The scanner could see in all visual wavelengths as well as X-ray and infrared.

The visual wavelengths were useless-we couldn't see a thing through the ports-but the microwave sensors let us look to the horizon.

Detailed descriptions are rare, due to their encounter suits ability to "cloak" themselves to visual wavelengths of light.

I followed his gaze, shifting clumsily along the visual wavelengths.

He deduced that much from thermal imaging; visual wavelengths were completely blocked by the cloud of dust and smoke rising above the explosion.

Its surface is one of the most reflective (at visual wavelengths) in the solar system, with a visual geometric albedo of 1.34.

It puts out more energy than 10,000 suns, although more than 90% of it at longer than visual wavelengths.

As the Sli absorb the different atoms, the chemical reaction could cause different visual wavelengths to be absorbed.

There was just as obviously nothing returning to the ship in visual wavelengths, or the spotters posted at the observation ports would have reported it.

There was nothing to be seen yet, of course, not in visual wavelengths, but Spock was ready with his modified sensors and he instantly took a reading.
