Learn about the different types of optical prisms, such as dispersive, reflective, beam-splitting and polarizing prisms, and how they refract, reflect or split light. Find out how prisms are made of transparent materials like glass, acrylic or fluorite, and how they can create spectra, images or polarizations.
Optical glass is a type of glass suitable for optical systems such as lenses, prisms or mirrors. It contains additives to modify its optical or mechanical properties, such as refractive index, dispersion, transmittance and thermal expansion.
Learn about the origins and development of optics from ancient times to modern days. Explore the contributions of Greek, Roman, Islamic, and European scholars to the fields of geometrical, physical, and physiological optics.
A dispersive prism is an optical device that uses refraction to split white light into its spectral components (the colors of the rainbow). Learn about the principle, types, history and applications of dispersive prisms, and how they differ from diffraction gratings and mirrors.
In a roof prism without a phase-correcting coating, s-polarized and p-polarized light each acquire a different geometric phase as they pass through the upper prism. When the two polarized components are recombined, interference between the s-polarized and p-polarized light results in a different intensity distribution perpendicular to the roof ...
Glasses, also known as eyeglasses and spectacles, are vision eyewear with clear or tinted lenses mounted in a frame. They can be used for vision correction, eye protection, cosmetic purposes, or viewing specific visual information.
Crown glass is a type of optical glass used in lenses and other optical components. It has low refractive index and low dispersion, and is produced from alkali-lime silicates containing potassium oxide. Borosilicate glass Schott BK7 is a common crown glass.
Prentice's rule is a formula to calculate the amount of prism correction in a lens based on decentration and lens power. It can be used for prescribing, tolerance control, or determining unprescribed prism in eyeglasses.
