New far-infrared and submillimeter data are used to solidify and to extend to long wavelengths the empirical calibration of the infrared spectral energy distribution (SED) of normal star-forming galaxies. As was found by Dale et al. (2001), a single parameter family, characterized by fν(60μm) fν(100μm) , is adequate to describe the range of normal galaxy spectral energy distributions observed b...

After industrial coating processes lacquer has to to be dried with the help of heat. Often this is done by hot air or infrared systems. Compared to other technologies Infrared heat needs less space and provides energy exactly where it is needed. Infrared drying has the best results with material which has a simple geometric shape. But if the oven is designed appropriate to the requirements lacq...

This Chapter covers recent advances in Short Wavelength Infrared (SWIR), Medium Wave‐ length Infrared (MWIR) and Long Wavelength Infrared (LWIR) materials and device technol‐ ogies for a variety of defense and commercial applications. Infrared technology is critical for military and security applications, as well as increasingly being used in many commercial products such as medical diagnostics...

Rockwell has begun developing infrared FPAs in the 2048 format. The first is the HAWAII-2, an infrared 2048 focal plane array (FPA) for next-generation infrared astronomy. It will supplant our HAWAII 1024 as the largest high-performance infrared imager available. As with our prior infrared FPAs, the flip-chip hybrid will consist of a low dark current, low-capacitance HgCdTe detector array mated...

Digital camera sensors are sensitive to wavelengths ranging from the ultraviolet (200-400nm) to the near-infrared (700-100nm) bands. This range is, however, reduced because the aim of photographic cameras is to capture and reproduce the visible spectrum (400-700nm) only. Ultraviolet radiation is filtered out by the optical elements of the camera, while a specifically designed “hot-mirror” is pl...

We present mid-infrared (10.4, 11.7, and 18.3 m) imaging intended to locate and characterize the suspected protostellar components within the Bok globule CB54. We detect and confirm the protostellar status for the nearinfrared source CB54YC1-II. The mid-infrared luminosity for CB54YC1-II was found to be Lmidir 8 L , and we estimate a central source mass ofM 0:8M (for a mass accretion rate of Ṁ ...
