The mid-, near-, and far-infrared (IR) spectra of synthetic, single-phase calcium silicate hydrates (C-S-H) with Ca/Si ratios (C/S) of 0.41–1.85, 1.4 nm tobermorite, 1.1 nm tobermorite, and jennite confirm the similarity of the structure of these phases and provide important new ins...
GLASSES FOR THE CORRECTION OF CHROMATIC AND THERMAL OPTICAL ABERATIONS FOR LENSES TRANSMITTING IN THE NEAR, MID, AND FAR-INFRARED SPECTRUMSThe invention relates to chalcogenide glass compositions for use in a lens system to balance thermal effects and chromatic effects and thereby provide an ...
A dual-band multiple-quantum-well infrared photodetector capable of simultaneously detecting wavelengths near 0.9 μm and 10 μm has been fabricated using GaAs∕InGaAs step quantum wells. The detection of the near (0.82–0.95 μm)- and mid (9–11 μm)-infrared wavelength bands was achieved us...

Near infrared (NIR) spectroscopy of turquoise minerals from Arizona and Senegal with a formula of Cu(Al6–x,Fex)(PO4)4(OH)8.4H2O has been studied and a comparison of their NIR, ultraviolet-visible (UV-vis) and mid-IR spectra made. UV-vis and NIR reflectance spectroscopy is the most ef...
Experimental setup for near and mid infrared KTA optical vortex parametric oscillator. Full size image A low-Q cavity was formed of M1 and M2 with high reflectivity for the 1.064 µm (pump) beam, partial reflectivity (50%) for 1.4–1.6 µm (signal), and high transmission (> 97%)...
This geometry is consistent with the modest extinctions indicated from optical and near-infrared spectroscopy. The disk must be within 22° of face-on if... P. M. BRYANT,N. Z. SCOVILLE - 《Astrophysical Journal》 被引量: 188发表: 1996年 Mid-Infrared Spectroscopy of High-Redshift Submillimet...
Infrared Optics Many optical elements working in the visible spectral range can also work well in the near infrared, possibly with modified dielectric coatings. For longer wavelengths (mid and far infrared), one requires special infrared optics, which are often based on optical materials with low ...
the nearby (cz = 4600 km s-1) interacting spiral galaxy system UGC 12914/12915, using the ground-based Palomar 200 inch (5 m) telescope and PFIRCAM near-infrared detector and space-based mid-infrared imaging and spectral observations using ISOCAM and PHT-S on the Infrared Space Observatory....
