The design and fabrication approach of a dichroic beamsplitter to meet the protection requirements infrared detectors for blinding laser weapons is presented. must protect against 1064 532 nm lasers have high transmittance in detection beam band 3.6–4.7 µm. In order realize antireflection (AR) functions beamsplitter, Ta2O5, which has wide gap thermodynamic stability, was selected as high-refrac...

This paper describes the development of a prototype of a low-cost digital fluorescent microscope built from commercial off-the-shelf (COTS) components. The prototype was tested to detect malignant tumor cells taken from a living organism in a preclinical setting. This experiment was accomplished by using Alexa Fluor 488 conjugate dye attached to the cancer cells. Our prototype utilizes a torch ...

Optical Sciences Corporation has designed and implemented a 116 inch exit pupil relief optical system for dynamic infrared scene projection to flight table mounted seekers at the U.S. Army Missile Command (AMCOM) Research, Development, and Engineering Center (RDEC). The optical system collimates the output from a 512x512 element resistor array in the 35μm waveband. The large pupil stand-off is ...

Apolipoprotein B, the polypeptide moiety of human serum low density lipoprotein, is subject to degradation (as evidenced by sodium dodecyl sulfate-polyacrylamide gel electrophoresis) both in the intact particle and after delipidation. Protease inhibitors, sodium azide, and nitrogen saturation did not influence the rate or degree of degradation. Lipid-free apolipoprotein B prepared by gel exclus...

The orientational characterisitics and the temperature dependencies of the molecular apparent tilt angle of a partly fluorinated chiral smectic liquid crystal (/S/)-4-(1-methylheptyloxycarbonyl)phenyl 4'-[6-(3,4,4,4-tetrafluoro-3-trifluoromethylbutylcarbonyloxy)hexyloxy] biphenyl-4-carboxylate (acronym MHPHFHHOBC) are studied using the polarized Fourier transform infrared (FTIR) spectroscopy. T...

We have used attenuated total internal reflection infrared spectroscopy (ATR-IR) spectroscopy to study the association of the C2 domain from protein kinase Cα (PKCα) with different phospholipid membranes, so as to characterise the mode of membrane docking and its modulation by the second-messenger lipid PIP₂. In parallel, we have also examined the membrane interaction of the C2 domain from cyto...
