molybdenum disk heat radiation, the difference between Di

heat radiation, the difference between Di
Objects thermal radiation will produce a variety of different frequencies molybdenum disk (wavelengths) of electromagnetic waves. For tungsten, the incident surface waves are absorbed almost one hundred percent. (Suck
Radiation coefficient close to 1) for tungsten, the incident surface waves is almost one hundred percent will be absorbed (absorption and radiation coefficient is 1) so the thermal radiation received
Near blackbody radiation spectrum only related to temperature. So close to the thermal radiation tungsten sheet spectrum of blackbody radiation related to temperature only.
Difference dysprosium
The easiest way: There are two kinds of materials to make a big difference lamps, dysprosium lamp color temperature is about 5600, there will fluctuate because of the aging of the lamp
Tungsten wire
What, are generally around 5600K. Tungsten color temperature is molybdenum wire 3200K! This is the biggest difference between the two, dysprosium lamp is white, incandescent light is yellow, dysprosium lamp was
Many models are not the same, in order to prevail ARR lamps, dysprosium lamp includes: 200W, 575W, 2000W, 2500W, 4000W, 6000W, 12000W still new
PAR lamps, dysprosium lamps also belongs, 200PAR, 575PAR, 1200PAR, 4000PAR, 6000PAR, 12000PAR Tungsten include: 50W, 300W, 650W,
1000W, 2000W, 5000W, 24000W!
