4.4. Important part of the instrument
4.4.1. Power Board: The 110-220V/50Hz-60Hz power conversion and regulation
outside access to the necessary equipment: 11.5V (tungsten lamp power), +12
V (fan power, electrical power), +5 V (computer system power), + /-15V (signal
board power supply), deuterium lamp filament preheating and lit power
deuterium lamp is lit up and the power breakdown.
4.4.2. Light room: there are tungsten halogen lamp and deuterium lamp source
device to automatically switch.
Tungsten halogen: visible spectral region. Applicable wavelength range 340-
1100nm. Because it uses the principle of halogen cycle, it has a greater
intensity of light emission and longer life. As the halogen cycle requires a higher
temperature. Thus lamps commonly used quartz glass or high temperature
glass. Tungsten halogen lamps emit energy in the visible region around the
operating voltage is proportional to the fourth power, therefore, to make light
stable, the model has a stability of less than 0.2% of the power supply, the other
imported Philips halogen socket tungsten halogen lamp replacement to ensure
stable and easy to use and long life.
Deuterium lamp: suitable wavelength range of 190-340nm. When deuterium
lamp operation, maximum energy sources in the vicinity of 230nm, 486.0nm and
