3. Prism correction - Wikipedia

   en.wikipedia.org/wiki/Prism_correction

   The most common application for this is the treatment of strabismus. By moving the image in front of the deviated eye, double vision can be avoided and comfortable binocular vision can be achieved. Other applications include yoked prism where the image is shifted an equal amount in each eye.

4. Chromatic aberration - Wikipedia

   en.wikipedia.org/wiki/Chromatic_aberration

   Chromatic aberration. In optics, chromatic aberration ( CA ), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point. [1] It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light.

5. Distortion (optics) - Wikipedia

   en.wikipedia.org/wiki/Distortion_(optics)

   The Micro Four Thirds system cameras and lenses perform automatic distortion correction using correction parameters that are stored in each lens's firmware, and are applied automatically by the camera and raw converter software. The optics of most of these lenses feature substantially more distortion than their counterparts in systems that do ...

6. Digital microscope - Wikipedia

   en.wikipedia.org/wiki/Digital_microscope

   Digital microscope. An insect observed with a digital microscope. Entomologist using a digital microscope to magnify a miniature insect. A digital microscope is a variation of a traditional optical microscope that uses optics and a digital camera to output an image to a monitor, sometimes by means of software running on a computer.

7. Prism (optics) - Wikipedia

   en.wikipedia.org/wiki/Prism_(optics)

   An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides.

8. Differential interference contrast microscopy - Wikipedia

   en.wikipedia.org/wiki/Differential_interference...

   The second prism recombines the two rays into one polarised at 135°. The combination of the rays leads to interference, brightening or darkening the image at that point according to the optical path difference. This prism overlays the two bright field images and aligns their polarisations so they can interfere.
