the angle of rotation, is the depth of the...

A metalens, short for "metasurface lens," is a type of optical lens that uses nanostructured materials to manipulate light...

A reticle, also known as a reticule or graticule, is a pattern or set of markings placed in the focal plane of an optical...

A prism is a geometric optical element with flat, polished surfaces that refract light. It is typically a solid, transparent...

An optical filter is a device that selectively transmits or blocks specific wavelengths, or colors, of light. Optical...

Phase contrast microscopy is an optical microscopy technique that enhances the contrast of transparent and colorless...

An opaque projector is a device used for enlarging and projecting images from opaque objects such as printed pages,...

A bundle of filaments of optical glass or other transparent materials that transmit only light, not optical images. The...
