Light transmission optics Dietrich Marcuse

(Phys.org) —The ability to guide, bend and focus light at the nanoscale is a highly sought-after goal in the field of nano-optics. I checked the optics and I could not detect any light cutoff from the prisms. Optical engineering advancement produces a generous 3.3 inches of constant eye relief while decreasing overall scope length to 13.9 inches. Technically, all fiber optic cables transmit data at the speed of light, but the transfer material can slow that down. Best-quality glass is fully multi-coated to allow maximum light transmission. And while the speed of light in air isn't close to max speed in a vacuum, it beats typical glass handily. The binoculars are phase corrected and the optics are fully multicoated, ensuring excellent light transmission. Precise and "Full Control of Nanoscale Optical Transmission with a Composite Metascreen. 'The common wisdom in optics is that if you have a metal film with very small holes and you plug the holes with metal, the light transmission is blocked completely,' said Chou, the Joseph Elgin Professor of Engineering. Extraordinary light for nano-optics.
