Refraction of light by Spherical Lenses

Refraction is the change in direction of light when it passes from one medium to another. The working of a lens is based on the refraction of light when they pass through it. Lens is a piece of ...

Optimizing Space Imaging Systems Using Telecompressor Optics

For example, a 0.71x telecompression factor delivers an effective aperture gain of approximately one stop. This means that the system is able to operate at lower ISO values or higher shutter speeds, ...

Comparison of higher order aberrations in eyes with aspherical or spherical intraocular lenses

Total, corneal, and internal aberrations were measured using ray-tracing technology in 23 eyes implanted with aspheric (Tecnis ZA9003) IOLs, and in 25 eyes implanted with spherical (AcrySof SA60AT) ...
