From the early floor and polished prism features of glass lighthouse Fresnel lenses to trendy microreplicated versatile Fresnel lenses for sunlight concentrators, new functions of prismatic optical elements for gentle keep watch over are consistently being constructed. furthermore, thoughts using unmarried and compound prismatic and reflective optical elements are rising within the fields of metrology, polarization keep an eye on, projection structures, illumination, and demonstrate lighting fixtures, between others.
Like several classical Greek texts on technological know-how, Euclid's works on optics at the start got here to the West frequently via medieval Arabic texts and commentaries. whereas a number of Greek types of the Optika have been came upon and translated as early because the 16th century, checking out what can have been Euclid's unique has now not been effortless.
