11. Modern digital cameras filter out most of the infrared spectrum that their sensors detect. 12. The cool temperature means it emits most of its energy in the infrared spectrum . 13. In fact, the infrared spectrum is divided into two regions. 14. Pallas's visible and near-infrared spectrum is almost flat, being slightly brighter in towards the blue. 15. Kleman & Uhler observed the infrared spectrum and were the first to note absorption bands. 16. The infrared spectrum is similar to P-type asteroids but with a possible indication of water. 17. In astronomy, "'magnitude "'is a logarithmic measure of the brightness of an visible or near-infrared spectrum . 18. There are no water ice absorption bands in its near-infrared spectrum , which resembles that of Ixion. 19. The infrared spectrum of hydrogen chloride gas shows rotational fine structure superimposed on the vibrational spectrum. 20. Lumicera is transparent up to 10 micrometers, making it useful for instruments operating in mid-infrared spectrum .
