Difficult temperature measurements, such as on tenter frames for extremely thin films, use thermometers employing precise narrowband
infrared filters. This technique enables the device to measure the surface temperature of film without looking through the film or being influenced by the background.
With its new Colorcomp Infrared (IR) colorants, LNP now offers custom compounding of broadband
infrared filters designed to preferentially allow specific infrared wavelengths to pass through a plastic part.
The camera, dubbed FourStar and installed in December 2010 on the Magellan 6.5-meter telescope in Chile, features five specially designed
infrared filters that deliver an unprecedentedly precise combination of wavelength resolution and low-light sensitivity, thereby enabling the team to accurately measure the distances to thousands of different galaxies at a time, including those too faint to be detected through previous methods.
Difficult temperature measurements, such as on tenter frames for extremely thin films, use thermometers employing precise narrow-band
infrared filters. This technique enables the device to measure the surface temperature of film without looking through the film or being influenced by the background.
Difficult temperature measurements, such as on tenter frames for extremely thin films, are readily accomplished using thermometers employing highly precise, extremely narrow-band
infrared filters. This technique enables device to accurately measure surface temperature of film without looking through the film or being influenced by the background.
