Bulbs of the movie theater type are large high pressure xenon DC arc lamps. To ask what temperature they are does not make much sense. The arc itself is 600 K. The lamp envelope is quartz or sapphire and while it would certainly sizzle your finger, the temperature depends on the cleanliness of the bulb, the cooling airflow, the wattage, the type of lamp and the age of the lamp.
They are 15kW lamps. Imax projectors use 2 of them.
Each lamp produces 600,000 lumens. If you put a log in front of it, it would spontaneously combust...
Asking the temperature of the lamp makes a lot of sense. The 600k that you mention should be 6000k and is the colour temperature and has nothing to do with the actual temperature of the lamp whilst operating. It is merely the best way to describe the colour of the light when compared to the black body locus on the CIE Chromaticity Map.
The clear quartz glass jacket of the lamp has an operating surface temperature of about 1,300 degrees. To prevent the lamp from overheating, it has coolant "jackets" that allow cool distilled water to be pumped around the electrodes at a rate of a little over 30 litres per minute at about 100 psi. In addition, an exhaust fan removes about 34 cubic metres of air per minute from the lamp housing.
A stereomicroscope is 3D and a compound light microscope is 2D.
No, this is because none of the light is filtered. Therefore this will harm your eyes even more.
Chromium is a 3d element. and cobolt also a 3d element.
Enzymes work best at around body temperature. It the temperature is too cold then the enzyme activity slows down to almost zero. The activity of the enzyme steadily increases to a temperature of around 50 to 55 oC depending on the enzyme. After that temperature the enzyme is denatured and ceases to function. At 45 oC the enzyme is most likely still functioning but is close to the temperature where it will be destroyed.
Battery powered 3D glasses means they are active 3D glasses and they only work with their own manufactured brand. However the compatibility of passive 3D glasses for other TVs are much higher. They work on any 3D TVs or theaters if they use the same passive technology. The passive 3D TV glasses are also lightweight due to no batteries being attatched. Plus, they don't need to be charged everytime before/after use unlike the active ones.
In theaters and IMAX in Disney digital 3D and IMAX 3D

Yes, in fact Alien in the deep was shot in IMAX 3D format.
They make it 3D from sony pictures.
yes
They make them using special IMAX video cameras.

NO
IMAX and domestic television are two very different things. While there are many fine 3D televisions to choose from, none will appear the same as an IMAX image.
Avatar is out in a regular format, as well as digital 3D and IMAX 3D.
That's correct
November 2004 was the first IMAX 3-D Movie, which was The Polar Express.
