The bias and poor reproducibility, of the Ugg Stockists Uk Online Sartorius balance when sizing particles (below Ugg Factory Outlet Uk about 10 μm) is attributable to the high and variable loss of sample around the balance pan. However, when using the correct end-weight as estimated graphically by the method of Harris and Jowett rather than the empirical constant of 92% recommended by the manufacturers, errors are eliminated. The resulting size distribution agrees with that determined with the balance pan developed by Leschonski, which overcomes the loss problem but is much more tedious to operate. We have designed and fabricated two-color infrared light emitting diode (LED) emitting in the wavelength regions of 3–4 μm and 5–10 μm. The interband cascade (IC) LED device was grown on n-type GaSb substrate and has 30 cascaded stages for the long-wave infrared (LWIR) and 15 cascaded stages for the mid-wave infrared (MWIR) emission bands. The two active regions are separated by a 0.5 μm thick contact layer, which is used for biasing the two LEDs. Both room temperature and cryogenic temperature results show emission in the wavelength regions as designed.
