Short-wave infrared (SWIR), or near-infrared (NIR), which covers 0.7 – 3.0 micrometers. Mid-wave infrared (MWIR), which covers 3.0 – 5.0 micrometers. Long-wave infrared (LWIR), which covers 8.0 – 14 micrometers. Wavelength ranges between these ones cannot be used in the Earth’s atmosphere due to absorption by various molecules.
What is SWIR? Short-wave infrared (SWIR) light is typically defined as light in the 0.9 – 1.7μm wavelength range, but can also be classified from 0.7 – 2.5μm. Since silicon sensors have an upper limit of approximately 1.0μm, SWIR imaging requires unique optical and electronic components capable of performing in the specific SWIR range.
Nov 15, 2011· It is well-known that cellulose is difficult to dissolve in common organic solvent and be directly processed into porous membrane. In this work, using ionic liquid, 1-allyl-3-methylimidazolium chloride (AMIMCl) as solvent, high flux and anti-fouling cellulose nanofiltration (NF) membranes were fabricated by phase inversion method from 8.0 wt.% of cellulose/AMIMCl solutions.
The optical materials selected for an optical system depend upon the application, the required system performance and the environment in which the system is to perform; thus the materials’ optical, mechanical, thermal and thermo-optic properties must be taken into account. There are three major bands that are worked with when optical systems are used within the Earth’s atmosphere.
