Fresnel lenses can capture more oblique light from a light source, thus allowing the light from a lighthouse equipped with one to be visible over greater distances. Fresnel lenses were later produced, being used for automobile headlamps, brake, parking, and turn signal lenses, an

Beam splitters When a light beam is incident onto a surface inclined at an angle of incidence to the incoming beam, the reflected and transmitted light becomes partially polarised. This can be resolved into two components defined as s and p polarisation. This effect of an incline

Roof prisms also called amici prisms or right angle roof prisms, do two things invert the image and bend the line of sight through a 90° angle They are excellent as prism diagonals in optical systems, because they erect the inverted image. Also ideal for use in spotting scopes,
