Optical lens design
open-in-new
<p>Optical lens design is the process of <a href="/facts/Engineering_design_process/heCF3wFo">designing</a> a <a href="/facts/Lens_(optics)/ejlH6n5c">lens</a> to meet a set of performance requirements and constraints, including cost and manufacturing limitations. Parameters include surface profile types (<a href="/facts/Spherical/jywYLNM2">spherical</a>, <a href="/facts/Asphere/cSatFMFd">aspheric</a>, <a href="/facts/Holographic/4J1gW0M6">holographic</a>, <a href="/facts/Diffraction/Mk80xXHT">diffractive</a>, etc.), as well as <a href="/facts/Radius_of_curvature_(optics)/22RwFXIP">radius of curvature</a>, distance to the next surface, material type and optionally tilt and decenter. The process is computationally intensive, using <a href="/facts/Ray_tracing_(physics)/VKdjk6Sc">ray tracing</a> or other techniques to model how the lens affects light that passes through it. </p>
