Examples
“Anyone who understands chemistry also knows that carbon dioxide is a gas that transmits visible light, but attempts to retain infrared radiation.”
“And here, made with the 31-inch telescope at UVa's Fan Mountain in the infrared, is M51:”
“I bet he sees everything in infrared like the Predator, too.”
“Yep, the greenhouse effect works because light in the visible spectrum passes through “greenhouse” gases, while reradiated infrared is absorbed.”
“Because the Predator can “sparkle” a target at night — mark it in infrared so that A-10 pilots and grunts on the ground can see it with their night-vision goggles — it opens up a range of options that pilots and infantry never had before.”
“A spectacular satellite image of Alaska's Malaspina Glacier in infrared, near infrared, and green wavelengths.”
“Essentially, the badges have 4 LED lights that light up when you get within infrared range of other attendees with similar profiles.”
“A spiral galaxy resembling our own - NGC 7331 in infrared, from Spitzer”
“(In the lab prototype, the video camera, with its built-in infrared beam, serves as the camera detector, while the projector is the neutralizer.)”
“It's explicit and erotic, but the choice to shoot in infrared transforms the human bodies onscreen into incandescent, glass-like forms.”

Tweets
Looking for tweets for infrared.
bilby All Italian verbs end in -re. Although the past participle would be something like infratto, assuming it had a regular conjugation. But anyway we can go ahead and make a plausible nonsensical sentence, thus:
Con la nuova macchina fotografica digitale, mi viene la voglia di infrare.
- With my new digital camera I get the urge to take infrared photographs.
I don't know why I bothered to do that but it was quite satisfying. Nov 19, 2009
milosrdenstvi For quite a while when young I supposed this to be the past tense of infrare. Infrared rays...I still see it! Similarly, I thought it very possible to misle someone. Nov 19, 2009
