Definitions

1. At optical wavelengths, the center of the galaxy is dominated by a large bulge.

Second Optical Wavelength

1. A first one of these optical wavelengths is highly absorbed by water vapor while the second optical wavelength is only slightly absorbed by water vapor.

Infrared

1. Interferometer arrays produced the first extremely high-resolution images using aperture synthesis at radio, infrared and optical wavelengths.

Optical Spectrum

1. The method includes irradiating blood with optical radiation having a selected range of optical wavelengths to produce an optical spectrum.

Light

1. In recent years there has been intense interest in developing ways to guide and manipulate light at dimensions much smaller than optical wavelengths.

Milky Way

1. It is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.

Galactic Center

1. No matter how much we want to, it is next to impossible to observe anything at the Galactic Center at optical wavelengths.

Telescopes

1. The heavens are studies in the submillimeter, infrared and optical wavelengths with telescopes designed specifically for each of these spectral regions.

First Demonstration

1. In 1996, Thomas Krauss made the first demonstration of a two-dimensional photonic crystal at optical wavelengths [8].

Optical Wavelengths

1. Radio telescopes are much larger than optical telescopes because radio wavelengths are much longer than optical wavelengths.
2. Although these nebulae appear different at optical wavelengths, they all appear to be bright sources of emission at infrared wavelengths.
