Nick Morris finds photonics products are helping scientists better understand the universe around us

Although the basic optical theory and design of most telescopes deviates little from those used in the 17th century, the precision to which they can be built is orders of magnitude greater, driven primarily by continuous advance in precision optics and associated photonics products, produced by companies such as Optical Surfaces, which makes many components to be used in astronomical instruments, such as ultra precise mirrors, prisms and aspherical optics. Advances in optical design software from companies like Lambda Research give astronomers the tools with which to model their devices.
