A cold cathode is a cathode in a gas-filled electron tube that is not heated by a filament. The voltage potential within the tube is sufficient to ionize the gas and cause the current to flow.
UV cold mirrors, hot mirrors, and UV Dichroic filters. UV neutral density filters commonly consist of thin alloy films applied to a UV fused silica substrate. These flat spectral response filters work ...
UV cameras are a style of video camera that have been optimized for capturing light from the ultraviolet spectrum. This is accomplished by using a UV-pass filter, which will only allow light below the ...
“All five of those characteristics depend on the cathode material,” says Alan Nelson, chief technology officer and sector chief executive for new markets at Johnson Matthey, a global leader in ...
Such a small tube, with a cold cathode and a low anode voltage ... So while one of them was in the UV eraser (built from an old sun-tanning lamp), I could debug the code and program another ...
But there is little you can do for the common cold and other respiratory illnesses, especially once you get sick. Most are caused by viruses, so you cannot cure them with antibiotics, which are ...
A cold begins when a virus attaches to the lining of your nose or throat. A doctor can usually tell if you have the flu based on your symptoms, especially if it’s during peak season. Bird flu ...
e.g. Deuterium lamps Hollow cathode lamps, PID lamps, Tungsten lamps, UV/Vis Spectrometer lamps, Vacuum UV lamps, Flash lamps, CW lamps, UV LED systems.
Promise. Cosmopolitan Video Editor Sarah Ng uses this UV and LED lamp to do her acrylics at home. "It's lightweight and super easy to use whenever and wherever you need it." She loves that the ...
Sturdy and reliable, the cold-cathode displays found their way into everything from scientific instruments to test equipment, and even some of the earliest computers and the equipment that formed ...
