A total of 26 healthy volunteers, with a mean age of 32 years, were examined with and without one drop of 1% tropicamide being administered 30 min previously. On each occasion, acuity and pupil ...

An achromatic lens, often called an achromat, is a type of optical lens capable of correcting chromatic aberration, a distortion that occurs when glass splits white light into multiple ...

Precise control of light is a crucial requirement in optical imaging, sensing, and communication. Traditional lenses employed for the purpose have limitations, necessitating more precise and compact ...

When a single spherical lens is used with a polychromatic light source, different wavelengths do not focus to the same point, creating a colour distortion (colour fringes) within an image. This effect ...
