Parabolic reflectors are pretty handy devices ... We doubt this process can be optimized enough to produce astronomy-grade mirrors for visible light, but it still has a lot of potential applications.
Also called a "dish" or "mirror," parabolic antennas are used for satellite signals and planetary telescopes. The reflective mirror design can also emit energy such as in a flashlight or ...
For a visible light telescope at a wavelength of 400 nanometers, this means a parabolic mirror needs to have a surface finish that is perfect to within 40 nanometers. That’s the size of viruses ...
Using proprietary production techniques, and benefiting from an ultra-stable production facility, Optical Surfaces Ltd has ...
