| Abstract: | WSHg - B type mercury quartz lamp with low pressure dot source and high-frequency ON - OFF power supply was designed based on glow discharge principle and an analysis method of evaluating wavelength uncertainty was put forward. The wavelengths of spectral lines in the region of 200 ~ 700 nm emitted by the WSHg - B type mercury quartz lamp are accuracy for calibrating the wavelength of most general spectrophotomeler because of uniformity distribution and stabilization. WSHg - B type mercury quartz lamp can be used to calibrate the spectral bandwidth and resolution of spectrophotometer. |
| Keywords: | low pressure mercury quartz lamp spectrophotometer calibration wavelength development |
