Why do many stage lighting brand light beams have color bias phenomenon?
One of the accepted standards in the instrument industry is the use of low pressure mercury lamp to detect the wavelength accuracy of the instrument, because the line spectrum produced by this mercury lamp is stable and reliable. Line spectrum more obvious such as 253.7nm, 365.01nm, 435.8nm, 546.1nm and so on for a few more obvious, and very narrow bandwidth is very narrow, can be used to detect instrument wavelength accuracy, repeatability and wavelength bandwidth of the wavelength
In fact, it consists of some lines of different wavelengths. Mercury lamp has low pressure mercury lamp and high pressure mercury lamp, their characteristic spectrum is basically the same, but the intensity will be somewhat different. Because it is a mixture of light of different wavelengths, so after three prisms, of course, the spectrum will be separated by different refraction angles (that is, our common rainbow).
On the first floor is a master, explained so comprehensive, I have to study hard.It is found on the Internet that mercury lamp generally produces white light.
