D2 lamp (Deuterium lamp)
UV spectral lamp with long life (2000 hours in average), high stability and high intensity.
This lamp is used for various analytical instruments as UV Spectro light source.
We can meet the request for the lamp with MgF2 window.
We have various replacement lamps for major instrument manufacturers.
This lamp can be used for：
Spectrophotometer, High performance liquid chromatography, Atomic absorption spectrophotometer (background correction) and Film thickness meter
Output variation (30 minutes after lamp ignition):
Drift (variation of light output with passage of time): ±0.5%/h
Fluctuation (Max variation of light output in short period): 0.1% P-P
Average life: 2000 hours
