The application of electronic devices or circuits that comprise both electrical and optical functions, which are used to convert electrical signals to visible or infrared energy, or vise-versa. I.e., a thin-film semiconductor device.
SPHERICAL VS. ASPHERIC LENSES
HOW THEY’RE USED IN IMAGING APPLICATIONS
Optical Lenses are often categorized by their shape. Two common surface shapes are spherical and aspherical. Each offers unique characteristics that make it suitable for different use cases.
